Goehrisch COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB001 Pg001 FIB 00002 08/31/81 *** S-80 TACF feature *** The purpose of the S80 TACF feature is to provide a means of communicating asynchronously to a serial RS232C device. Although the MBF VDT (7250/7270) falls into this classification, testing will find that this physical configuration will not work properly. When communicating from a 13XX CPU to a VDT, mnemonics (e.g., 'CS', 'BS', 'CL', etc.) are used. The Level 3 or Level 4 operating system "interprets" these mnemonics and converts them to the appropriate hexidecimal value that the VDT can functionally understand. On the S80 system, however, device mnemonics often interpret to very different hexidecimal values that the intelligence of an MPC can functionally respond correctly to. However, because of their different hexidecimal values, a 7250/7270 VDT will not be able to respond to mnemonics issed from and interpreted by the S80 Level 5 operating system. The interconnection of a VDT to an S80 MPC is truly like connecting a non- Basic Four serial device. Nothing would occur automatically. All cursor controls, screen positioning and data formatting would have to occur character-by-character, position-by-position. Should the hexidecimal values for a VDT be made available, functionally this configuration could be made to work. They are not, however, available at this time. ORIGINATOR: SAM TREMBLAY COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB002 Pg001 FIB 00003 08/31/81 *** S-80 asyncronous communications to 13XX CPU *** Among the many features of the S80 Terminal Asynchronous Communications Facility (TACF) is the ability to provide modem clocking which essen- tially ensures protection against any form of sporadic data loss and error conditions. This is handled through the manipulation of 12 modem signals (detailed in the TACF manual. MBF #5117). Asynchronous communi- cations on the 13XX CPU's, however does not support modem clocking as the modem connection uses only four signals. For this reason, receiving data with a 13xx CPU has a potential for sporadic data character loss or buffer overrun (Error 34). The maximum protection against data loss/buffer overrun can be offered by configuring Input Buffering for a minimum of 100 characters (available on Level 4.2A and above). This will not guarantee no data loss but will provide the maximum insurance possible. For these reasons, caution should be exercised when attempting to communicate between S80 and 13xx systems. Please note that asynchronous communications between S80 systems have no such limitations or cautions applicable. There are many features to the TACF that make this a very desirable configuration in network where the volume of data is such that lower rates of transmission speed will suffice.

System gives error 05 or no response at all. It was found that if a character was keyed seventeen times, all seventeen characters came up on screen. Cause and Correction: Codex modem has an option for a seventeen character delay. All modems from factory are set for seventeen character delay and won't work on Basic Four systems until they are re-strapped for a one character delay.

Field Product Support has received several calls regarding this subject. The MAI Basic Four Modem Configuration Reference Manual (M0114A) and Worldwide Product Support Hardware Announcement #16 both state that these modems support either asynchronous or synchronous data communications over dial-up telephone lines. They will not operate over leased phone lines. At this time, customers with this requirement will have to use an outside source for this equipment. ORIGINATOR: Tom Nedbal COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB006 Pg001 FIB 00007 07/06/90 *** Paradyne/Ark Modem Problems on SPx Systems [ WPSF 611 ] *** Two problems have been reported by the field when Paradyne FDX 1200/2400 Plus or ARK 24K Plus modems are connected to SPx systems. PROBLEM #1: When modems are configured for ATP as recommended in the Modem Configuration Manual M0114A the modems may lock up or respond erratically after rebooting a 2000/3000/4000 system. CAUSE: This problem is caused by the modem responding to characters sent to it by SPx systems while rebooting. When configured for running ATP the modem must dial out in response to the commands sent to it by the ATP program. Therefore, in command mode the modem can be confused by the escape sequence sent to it while rebooting a 2000/3000/4000 system. SOLUTION: The solution to this problem is to simply leave the modem off until the boot routine is completed. This will ensure the modem will not be sent the escape sequence while the system is rebooting. PROBLEM #2: Another problem occurs when the modems are used for auto- answer only (dial-in) applications. A user dials into an SPx port and after finishing his work hangs up. The host modem's Tx and Rx lights will continue to flicker as if the user were still connected. The SPx port will even appear as a task and therefore keep the port hung rendering it useless until cleared by killing the process. CAUSE: This problem is caused by the modem responding to characters sent to it by the SPx port but this time the modem returns a result message. This result message causes the SPx to respond with the login screen which again causes the modem to return a result message. This endless closed loop causes the port to hang. SOLUTION: The solution to this problem is to configure the modem to be "deaf and dumb". This is done by: 1. Set DIP switch S2 Positions 3 and 6 DOWN. 2. Power the modem OFF and ON. 3. Check the CTS light on the modem. It should now be off when the modem is idle. Both problems are due to the fact that the Paradyne and ARK modems are "smart" modems. These modems can be configured to respond to Hayes commands and to return a result message if desired. The modems can also be configured to be totally "deaf and dumb" and then not respond to any commands or return any result messages.

Error 0 results when remote MBF terminals or PC's are performing slave printing. SYMPTOM: When the DM424 is set for factory defaults and used as a host modem, a user dialing in may experience an error 0 in BASIC when performing slave printing using a BFIS interface printer. CAUSE: The BFIS protocol computes an LRC (Longitudinal Redundancy Check) of characters within a block. When the LRC takes on a hex value of a DC3 (XOFF), the host modem by default will halt forwarding data to the host. This results in a timeout to BASIC which then issues an error 0. SOLUTION: The host end DM424 must be configured for XON/XOFF pass-through. This will allow DC1 (XON) and DC3 (XOFF) characters to be forwarded to the remote terminal as data. To set up the host modem for XON/XOFF passthrough do the following: Connect the host end DM424 to a terminal using a "straight through" cable and enter the following AT commands: >AT&F&W Loads factory options and stores them in NVRAM. >OK Modem response message >ATZ Loads options stored in NVRAM. >OK >AT*F1 This enables XON/XOFF (Passthrough) >OK >AT&W This stores configuration in NVRAM.

Increasing the value of registers S6 and S7 should prevent this timeout. For FDX 1200/2400 modems SW2 position 8 must be "up" or ON. This ensures storage of new register values when power is lost.

The main status byte contains the status of the hardware. The auxiliary status byte is software dependent and unique to the particular application program which is resident within the controller at the time the status is read. This FIB gives a description of the main status byte only. | MAIN | AUXILIARY | --------------------------------- |7:6:5:4:3:2:1:0|7:6:5:4:3:2:1:0| --------------------------------- STATUS BYTES The main status values differ between usage in system mode and monitor mode. Monitor mode indicates that the IMLC is under PROM control. This is true before and during the time that the IMLC is being loaded. After the load is completed, the IMLC immediately enters system mode and runs under the control of the IMLC OS. MONITOR MODE OF OPERATION - SELF-TEST: To display the controller self-test status from BASIC in console mode, enter the statment as follows: ENTER: OPEN(1,TRK=0)"10" The above statment causes the controller to execute the self-test. In the event of a self-test failure, the status will be returned and dis- played in hexadecimal as follows: ERROR 5 STS=FFCO ---- | | | -------->AUXILIARY | | ---------->MAIN The self-test main status codes are as follows: 80-- All self-tests completed successfully 82-- ROM checksum incorrect 84-- ROM's RAM is defective (BE7D-BFFF) 86-- Lower memory is defective (4000-7FFF) 88-- Upper memory is defective (8000-BFFF) 8C-- CTC is defective 9C-- PIO is defective 9E-- ICOM channel control error A0-- ICOM channel data error A2-- XCOM channel controller error A4-- XCOM channel data error D6-- DMA 1 block move error D8-- DMA 1 read error DA-- DMA 1 write error E6-- DMA 2 block move error E8-- DMA 2 read error EA-- DMA 2 write error COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB010 Pg001 F6-- DMA 3 block move error F8-- DMA 3 read error FA-- DMA 3 write error Note that if main status returned is hex 'FF', this indicates that inter- upts are not being received from the controller. This indicates that the system sees the controller as nonfunctional. Also NOTE that the auxiliary status byte has no meaning during self-test. SYSTEM MODE OF OPERATION: Following the self-tests and loading by the CPU, the controller enters the system mode of operation. The main status byte shown below is for reference only, since it will not normally be returned to the operator. Rather, the software will convert the status into a BASIC code for pro- gram handling, and the appropriate error displayed to the operator will be the BASIC error code.

Since Stat Mux's incorporate their own protocol to allow efficient use of idle time, error checking and automatic retransmission of data on detection of errors, this protocol may conflict with the protocol used by BFISD peripheral software drivers and printer spoolers. Stat Mux's utilize data buffers to retain data until it has successfully reached its destination. As a means of controlling the flow of data between the mux and the host, the mux uses X-ON/X-OFF (DC1/DC3, CTRL-Q/ CTRL-S, hex 11/13), RTS/CTS (Request-to-Send/Clear-to-Send) or DTR/DSR (Data Terminal Ready/Data Set Ready) to signal the host that its buffer is 'almost full'. BFISD systems do not presently support RS-232 line control (RTS/CTS or DSR/DTR) but does however, utilize the X-ON/X-OFF characters as flow control in the terminal or special serial drivers. Use of Stat Mux's on BFISD equipment must therefore be used with caution and with an understanding of what data is being sent to and from these units. SERIAL PRINTERS BFISD printers with the 'BFISD' protocol utilize ACK/NAK protocol for data integrity and flow control. This method works very well in direct- connect (local) or remote applications using asynchronous modems or Time Division Multiplexers (TMD's). Problems can occur however, when these printers are remoted through intelligent devices such as Stat Mux's since the serial printer drivers do not use the X-ON/X-OFF characters as a means of flow control. More importantly, transmissions from the host to the printer contain an LRC character at the end of each print line for verifi- cation of data integrity. Further, the seven byte status sent from the printer to the host contains non-printable bytes to indicate the precise status of the printer and last received message. Therefore it is very possible that the data stream to (frequent condition), and the status bytes from (infrequent condition) the printer may contain bytes that the Stat Mux may interpret as control data to be acted upon. For example, printing "CUSTOMER NUMBER : "+STR(N:"000000") will cause an LCR character of $13$ (X-OFF) to be sent to the Stat Mux over 65,000 times for all possible customer numbers! This means that in each occurrence the Stat Mux will probably 'hang'. Slew commands to certain printers require the use of bytes corresponding to the X-ON/X-OFF character codes. Therefore setting the VFU or slewing to channel 4 can cause the Stat Mux to hang since the byte for channel 4 is the same as an X-OFF command. Additionally, since the serial printer drivers do not support X-ON/X-OFF for flow control, should the Stat Mux signal the host that a 'buffer almost full' condition exists by sending an X-OFF character, the probability is that data to the printer will be lost or a time-out error condition will be reported to the applications software. TERMINALS AND SPECIAL DEVICES Terminal and SPE ports support the use of X-ON/X-OFF for flow control and generally work well with Stat Mux's utilizing this method of control. Unless the terminal or SPE applications software utilize the X-ON/X-OFF ASCII codes for data or other control, no problems should be encountered. For example, COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB014 Pg001 OMS utilizes a CTRL-S in text mode for a 'SELECT' command. This would cause the Stat Mux to hang until a CTRL-Q were sent from the terminal ('CHARACTER INSERT' command). RECOMMENDATIONS The successful utilization of Stat Mux's requires an overall understanding of the problems as detailed above as well as consideration of each customer's system usage. The duty activity of each device attached to the Stat Mux, the transmission speed of the trunk line, and the buffer capacity of the Stat Mux are items to consider in setting up any Mux for proper operation. PRINTERS In general, the use of serial printers using the BFISD protocol is not recommended over Stat Mux's. If, however, such use is necessary, it is required that the applicable Stat Mux port is configured for no X-ON/X-OFF flow control. Since flow control is then disabled, the Stat Mux buffer must be controlled by device activity and baud rate to prevent data loss due to a buffer full condition. Once the buffer size has been determined from the Stat Mux specifications, adjust the activity and baud rates of the attached devices to ensure the buffer will not become full. A conservative guideline is that the combined baud rates of the devices should not exceed twice the trunk baud rate. For 8000 Systems, where BFISD protocol is used, and where problems still exist, special printer drivers may be used which prevent LRC transmission (and therefore a certain amount of error checking). These drivers are available by contacting the customer's dealer. Note however, that the use of these drivers will allow certain transmissions to be printed (if possible) even though they may contain transmission errors. TERMINALS AND SPECIAL DEVICES In general, terminals and special devices may be remoted through Stat Mux's using X-ON/X-OFF flow control with little problem. Exceptions include, but are not limited to, terminals with slaved printers, applications software utilizing 'CTRL-S' and 'CTRL-Q' as operator keyed input characters (commands), and foreign devices using full eight bit binary data (as opposed to ASCII characters). Slaved printer terminals require the same cautions as indicated in the PRINTER RECOMMENDATIONS previously detailed due to the Slew and LRC characters. Applications software should not utilize 'CTRL-S'/'CTRL-Q' as valid operator key strokes (commands). Where necessary, this type of connection will require disabling the X-ON/X-OFF flow control in the Stat Mux. Foreign devices utilizing binary data where 11hex and 13hex are valid character patterns will require that the X-ON/X-OFF flow control be disabled. Again, attention to buffer size will be required to prevent data loss. ORIGINATOR: J. RIPPL COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB014 Pg002 FIB 00015 06/04/84 *** 13XX communications selector problems on Level 4 *** If a system is configured for 19 or more terminals and communication is active on the system as well, the communications selector "*COMM" may display confusing and erratic information. This condition will occur if "TI" is started or released or if ESCAPE is pressed during screen initialization. Only the execution of the Selector program "*COMM' is affected. The observed behavior is that the communications screen will not display all of the options for the TBC system, sometimes displaying only two or three of the selections, and sometimes not displaying any selections at all. "*BCOM" and ",BCOM" execute correctly. The problem is due to a logic error in the coding that determines what "I" devices are configured on the system, and can be easily corrected by adding a single line of code to the selector program "*COMM". First, LOAD "*COMM" into memory, and then type the following: 0055 IF T$(1,1)="T" THEN LET T$=T$(7); GOTO 0055 ELSE GOTO 0070 Then SAVE"*COMM".

It incorrectly transmits program files via File Transfer between Basic Four systems. The result is that programs transmitted from level 4.4B systems can be received with Error 30's resident within their coding. The problem is resident in the transmit package and does not affect receiving program files via File Transfer on the 4.4B system. A simple patch to the File Transfer program ",BXMTF" will completely alleviate the problem: In CONSOLE mode, LOAD ",BXMTF" LIST 3265 3265 DIM X9$(0) Append to Line #3265 the following code (type exactly as shown). 3265:;LET D9=0 Then inspect the line again by listing it. LIST 3265 3265 DIM X9$(0); LET D9=0 SAVE ",BXMTF" A patch had been included in the 4.5A release. However, since some customers have retro-graded back to LEVEL 4.4B, these sites are now experiencing the Error 30 program transfer problem.

FRATER COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB016 Pg001 FIB 00017 10/03/84 *** 27xx/37xx ASCII transparency *** The transparency mode of 27xx/37xx transmissions is not supported when using the ASCII line code. Although this has not been stated previously in any Basic Four documentation, IBM manuals for 27xx/37xx specify that these terminals cannot transmit or receive ASCII data in transparent mode. In addition to transparency, the Basic Four File Transfer mode is also unsupported when using the ASCII line code as it uses transparency in its transmission protocol. When using the EBCDIC like code, all modes of transmission (Text, Transparent, and File Transfer) are supported. It is recommended, for this reason and because of better error checking logic, that the EBCDIC line code always be used when communicating between Basic Four systems and if possible, to non-Basic Four systems.

Rippl COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB021 Pg001 FIB 00022 05/01/86 *** Hayes 2400 baud modem notes and HARMONY setups *** Some precautions on setting up the Hayes 2400 Baud Modem on a 2000 system and using Harmony with either a DS-500 workstation or IBM PC. 1. Ensure on Harmony under Modem Initialization Sequence that there are no commands specified, and that Hang Up Sequence is AT H(backslash)013, also ensure Dialing Prefix Sequence is set for AT DT (if tone) or AT DP ( if pulse). 2. To perform a hang up the customer while in Terminal emulation must wait 1 second after last keyboard entry then type +++ the modem will respond with OK then pressing function key F10 and typing H for hangup will force the modem to hangup. 3. After the Hayes 2400 Modem at the 2000 side has been setup for Baud rate, parity, autoanswer, speaker volume, and so on it would be wise to disable Command Echo, and disable Result codes so that there will be no interaction of the 2000 system port receiving echoed back characters from the modem when the system boots (false parity errors on 2000 system ports). 4. Important!!!!! - configure the available port on the 2000 system for VDT 7270 or EVDT with no protocol. Upon a hang up of the Hayes 2400 modem it was noticed with a Data Scope that the modem sent about 20 characters of garbage characters into the 2000, almost every time there was a hex D3 (XOFF) in the 20 characters of garbage. This locks up the port from transmitting any further data and also prevents the terminal from being released, until a hex D1 (XON) is transmitted back to the 2000 system port. To test for a XOFF as a cause of a locked up port, depressing CNTRL Q will send an XON back to the port and transmission should resume normally. Copyright 1985, Synex Systems Corp.

The application at the transmit side will generate LINE BID NOT ACKNOWLEDGED errors due to the IMLC drivers passing an illegal ESC character within the ID. The recieve side not recognizing the ID will reject the bid until transmit side terminates the session with the LINE BID ACKNOWLEDGED message. To work around the problem install drivers from a release prior to 8.4D (such as 8.4C). Simply copy the files ().R4C50.SYS.TBCA for port A or ().R4C50.SYS.TBCB for port B into the node ().Rxxxx.SYS.TBCA or ().Rxxxx.SYS.TBCB respectively (xxxx should be replaced by the updated software prefix you are replacing i.e 5C15). As a precaution the 8.4D/8.5C/9.5C drivers should be backed up prior to replacement. The 8.5C release did address problems encountered when using extremely dirty lines. Fixes for these bugs are not available in 8.4C. If the user did not experience any problems on 8.4C, he should return to that release of the drivers.

Since the File Transfer (FXFER) option in the transmit queue uses transparency to send files, FXFER is NOT supported when the transmission code is defined ASCII. Whenever possable, EBCDIC should be used as the transmission code for BCOM sessions. EBCDIC not only supports trasparency but also has better error detection capabilities for transmission errors. If ASCII transmission code is required for a particular session, files must be sent and received in TEXT mode. Please note that ASCII transparency is also not supported by IBM.

This problem occurs only when both systems have specified a BQR created transmit queue for a single session. The BQR utility creates transmit queues in the following format as viewed from the transmit queue definition screen in the TBC application. TRANSMIT QUEUE DEFINATION SCREEN: NO. FILE TYPE CHAIN 1 FILELIST FXFER NO 2 DATAFILE1 FXFER NO 3 DATAFILE2 FXFER NO . . . X LASTFILE FXFER TERM The option TERM in the CHAIN field causes the session to terminate immedi- ately after one system transmits the last file in its transmit queue. Consequently, the other system has no time to complete its transmit queue. Verify the problum by checking the received BQR list. If the BQR utility displays the NF (not found) status on some of the files, then the last file in both transmit queues must be modified in the TBC application to change the CHAIN field to NO from TERM (terminate). This will enable both systems to complete their transmit queues. To change the CHAIN field follow these procedures on both systems. o Enter the BCOM application and select mode menu option (2) QUEUE DEFINITION o Select queue definition option (2) DEFINE TRANSMIT QUEUE. o Press at the transmit queue file defination screen in order to modify the existing transmit queue. o Select transmit queue definition option (4) MODIFY AN ENTRY. o Enter number associated with the last file in the transmit queue in order to modify the CHAIN field. o Press at DO YOU WANT TO CHANGE THE SENDING FILE prompt. o Enter "2" at the TYPE prompt in order to preserve the file transfer mode. o Select "N" at the ENTER CHAIN prompt to modify the parameter in order to prevent the problem. o Select to default through the remaining prompts in order to arrive at the transmit queue defination option menu. 1.

ATP 4.0 requires only the use of the port labelled "ASYNC". On MPx, 13xx, 1500, and 1800 systems, a CCA to modem cable must be connected from the serial port to the "ASYNC" port on the modem. On the 2000 and 3000 systems, the port must be strapped as a "modem" and a standard serial port cable must be connected from the serial port to the "ASYNC" port on the modem. An RJ-11 to RJ-11 cable is supplied with each modem. Plug one end of this cable to the connector labelled "LINE" on the modem, and the other end to the phone line jack. A standard telephone with an RJ-11 connector may be used optionally for manual dialing. Plug the RJ-11 in the connector labelled "PHONE" on the modem. 3.2 27xx/37xx Batch Emulation Package The 27xx/37xx Batch Emulation Package (TBC) supports file transfers between MBF and non-MBF systems using the IBM binary synchronous protocols of 2770, 2780, 3770, and 3780. TBC is available on the BOSS/VS and BOSS/IX systems. The FDX 1200 PLUS and the FDX 2400 PLUS stand-alone units can be configured to run with TBC on BOSS/VS and BOSS/IX systems. In addition, these modems will support the Automatic Dialing feature of TBC on the BOSS/IX systems (2000 & 3000 on 7.3A COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB030 Pg005 and above, 1800 on 7.2N and above). NOTE: The Auto-dial feature of TBC on BOSS/VS systems requires a parallel RS-366, Bell 801 compatible unit. Therefore, the Auto-dial option of the FDX 1200 PLUS and FDX 2400 PLUS are not supported for BOSS/VS systems using TBC. TBC will NOT operate with the 2400 PLUS PC CARD. The FDX 1200 PLUS and the FDX 2400 PLUS are not compatible with Bell 201C or Bell 201C compatible modems. When TBC is used with the FDX 1200 PLUS or the FDX 2400 PLUS, the remote system must also use the identical model. 3.2.1 Modem Configuration Modem strappings for the FDX 1200 PLUS and the FDX 2400 PLUS are identical (except for baud rate) when configured for TBC.

The cable from the synchronous controller port must be connected to the port labelled "SYNC/DATA PUMP". On the MPx systems the synchronous controller port is on the IMLC; on the 2000/3000, CMB port one is the sync port, and on the 1800, the sync port is on the MBF ICC/186 communications controller board. If the Auto-Dial feature of TBC is used on the 2000/ 3000 and 1800 systems, a cable from a serial port on the 4/8 Way must be connected to the "ASYNC" port of the modem. On the 2000/ 3000, the serial port connected to the ASYNC port must be strapped as a 'modem' port. On the 1800, the CCA to modem cable must be connected to the ASYNC port of the modem. An RJ-11 to RJ-11 cable is supplied with each modem. Plug one end of this cable to the connector labelled "LINE" on the modem, and the other end to the phone line jack. A standard telephone with an RJ-11 connector may be used optionally for manual dialing. Plug the RJ-11 in the connector labelled "PHONE" on the modem. 3.3 MAI PC-LINK COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB030 Pg007 MAI PC-LINK is a terminal emulation and file transfer package which runs in the MS-DOS environment on PC/AT systems such as the MBF DS-500 series, the 1500, and the 1800. Once connected to a serial port on a BOSS/VS or BOSS/IX system, MAI PC-LINK will allow the PC to emulate an MBF terminal and additionally transfer files between the systems. The PC may be directly connected or connected via asynchronous modems to the BOSS/VS or BOSS/IX systems.

The 2780 driver will not accept a block of data from a remote system unless the block contains at least two SYN ($32$ EBCDIC, $16$ ASCII) characters between each record in a block. CAUSE: This anomaly is due to a limitation in the CMB hardware and cannot be addressed by a software fix. WORK-AROUND: Re-configure for another terminal type, such as 3780 Standard, on the BOSS/IX and remote systems.

The advantages of using the Paradyne 2030 multiplexer may be summarized as follows: COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB038 Pg001 o Saves money by reducing the number of leased lines or dial-up lines required to support a group of terminal users. o Simplifies a network by reducing the number of modems. o Provides error detection and correction. o Compatible with MBF hosts, terminals and printers. This document complements the Paradyne Installation and Operation Manual and should serve as a guide to users of MBF equipment. 2.0 DESCRIPTION The Paradyne 2030 multiplexer allows error free transfer of a high volume of data between two points. This is accomplished through the use of synchronous modems and error correction. The optional 9600 bps built-in modem is capable of operating over unconditioned 3002 leased lines and uses quadrature amplitude modulation (QAM) with equalization per CCITT V.29 recommendations. Asynchronous channel speeds up to 19.2K bps are supported. Automatic channel speed detection (AUTOBAUD) ranges up to 9600 bps. When an external modem is used the composite link can be clocked from 1.2K bps to 19.2K bps. The maximum channel aggregate is 76.8Kbps, that is, the sum of all the individual channel speeds must not exceed 76.8Kbps. Channel side EIA interface outputs can be forced high or low when in supervisory mode. EIA control signals can also be set to propagate from the local to the remote multiplexer on a per channel basis, refer to Fig.1-5 for the physical and software propagation. Configuration of the Paradyne 2030 multiplexer can be performed using any of the following methods: 1. Front Panel 2. Any channel with supervisory access enabled 3. Dedicated supervisory port A user can configure both the local and remote multiplexer from either end using any of the above methods. Configuration parameters are stored in nonvolatile memory so that in the event of a power loss the multiplexer can resume normal operation when power is restored. When first installing the multiplexer a coldstart should be performed to ensure that Factory Specified Defaults are loaded. For further details refer to the section on Configuration or the Helpful Hints section. The Configuration section also provides all the necessary configura- tion parameters for connecting the multiplexer to SPx, MPx and Advanced Series systems. The Helpful Hints section provides practical information on procedures to follow to ease installation, operation and troubleshooting. 2.1 SETUP AND INSTALLATION 2.1.1 UNPACKING AND SETUP The following section is a step by step procedure taken directly from the Paradyne manual for proper setup of the COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB038 Pg002 multiplexer. If an error occurs in step 5 upon initial power up and persists after resetting call your local MBF branch office or contact MBF corporate headquarters. Note that CTRL V is the default trigger character used to bring up the main menu (SYSTEM MENU). If the menu is not displayed make sure the terminal connected to the Supervisory port is set for the following: 1. Speed 9600 bps 2. 8 Bits/Character 3. No Parity 4. One Stop Bit Once the System Menu is displayed refer to the section on Configuration. The followind lists the procedure for unpacking and setting up the Paradyne 2030. 1. Remove the Paradyne 2030 from the box and place it on a flat surface. 2. EXTERNAL MODEM CONNECTION. Connect the supplied com- posite link to the port labeled COMPOSITE on the rear panel and then to the modem. INTERNAL MODEM CONNECTION. Connect the supplied VF cable to the connector labeled VF on the rear panel and then to the phone line equipment. 3. Connect the customer-supplied RS-232-C cable to the selected port and the DTE, respectively. 4. For Models 2030-11,-12,-13, and -14, plug the female end of the power cable into the receptacle on the rear panel and connect the other end to the power source. For models 2030-01,-02,-03, and -04, connect the cable to the power source. Turn the power switch located on the right side ON. The Paradyne 2030 will automatically adjust to any voltage from 75 to 250 Vac. The unit is operational when the POWER ON LED lights. 5. After the 2030 has been attached to the proper power source it preformes a series of tests to ensure the integrity of the system components. If the tests are passed, the multiplexer LCD displays SYSTEM READY; then the modem LCD displays the default settings, and the system configuration can be preformed. If the tests are failed, the LCD displays a message (refer to System Error Messages section). When this message is displayed cycle the power. If the error occurs again contact your Paradyne service represenative. 6. Connect a standard ASCII terminal, if used, to the 2030 using customer-supplied, straight-through, RS-232-C I/O cable at the port labeled SUPERVISORY. NOTE: Shielded RS-232-C I/O cables are required for Models 2030-01,-02, -03, and -04. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB038 Pg003 Connect the terminal to the power source and turn on the terminal. PRESS: (default = CTRL +V) System Menu is displayed. Check the following items if System Menu does not appear. o Terminal cabling. o Terminal power on switch ON. o Terminal speed 9600 (refer to terminal manual). o Multiplexer supervisory enabled parameter SET to YES (refer to Chapter 2) o Multiplexer is decimal 022 (default = CTRL + V) (refer to Chapter2) o Multiplexer stop bits (refer to Chapter 2). o Multiplexer parity (refer to Appendix D). For additional information on these items refer to the indicated chapters. MULTIPLEXER The multiplexer is configured at the factory with a set FACTORY of default parameters. Refer to Tables 1-1 and 1-2 for DEFAULTS default settings. If you want to change any of the multiplexer parameters, refer to the appropriate paragraph in Chapter 2. 2.1.2 CABLING The multiplexer is supplied with a cable to connect the composite link to an external modem if an internal modem was not ordered. If an internal modem is ordered two RJ11 voice frequency (VF) connectors are supplied, one is used internally to connect the modem board to the internal VF connector, the other is used to connect the external VF connector to the phone line equipment. Channel side cabling will depend on application. Typically a so called "straight-through cable" or "pin-to-pin" cable may be used to connect the multiplexer as shown in Fig. 1-1 and Fig. 1-2 in the Application Examples section. The actual pinouts of the MBF cables used in the Application Examples appear in Section 2.1.2.1. The following is a listing of the typical MBF cables used to connect the Paradyne 2030 multiplexer to MBF hosts and peripherals. Notice that cables with the same part number may appear twice. The part number only identifies a cable's pin configuration. The market code, however, specifically identifies the cable as to length and description in addition to its pin configuration.

The 907648 cable is used to connect the multiplexer to the backpanel of MPx and Advanced Series systems using DB15 connectors. The 907117 cable must be used when connecting directly to 4/8-way boards. 3.0 MULTIPLEXER CONFIGURATION This section provides the user of MBF equipment with all the necessary configuration parameters for connecting the Paradyne 2030 multiplexer to SPx, MPx and Advanced Series systems. Multiplexer configuration can be broken down into two basic parts, hardware and software configuration. Hardware configuration is normally factory-set and should only be modified for testing and troubleshooting. Software configuration of the multiplexer allows it to be compatible and interface with a wide range of hosts and peripherals. Software configuration tables are included for SPx systems running BOSS/IX and MPx and Advanced Series running BOSS/VS operating systems. All the software configuration tables are based on a local mux connected to a host port and a terminal or printer. Configuration parameters may be entered using the front panel, however using a terminal attached to the Supervisory port or any channel enabled for supervisory access is faster and easier. 3.0.1 HARDWARE CONFIGURATION Refer to section H in the Paradyne manual titled "Factory Hardware Options Settings" for hardware configuration of the multiplexer and modem assemblies. Normally these switch settings and straps do not need to be changed. However, for test and basic troubleshooting purposes this section can prove to be quite helpful. When testing the multiplexers back-to-back, for example, the transmit power output of the built-in modem must be cut back to -14dBM. Table H-1 in Modem Configuration Options indicates how S7 must be changed from the factory default value of 0dBM. 3.0.2 MULTIPLEXER AND MODEM FACTORY DEFAULTS The multiplexer has a set of Factory Default parameters COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB038 Pg006 permanently stored in Read Only Memory (ROM). These default parameters are loaded when a coldstart is performed. Factory defaults should be used whenever possible in order to minimize configuration effort. The following section lists all the factory default settings for the multiplexer and the built-in modem.

A coldstart can only be initiated from the front panel using the following procedure: 1. Put the multiplexer into monitor mode by pressing the right hand touch panel until the LCD displays shows Monitor Mode. 2. Press the SELECT key and hold it down while pressing the NEXT key. The LCD display will show SYSTEM READY and a time of 00:00:00 after a successful coldstart. Note that toggling the power switch ON/OFF will only perform a warmstart, the multiplexer will not revert to the factory- set defaults. o When logging on to the Supervisory for the first time ensure the terminal used is set to the Supervisory port defaults, that is, 8 Bits, No Parity, One Stop Bit and a Speed of 9600 bps. The terminal set up on MBF terminals must be changed COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB038 Pg017 since their defaults are 7 Bits, Odd parity, and One Stop Bit. The Supervisory port can be preset to MBF defaults by a two step procedure: 1. Select SET SUPERVISORY PARAMETERS off the main menu and set DATA BITS to 7. Then set the terminal to 7 BITS. 2. Select SET SUPERVISORY PARAMETERS again and set PARITY to ODD. Then set the terminal to ODD PARITY and do a SAVE. Reset the terminal or power the terminal OFF then ON. o Exceeding the maximum channel aggregate of 76.8kbps may cause data loss. To avoid this possibility make sure the sum of all channel speeds are below 76.8kbps. o If dialbacker operation is required an external dialbacker unit must be connected to the Paradyne 2030 multiplexer. If the multiplexer is equipped with the internal modem tlhen S7 posit- ions 1,3,4,5 on the modem board may require changes from the factory default settings. Refer to Section H in the Paradyne 2030 manual for suggested switch settings when connecting to dial lines. o CAUTION: Some customers may have built their own cables. These cables may not be suitable for connecting the multi- plexer since they were made for a customer's specific applic- ation. Do not depend on customer built cables. Make certain the proper MBF cables are used or that custom built cables are wired as shown in the MBF Cable Pin Configurations in Section 2.1.2.1. o CAUTION: On SPx systems ensure that the 4/8-way or the CMB port used to connect to the multiplexer is jumpered for connect- ion to a modem. All the cabling recommendations in this document assumes SPx ports are jumpered for connection to a modem. 5.0 TECHNICAL SPECIFICATIONS POWER SUPPLY 110/220 Vac 50/60 Hz .2A without modem .3A with modem HEAT DISSIPATION 68 Btu/hr without modem 85 Btu/hr with modem ENVIRONMENT Operating Temperature: 32 F (0 C) to 113 F (45 C) Storage: -4 F (-20 C)to 158 F (70 C) Relative Humidity: 5% to 90% DIMENSIONS Hight: 3-7/8 in.

The modem is compatible with MBF host communication packages, terminals and PCs. The features of the DM424 may be summarized as follows: o Runs in asynchronous and synchronous data modes. o Operates over dial lines or 2-wire leased lines. o Allows for easy option configuration using "AT" commands. o Supports an extended Hayes "AT" command set that is not only compatible with the original "AT" command set, but includes additional commands for error correction, speed conversion, security, and stored numbers for autodialing. o Features DTE speed conversion. This allows a host, terminal or PC to run at a fixed speed for all incoming calls. o Supports up to MNP Class 5 error detection/correction providing error free asynchronous communications. o Features Trellis Coding, a DTE transparent forward error correcting protocol in V.32 mode. o Compatible with the following MBF communication packages: 1. ATP 4.0 2. TBC 27XX/37XX Emulator, Autodial not supported 3. BOSS/VS 3270 BSC 4. X.25 WAN for FTF or MAGNET/FTF 5. MAI PC-LINK 6. BOSS/VS TERM Terminal Emulator 2.0 DESCRIPTION The DM424 modem is designed for easy installation and operation. Ensure that a proper dial line or 2-wire leased line is available for connecting the modem. In addition ensure that the wall mount transformer supplied with the modem matches the line voltage (110/220 VAC) for your site. NOTE: Do not attempt further installation if the wrong wall mount transformer was supplied. 2.1 INSTALLATION When unpacking the DM424 modem, check to see that the following items are included: COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg002 1. The DM424 standalone modem 2. Owner's Manual 3. One telephone line cord with RJ-11 connectors at both ends 4. One wall mount transformer To proceed with the installation of the DM42make sure the power switch on the back on the unit is in the OFF position and perform the following: 1. Plug the RS-232 cable coming from the host or terminal into the connector at the rear of the modem labeled DTE. 2. Plug the optional telephone set into the RJ-11 connector labeled "TELSET". 3. Plug the telephone line coming from the wall jack into the connector labeled "TELCO". 4. Plug the wall mount transformer into a proper electrical outlet and then into the power receptacle labeled "PWR". Turn the power switch ON and observe the front panel lights. The MR light should be ON solid. If the MR light blinks at power-up the self-test has failed and you should call your local MBF branch office or contact MBF corporate headquarters. 2.1.1 CABLING There is only one RS-232 cable that connects the DM424 modem to a host or terminal. The right cable to use usually depends on the host and the app~rlication. Refer to Application Examples Section 4.0.1 and then to Cabling Diagrams Section 2.1.1.1 to select the proper MBF cable. When the DM424 is connected to a terminal only a minimum number of pins (PINS 2,3,7,20) are commonly used. Refer to MBF Cable Pin Configurations Section 2.1.1.2 if you are making your own cable. NOTE: MBF RS-232 cables are not supplied with the modem and must be ordered separately. Order the proper cable for your system. The following is a list of Market Codes for cables to be used when connecting the DM424 modem to MBF systems.

These indicators are used to provide the user with the modem's status in both command and data mode operation. The definition of each LED is as follows: MR - The "modem ready" LED will come on at power-up. If it blinks at power-up, it means the self-test failed and you should call your supplier or service represent- ative. The "MR" LED also blinks during test modes. TR - This is the "terminal ready" (DTR) indicator. It displays the status of DTR. This must be on for the modem to dial or answer. The default is for normal RS-232 DTR, however this may be forced on with the AT&D0 command. CD - This LED displays the "data carrier detect" (DCD) status. This comes on when the modem has completed the handshake and is ready for data. The default is "forced on". It may be set to normal with either the AT&C1 command or by the rear dip switch (SW 3). SD - The "send data" LED flashes when a character is being sent to the modem from the terminal. RD - The "receive data" LED flashes when data is being sent to the terminal from the modem. HS - The "high speed" LED is turned on only when the modem is operating at 9600 bps. AA - The "auto-answer" LED is turned on when the modem is set up to auto-answer calls. This LED flashes during an incoming ring. OH - The "off-hook" indicator is turned on when the modem goes off-hook. Front Panel Answer/Originate Switch Located on the front panel of the modem is a left/right toggle switch, labeled "A" and "O". This switch provides the user with the ability to switch between "talk" mode and "data" mode. When the modem is in the idle state of "offline", the user can use the telephone connected to the "TELSET" to place voice calls. While connected to a voice call the user can switch that call to a data call simply by toggling the switch to either the "O" or "A" position. The remote user must also force their modem into data mode by toggling the switch to the opposite position. The modems will then connect and should be able to pass data. Further, if the users wish to switch back to "talk" mode, they must first place the connected telephone "off-hook", and then COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg006 one of the users must toggle the switch in the "O" or "A" direction. The "A" or "O" switch provides three basic functions: Force Originate (O) Toggling the switch toward the "O" direction while in idle mode forces the modem in the originate handshake. This means that if a call is manually dialed using a telephone connected to the "TELSET" jack, the user can then toggle the switch towards the "O" direction and the modem will then try to connect to the remote modem. This is particu- larly useful when there is no asynchronous DTE device available for dialing. Force Answer (A) Toggling the switch toward the "A" direction while in idle mode forces the modem into the answer handshake. This enables the call to be manually answered. Disconnect (A OR O) While in data mode or in a test mode, if the switch is toggled in either the "A" or "O" direction, the modem will disconnect. This means that two users who are connected to each other in data mode can switch to "talk" mode and use a telephone connected to the "TELSET" jack. Both users after picking up their telephone will be able to talk if one side toggles the front panel switch. 2.3 DIP SWITCH SETTINGS There is only one four-position Dip Switch located at the rear of the modem. The default setting is all switches in the "off" or "up" position. DIP SWITCH DEFINITION ______________________________________________________ | Switch | ON (Down) | OFF (Up) | | | | | | 1 | MI/MIC enabled | MI/MIC disabled | | | | | | 2 | Dumb Mode enabled | Dumb Mode disabled | | | | | | 3 | DCD Forced enabled | DCD Normal RS-232 | | | | | | 4 | External Sync Clk | Internal Sync Clk | |_________|_____________________|______________________| SW1: MI/MIC refers to a call origination method used by some PBX systems where pins 2 and 5 of the RJ-11 connectors on the rear of the modem are sorted together and then opened. This will force the modem to look for an answer sequence from a remote modem. Normally this feature is disabled. SW2: Dumb Mode enabled is very useful for auto-answer only applications where a host will not send any AT commands to the modem or expect any response messages back from the modem. Dumb mode can also be enabled for some COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg007 synchronous applications where a polling pattern may abort auto-dialed calls. In this case calls must be manually dialed. Dumb mode is disabled by default since the modem will not respond to AT commands from the DTE when in Dumb mode. NOTE: When connecting the modem for auto-answer only to SPx systems with a start process configured for the port, be sure to enable Dumb Mode; set DIP SW2 down. SW3: DCD Forced on switch will force pin 8 high to the attached DTE. Normally it is desirable to have DCD follow true carrier, therefore, SW3 is disabled by default. Some applications, however, may require DCD to be high all the time. SW4: External Syn Clk switch, when enabled, is useful in tail circuits and more complex networks that require the use of an external clock source. The modem will provide a TXCLK (transmit clock) and RXCLK (receive clock) on pins 15 and 17 respectively when set for Internal Syn Clk. Normally in simple point-to-point synchronous communications the modem provides the clock and therefore, the default is Internal Syn Clk. NOTE: The DM424 modem only reads the Dip Switch at power up. If any Dip Switches are changed, turn the modem OFF and then ON for the changes to be recognized. When "dumb mode" is enabled, all result codes and AT commands are disabled. 3.0 BASIC OPERATION The DM424 modem utilizes the generally accepted industry standard HAYES AT command set with some exteions that are unique to the xDDM424. There are two basic operational modes for the modem: 1. IDLE mode - when not connected to another modem. 2. DATA mode - when the modem is connected, "online", to another modem. COMMAND Mode is a submode of the above and can be entered while IDLE or in DATA mode. In COMMAND Mode the modem will accept and respond to AT commands. The AT commands recognized by the DM424 fall into three catagories: 1. "AT", "AT&" or "at", "at&" + < command body > + This is the{standard Hayes AT command set. 2. "A/" or "a/" This causes a repeat of the last command stored in the 40 character command buffer. This is very convenient for redialing a number that was not entered into nonvolatile memory. 3. +++ This command is the default escape sequence which is used when the modem is in DATA mode and you want to put it in command COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg008 mode. The command "ATO" will return the modem to data mode. For a complete listing of AT commands and their function refer to the ARK DM424 Installation and Operation Manual. A summary of AT commands showing defaults appears in the next section 3.1. When the DM424 is in IDLE mode each time an AT command is entered it will analyze the prefix "AT" or "at" for speed and parity and will train itself to match the speed of the DTE. NOTE: The modem will only accept DTE speeds of 1200, 2400, 4800, 9600, and 19,200 bps. Speed conversion, which is enabled by default, allows the DTE to remain at a fixed speed for all incoming calls. The format of each character in an AT command must be a 10-bit ASCII code in only the following combinations: Case Start Bit Data Bits Parity Stop Bits = 10 bits 1 1 + 7 + 1 + 1 = 10 bits 2 1 + 8 + 0 + 1 = 10 bits 3 1 + 7 + 0 + 2 = 10 bits NOTE: Only Case 1 allows for even, odd, mark or space parity. 3.1 AT COMMAND DEFAULTS AT COMMAND DEFAULT DESCRIPTION ATA Answer an incoming call ATD Dial a number ATE E1 Echoing of commands is enabled ATH Go "on" or "off" hook ATK K1 Break is enabled during MNP mode ATL L2 Speaker volume is medium ATM M1 Speaker is on during handshake only ATO Force "originate" or go back online ATQ Q0 Status messages are enabled ATS Read or write to the S-registers ATV V1 Messages are sent in the verbose form ATX X4 The "CONNECT XXXX" message is sent and dial/busy tones are detected ATZ Reset command AT&B B0 DSR is forced on AT&C C1 DCD follows normal RS-232 AT&D D2 DTR follows normal RS-232 AT&F Set modem to factory defaults AT&H H1 Leased line auto-handshake is enabled AT&L L0 Dial-up line is selected AT&M M0 Asynchronous mode is enabled AT&R R2 CTS is forced to always on AT&S Display stored numbers AT&T T4 Test mode commands, grant response to RDLB COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg009 AT&W Write configuration to memory AT&Z Store telephone numbers to memory _____________________________________________________________________ AT*A A0 Reverse answer command disabled AT*D D0 Character length is 10 bits AT*E E1 Error control is auto-reliable (MNP5) AT*F F2 XON/XOFF flow control is enabled (modem control) AT*O Display option settings AT*P P0 User abort control is enabled AT*Q Q1 Signal Quality Action is retrain AT*S S1 Speed conversion is enabled AT*T T1 Trellis coding is enabled AT*U U0 Access security is disabled 3.2 DIALING A CALL The DM424, when in IDLE mode, will accept an "ATD" command sequence from the DTE and will proceed to go "off-hook" and dial a specified number. The modem will then attempt to establish a connection at the detected DTE speed. If, for example, the modem is given the following command sequence "ATDT 1-714-731-5100" at 9600 bps it will attempt to establish the connection at 9600 bps, however, it will automatically switch to 4800, 2400, or 1200 to accommodate the speed of the remote modem. A typical auto-dialing command from an office with a PBX system is as follows: >ATDT 9,1-(714)-731-5100 When the modem receives this command it will go "off-hook" and wait 2 seconds by default for a dial tone. If there is no dial tone within the time specified in register S6 the modem will go "on-hook" and return a "NO DIAL TONE" message. When a continuous one second dial tone is detected, the digit 9 will be sent out as a dialed numeral. The modem will then pause for a time specified in register S8 (2 sec default) before dialing the rest of the digits. The modem will then wait for an answer tone from the remote modem for the duration specified in register S7 (45 sec default). When handshaking is completed the agreed upon data rate will be displayed as a message "CONNECT 9600 EC" for example. If the remote modem is busy, the modem will go "on-hook" and return a "BUSY" status message. If the modem is unable to complete an acceptable handshake within the time specified in register S7, it will drop the line and return a "NO CARRIER" status message. For a complete explanation of dial modifiers and S-Registers refer to the ARK DM424 Installation and Operation Manual.

The next time you wish to dial that number you can do so easily and automatically from memory. There are three commands related to "prestored number dialing". 1. AT&Z To store a number 2. AT&S To display the numbers(s) stored 3. ATDS To dial a prestored number The AT&Z command will allow you to store the phone numbers in nonvolatile memory. Each memory location can store up to 32 digits or characters including carriage return and dial modifiers. The AT&S command allows you to display the ten stored numbers in nonvolatile memory. The ATDS command will automatically dial a prestored number. Example: >AT&Z3: T91-212-756-9866,4327 to store the number in directory location #3. Modem Response: OK AT&S - To display the number #1: T73517 #2: 1224 #3: T91-212-756-9866,4327 #4: T7788113 COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg011 #5: ABC #6: T7271277 #7: T4087676767 #8: #9: #10: T4321876 Modem Response - OK >ATDS3 - to dial out the number in location #3 It should now be quite clear just how to use the "pre- stored number dialing" command. The possible commandD entries are summarized below: ATDS1 Auto-dial location 1 ATDS2 Auto-dial location 2 ATDS3 Auto-dial location 3 ATDS4 Auto-dial location 4 ATDS5 Auto-dial location 5 ATDS6 Auto-dial location 6 ATDS7 Auto-dial location 7 ATDS8 Auto-dial location 8 ATDS9 Auto-dial location 9 ATDS10 Auto-dial location 10 3.3 ANSWERING A CALL The DM424 modem has built-in "ring detection" circuitry that provides the capability to automatically answer an incoming phone call. The contents of the S-register "S0" determines when this feature is enabled. If S0=0, then the auto-answer feature is disabled and the DM424 modem will not answer under any condition. If the value of S0 is between 1 and 255, the modem will count the rings and send out a "RING" message for each ring counted. Once the ring counts equal the value specified in S0, the DM424 modem will go off-hook, remain silent for 2.1 seconds, then send out an answer tone. Both modems will begin the handshaking at this point and continue until they enter the Data mode or recognize that they are not compatible. NOTE: If the value if S0 is too large, the originating modem might give up and drop the line before the answering side sends out an answer tone. This is because the originating side usually will not wait more than 45 seconds for an answer tone. The originating modem's answer tone wait period, after the dial sequencer, is determined by S-register 7. Manual Answer (ATA) In some situations the manual answer capability is required. One example is to eliminate the possibility of the modem automatically answering long-distance calls while you or the attached system are not available. There are two typical applications for using the manual answer feature. 1. When the "auto-answer" option has been selected and there is an incoming call, you can key in ATA before the modem answers the call. By doing this, the modem will ignore the ring count, wait 2.1 seconds, COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg012 then send out an "answer tone" and start the handshaking sequence. 2. When the modem is in idle mode and you key in ATA, the modem will wait for 2.1 seconds (the so-called "billing delay") then send out an "answer tone" and look for a handshaking sequence from the originating modem. If the data mode has not been entered within 45 seconds (or the S7 setting), the modem will drop the line and return a "NO CARRIER" message. In this applic- ation, the remote side should prepare for manual origination. NOTE: The ATA command is only accepted when the modem is in idle mode. 3.4 DISCONNECTING A CALL When data transmission has been completed, you may wish to disconnect from the telephone line and terminate the call. There are a number of ways this can be done. They are as follows: 1. THE ATH COMMAND You can always disconnect by first going into command mode with the >+++ command, and then after the modem returns >OK you may enter the >ATH command and the modem will be disconnected. It will again show the >OK response and will then be in the idle mode, ready to accept new commands. 2. LOSS OF DTR The AT&D2 and the AT&D3 commands configure the modem to disconnect after losing DTR. The AT&D3 command will force the modem to disconnect after losing DTR, then load the prestored, nonvolatile options. 3. LOSS OF CARRIER If a loss of carrier is detected for a time greater than that specified in the S10 register, the DM424 will disconnect immediately and return a "NO CARRIER" message. If S10=255, disconnect on loss of carrier is disabled. 4. POOR SIGNAL QUALITY If poor signal quality is received and the Signal Quality Action is set for disconnect (i.e., AT*Q3), the DM424 will disconnect and return a "NO CARRIER" message. 5. FRONT PANEL SWITCH Toggling the front panel switch in either the "A" or "O" direction during a connection will cause the call to disconnect. This will also end the ALB (Analog Loopback) test mode. 3.5 SYNCHRONOUS OPERATION COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg013 The modem has two basic operational modes, synchronous and asynchronous. The modem can be set up to operate in various combinations of command and data modes using synchronous or asynchronous formats. The AT&M command selects the format and data mode. When operating in synchronous data mode, no start or stop bits are required. Instead a transmit and receive clock are responsible for synchronizing data flow. Most synchronous computer terminals (DTEs) require the following RS-232 set-up: DCD Data carrier detect should be set to "normal RS-232" with the AT&C1 command. This is the default. CTS Clear-to-send should be set to follow DCD with the AT&R1 command. This is not the default. DSR Data set ready should be set to follow DTR with the AT&B1 command. This is not the default. DTR Data terminal ready should be set to "normal RS-232" with the AT&D2 command. This is the default. NOTE: When synchronous mode operation is enabled, the MNP (Microcom Networking Protocol) error correction, flow control, and speed conversion option are disabled. Dumb Mode Many synchronous devices do not wish to receive or send any of the standard "AT" commands or result codes which are sent in an asynchronous format. These devices are also often configured to constantly transmit synchronous polling patterns that can abort auto-dialed calls as specified in the AT*P command. It is for these reasons that the "dumb mode" Dip Switch is most useful. When Dip Switch 2 is in the down position, the modem is configured for "dumb mode" and will not transmit or receive any data over the RS-232 until carrier has been established and the modem is "online". 3.6 LEASED LINE OPERATION The DM424 is capable of operating over private 2-wire leased line networks. The leased line transmit level is -2 dBm or -10 dBm. To set your modem up for 2-wire leased line mode, you must follow these instructions: a. Plug the leased line cable into the receptacle in the back of the modem labeled "TELSET". b. Give the AT&L2 or AT&L4 command to the modem to select the 2-wire leased line mode. c. Use the AT&H command (AT Commands section) to enable or disable the automatic leased line handshake feature. When enabled the modem will automatically try to re-handshake after being disconnected. This is the factory default. If this feature is disabled, then after each leased line disconnect, the handshake must be manually reinitiated. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg014 d. Each modem in the leased line link must be designated as either the originate modem or the answer mode. This can be done by enabling auto-answer with an ATSO=1 command to select answer or disabling auto-answer with the ATSO=0 command to select originate mode. e. Finally, both modems must have the handshake initiated. This is done by using the ATO and ATA command for originate and answer respectively. 4.0 MODEM CONFIGURATION WHEN CONNECTING MBF EQUIPMENT 4.0.1 APPLICATION EXAMPLES NOTE: See diagram in Cabling Examples Section 2.1.1.1 The diagram shows the DM424 modem in typical applications when connected to MBF equipment. The following describes how the modem can be used for each application. ATP: ATP 4.0 can utilize modem A to call modems G and I to perform asynchronous file transfer. TBC: TBC 27XX/37XX Emulator will use modem C to call the IBM host which has another vendor's V.32 modem. Modem C can also call modems H and J and run TBC. 3270 BSC Emulator and TBC must use different IMLC ports. 3270: BOSS/VS 3270 BSC Emulator can use modem C to connect to the IBM host to perform interactive 3270 communications. TBC and 3270 must be on separate IMLC ports. WAN: X.25 WAN can use modem D and E on a leased line to send files via FTF or Magnet. PC-LINK: A PC running MAI PC-LINK can use modem K to call modem F. The user can then logon to the MPx/AS system as if locally attached and proceed to exchange files. TERM: The BOSS/VS Terminal Emulator (TERM) allows asynchronous outdial from any terminal on an MPx/AS system. A user can have TERM send commands to modem B to dial the HP host which uses another vendor's V.32 modem. 4.1 ATP 4.0 The Asychronous Transport Package (ATP) is an asynchronous intersystem file transfer program which allows MPx, SPx, GPx systems as well as the 13XX and MAI 1500 to exchange files. ATP 4.0 provides autodialing and autoscheduling capabilities. This allows sessions to be run unattended. The DM424 modem requires minimal configuration for running ATP. The required port configuration to run ATP 4.0 on your system appears in the Intersystem Transport Package (ITP) User Guide M6354. Follow the recommended configuration for your specific system carefully. To setup the DM424 modem for running ATP 4.0 perform the following on both the local and remote modems: COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg015 1. To ensure the DM424 is properly initialized with factory defaults, connect a terminal to the DTE port and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATZ >OK 2. Set the Dip Switch: SW 1 2 3 4 Up Up Dn Up 3. Power the modem OFF and then ON. 4. Connect the recommended MBF cable to the DTE port of the modem. NOTE: ATP 4.0 will send additional AT commands to the modem for setup and dialing. The DTE speed must be the same on both ends of the link and can range up to 19,200 bps. 4.2 27XX/37XX BATCH EMULATOR The 27XX/37XX Batch Emulator (TBC) uses IBM's bisync (binary synchronous) protocol to perform file transfer between MBF and non-MBF hosts. The DM424 modem in synchronous mode can be used for linking two sites for running TBC. For proper configuration of your system to run TBC refer to the BOSS/IX, BOSS/VS or BOSS/VX TBC User manuals listed in Section 11. To setup and configure the DM424 for running TBC do the following: 1. Connect a terminal to the DTE port and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATZ >OK >AT&B2&R0 >OK >AT&M3&W >OK 2. Set the Dip Switch: SW 1 2 3 4 Up Dn Up Up 3. Power the modem OFF and then ON. 4. Connect the recommended MBF cable to the DTE port of the modem. Manually dial the remote site and after hearing the answer tone immediately switch to Originate (O) using the front panel toggle switch. This will allow the modems to complete the handshake. NOTE: The DM424 modem, when set for TBC, has Dumb mode enabled to ensure synchronous polling will not effect COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg016 its operation. The command AT&M3 puts the modem in a synchronous mode where the number must be manually dialed with a phone connected to the "TELSET" jack. TBC autodial is not supported when using the DM424 modem. 4.3 BOSS/IX/VS 3270 BSC EMULATOR The BOSS/IX/VS 3270 BSC Emulator Package emulates an IBM 3271-2 cluster controller and provides remote interactive communications between IBM (or equivalent) hosts and MBF systems. The DM424 modem can be setup for synchronous operation and be used to link two sites for running 3270 BSC. The modem setup and configuration is identical to that for running TBC. For proper configuration of your MBF host, refer to the BOSS/IX or BOSS/VS 3270 BSC Emulator Package User Reference Manual listed in Section 11. To setup and configure the DM424 for running 3270 BSC do the following: 1. Connect a terminal to the DTE port and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATZ >OK >AT&B2&R0 >OK >AT&M3&W >OK 2. Set the Dip Switch: SW 1 2 3 4 Up Dn Up Up 3. Power the modem OFF and then ON. 4. Connect the recommended MBF cable to the DTE port of the modem. NOTE: The DM424 modem has Dumb mode enabled to ensure synchronous polling will not effect its operation. The number must be manually dialed with the &M3 synchronous mode. 4.4 X.25 WAN COMMUNICATIONS The MBF network communication products, File Transfer Facility (FTF) and Magnet, provides for file transfer and record level data access respectively between MBF computer systems using LAN or WAN media. Using X.25 WAN communi- cations the DM424 modem in synchronous mode can be used to link two sites for running FTF or Magnet. The modem setup and configuration is identical to that for running TBC. For proper configuration and operation of FTF or Magnet to run on your system refer to FTF BOSS/IX/VS User Reference manuals or to Magnet BOSS/IX or BOSS/VS User Reference manuals listed in Section 11. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg017 To setup and configure the DM424 for running X.25 WAN communications do the following: 1. Connect a terminal to the DTE port and enter the following commands: >AT&F&W >OK MODEM RESPONSE MESSAGE >ATZ >OK >AT&B2&R0 >OK >AT&M3&W >OK 2. Set the Dip Switch: SW 1 2 3 4 Up Dn Up Up 3. Power the modem OFF and then ON. 4. Connect the recommended MBF cable to the DTE port of the modem. NOTE: The DM424 modem has Dumb mode enabled to ensure synchronous polling will not effect its operation. The number must be manually dialed with the &M3 synchronous mode. 4.5 MAI PC-LINK MAI PC-LINK provides terminal emulation and file transfer capabilities for PC/AT systems in an MS-DOS environment. The DM424 modem may be used to connect a PC running PC-LINK to an MBF system running BOSS/VS, BOSS/IX or BOSS/VX. Refer to the PC-LINK User Guide M6340, for details on configuration and operation. The DM424 setup and configuration is as follows: 1. Start PC-Link and go into Terminal Emulation. 2. Connect the modem using the recommended MBF cable to the COM port setup in PC-LINK. 3. Make sure the Dip Switch has all switches in the "off" or "up" position. 4. Turn the modem OFF and then ON if Dip Switches were changed. 5. Enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATZ >OK 6. If you entered a phone number when configuring PC-LINK, the modem should dial out at this point using the default modem setup defined in PC-LINK. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg018 4.6 BOSS/VS TERM TERMINAL EMULATOR TERM is a terminal emulator that allows terminals connected to BOSS/VS systems to connect transparently with remote MBF and non-MBF hosts. The DM424 modem can be connected to a TERM host target port or to a remote terminal port. Ports that are designated TERM host target ports should only be used for outdial using TERM. These ports should not be used for dial-in and, therefore, auto-answer is disabled. For proper port configuration for your system, refer to the BOSS/VS Terminal Emulator User Guide M0176. To configure the DM424 for connection to a TERM host target port do the following: 1. Ensure that all Dip Switches are in the "off" or "up" position. 2. Connect a terminal to the modem and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATS0=0 >OK >AT&W >OK 3. Turn the modem OFF and then ON. 4. Connect the recommended MBF cable between the host and the DTE port of the modem. To configure the DM424 for connection to a TERM remote terminal port do the following: 1. Connect a terminal to the modem and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATZ >OK 2. Set all switches "off" or "up" on the Dip Switch. 3. Power the modem OFF and then ON. 4. Connect the recommended MBF cable between the host and the DTE port at the modem. 4.7 REMOTED MBF TERMINALS This section will describe the necessary configuration of MPx, SPX and GPx ports for communicating with remote term- inals using the DM424 modem. The modem configuration for the host end will normally have echo and result codes disabled. If the modem at the host end is to be used for auto-answer only, then it is recommended COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg019 that Dumb mode be enabled, Dip Switch 2 down. The remote side modem configuration normally would have echo and result codes enabled. The DM424 factory defaults should work in most cases. The factory defaults may be loaded by entering the command >AT&F&W. The following pages have the port configurations for MPx, SPx and GPx systems when linked to remote MBF terminals with salve printers. To set up and configure the DM424 modem for linking an MBF host to a remoted MBF terminal do the following: On the MBF host end: 1. Connect a terminal to the DTE port of the modem and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG >ATZ >OK 2. Set the Dip Switch SW 1 2 3 4 Up Dn Up Up 3. Power the modem OFF and then ON. 4. Connect the recommended MBF cable to the DTE port of the modem. 5. Configure your host port as shown in the following pages. On the Remote end: 1. Connect a terminal to the DTE port of the modem and enter the following commands: >AT&F&W >OK MODEM RESPONSE MSG. >ATZ >OK 2. Make sure the Dip Switch has all switches in the "off" or "up" position. 3. Turn the modem OFF and then ON if the Dip Switches were changed. 4. Connect the recommended MBF cable between the terminal and modem. 5. Set up terminal configuration using the following pages as a guide.

For the receiving modem send "ATSO=1" to set it in autoanswer mode. The sending modem is now ready to dial, use the "ATDT"+phone number to start the session. 5.0 MNP ERROR CORRECTION The DM424 modem comes with the Microcom Networking Protocol (MNP) error detection/correction capability. When the error control mode is enabled, and if the remote modem also supports MNP, then this protocol ensures error free data transmission. This means even COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg026 with poor quality telephone lines asynchronous data transfer will be error free. The DM424 modem supports MNP classes 2,3,4, and 5. While all of the classes provide error-free transmission, classes 4 and 5 also provide added throughput. This means if the DTE rate is set for 19,200 bps and both modems have MNP enabled, then the net through- put could be as much as 2 times the connection speed. Example: The DTE is set for 19,200 bps. A connection is made to a DM424 where the DTE is also set for 19,200 bps. The modems connect at 9600 bps, but using the MNP feature and XON/XOFF flow control, the actual data throughput for this particular file type is 19,200 bps. While it is certain that the MNP compression used in this modem will enhance the throughput of your modem, the compression ratio is dependant upon the "type" of data being transmitted, and there- fore, the exact "net" increase in speed cannot be determined. It is very useful to use the speed conversion feature to provide your system with maximum performance. The DM424 is shipped with MNP error control enabled (AT*E1) as the factory default. The MNP option is controlled with the following commands: AT*E0 MNP disabled AT*E1 Auto-reliable MNP5 enabled (default) AT*E2 Reliable MNP5 enabled AT*E3 Auto-reliable MNP4 enabled AT*E4 Reliable MNP4 enabled Auto-reliable MNP mode causes the modem to try to connect with the remote modem using MNP, but if the remote modem does not support MNP, then a non-MNP connection is established. Reliable MNP mode forces the modem to connect with MNP. In this mode the modem will only connect if the remote modem also supports MNP, otherwise the modem will not connect. After the modem has established a connection, a CONNECT XXXX message will be sent to the screen, where the XXXX is the connection speed, i.e. "CONNECT 9600". If an MNP connection is also established, then the response will be CONNECT XXXX EC The EC message indicates that MNP is active. The AT*M0 command can be given to the modem to disable error control result messages if the "EC" message is not desired when error control is on. In answer mode, the modem will try for 5 seconds to connect with MNP before falling back to a non-MNP connection in auto-reliable mode, or disconnecting if in reliable MNP mode. NOTE: During error control mode, all test modes are disabled. MNP is supported at connection speeds of 9600, 4800, 2400, and 1200 bps. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg027 6.0 SPEED CONVERSION The DM424 modem provides a DTE speed conversion feature that allows your host or PC to run at a fixed speed for all incoming calls. This means that a 1200, 2400, or 9600 modem can connect to your host terminal or PC without changing the baud rate, as long as the fixed rate is at least as high as the highest rate you want to support. In this case, that would be 9600 baud. By using "flow control", the modem will buffer, or "pace", the flow of data between the modem and RS-232 interface. This means that the baud rate for the DTE port can be set for up to 19,2000 bps and the speed of the data link over the line can go as low as 1200 bps and the modem will send data in bursts to and from the computer at a rate of 19,200 bps. The commands to enable and disable this feature are: AT*S0 disable speed conversion AT*S1 enable speed conversion (default) Flow Control To set up the speed conversion feature, you must first be sure that the modem and terminal are using the same type of flow control. The DM424 supports the following flow control commands. AT*F0 disable flow control AT*F1 XON/XOFF (passthrough) AT*F2 XON/XOFF (default) AT*F3 CTS flow control AT*H0 Disable ENQ/ACK AT*H1 Enable ENQ/ACK DISABLED - No flow control is used (DTE rate must be the same as the connection rate). XON/XOFF PASSTHROUGH - The modem sends an "XOFF" character to the DTE when it wants the DTE to stop sending data, and sends an "XON" character to the DTE when it wants the DTE to continue sending data. If the modem should receive an "XON" or "XOFF" from the DTE, it passes it through as data to the remote modem. XON/XOFF - The modem sends "XON" and "XOFF" characters to the DTE to control the flow of data to the modem, and also accepts the "XON" and "XOFF" characters from the DTE to control the flow of data to the DTE. RTS/CTS - RTS and CTS are RS-232 pins that can be used as a form of hardware flow control. When the RTS pin from the DTE to the modem goes low, the data flow stops until RTS goes high again. Likewise, when the CTS signal from the modem to the DTE goes low, the data flow stops until it goes high. ENQ/ACK - If the modem is being used with Hewlett Packard (HP) (or similar) equipment that employs ENQ/ACK pacing, the modem can be configured to respond to ENQ/ACK commands, making it compatible with HP systems. Doing so does not effect any other flow control or pacing already configured in the modem. When configured for ENQ/ACK, the ENQ (control-E) and ACK (control-F) signals from the HP equipment will be accepted and responded to according to HP protocol. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg028 7.0 RS-232 SUMMARY The DM424 modem is designed to meet the EIA (Electronic Industries Association) RS-232 standards. The modem uses the following RS-232 pin assignments. ____________________________________________________________________ | RS-232 DSI EIA SIGNAL CIRCUIT | | PIN DESIGNATION CIRCUIT SOURCE FUNCTION | |------------------------------------------------------------------| | 2 SD BA DTE Transmit Data | | 3 RD BB DCE Receive Data | | 4 RTS CA DTE Request-To-Send | | 5 CTS CB DCE Clear-To-Send | | 6 DSR CC DCE Data Set Ready | | 7 SG AB - Signal Ground | | 8 DCD CF DCE Data Carrier Detect | | 15 TC DB DEC Transmit Clock | | 17 RC DD DCE Receive Clock | | 20 DTR CD DTE Data Terminal Ready | | 22 RI CE DCE Ring Indicator | | 24 SCTE DA DTE External Clock | |__________________________________________________________________| SD Data is sent to the modem from the terminal device on this pin. RD Data is sent from the modem to the terminal device on this pin. RTS This pin is a signal from the terminal to the modem that the terminal wishes to send data. CTS This signal is from the modem to the terminal that the modem is ready to receive data. CTS can be forced on, set to follow the DCD signal, or set to follow RTS. For most asynchronous hosts it should be set to follow DCD. For dumb terminals it should be forced on. For most synchronous devices it should follow RTS. CTS can also be used for asynchronous flow control. DSR This signal is from the modem to the terminal signaling that the modem is ready to try and connect. It should be forced on for dumb terminals and set to follow DTR for most host computers. SG This is the signal ground of the modem. DCD This signal is from the modem to the terminal and indicates that a connection has been established and that "carrier" is present. It should be set to normal RS-232 for most all computers. Some dumb terminals may require that this signal be forced on all the time. In addition to the AT&C command, Dip Switch 3 can force the signal on. TC This is the transmit clock during synchronous mode that is sent from the modem to the terminal. RC This is the receive clock during synchronous mode that is sent from the modem to the terminal. DTR The Data Terminal Ready signal is an indication from the COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg029 terminal to the modem that the terminal equipment is connected and ready. This signal must be active for the modem to origin- ate or answer a call. Also, during a call, the modem will disconnect if DTR is lost. This signal can be forced on or follow the true DTR status. RI Ring Indicator is a signal from the modem to the terminal indicating an incoming ring. This signal will remain on for the duration of the ring cycle. SCTE This is a clock signal from the terminal to the modem which the modem then uses to generate the transmit clock signal to the terminal. The SCTE signal is only used during sync- hronous operation when the external clock is selected using Dip Switch 4. 8.0 HELPFUL HINTS The following are suggestions for easing the installation, operation and troubleshooting of the DM424 modem. o When a Dip Switch is changed, the modem must be turned OFF and then ON for switch changes to be recognized. o If the modem does not respond to commands from an attached terminal or PC, try forcing DCD high by setting Dip Switch 3 down. If there is still no response, check cabling and the speed of the terminal or PC. The only valid DTE speeds for the DM424 are 1200, 2400, 4800, 9600 and 19,200 bps. o To ensure the DM424 modem is in a known state when first installing the modem, load the factory defaults by entering the command: >AT&F&W from a terminal attached to the DTE port on the modem. Always start by loading factory defaults before customizing the modem for a specific application. o If the modem will not dial out, check to see if the telephone line is plugged into the "TELCO" jack not the "TELSET" jack. Connect a telephone handset to the "TELSET" jack and listen for a dial tone. The modem will not dial out without a dial tone. o For auto-answer only applications, (no origination) set the DM424 modem for Dumb mode (Dip Switch 2 down). This may alleviate a lot of problems when the modem is connected to a host. o If the modem will not answer check the following: 1. Auto-answer must be enabled. Check the value of register S0. Enter: ATS0? NOTE: If the value of S0=0 auto-answer is disabled. Set S0 to the number of rings prior to answering. 2. Observe the TR indicator light for the status of DTR. The modem will not answer unless DTR to the modem is asserted high or DTR is forced high by the command: >AT&D0 NOTE: The default option for DTR is AT&D2. DTR will follow the true state of Pin 20 on its RS-232 connector. COMMUNICATIONS-BASIC FOUR-COMMUNICATIONS------------FIB039 Pg030 CAUTION: On SPx systems, ensure that the 4/8-way or the CMB port used to connect the DM424 modem is jumpered for connection to a modem. All the cabling recommen- dations in this document assumes SPx ports are jumpered for connection to a modem. CAUTION: Do not depend on customer built cables.

Not only is the N.6H OS required, but a new serial cable, PN 916509-B, and a new version of 16way, PN 903437-002, is required too (supported on the 16way only). Below is the pin-out of the 916509 Rev B cable. This cable requires 4-twisted pair cable (existing serial cables are 2-twisted pair, they cannot be converted).

The device will be able to throttle the host, but the host will not throttle the device. (This will correct the 'Data Loss' problem that occurs with ISP printers when they are turned off.) This version of 16way is downwards compatible with earlier OS releases. Flow control is implemented by monitoring the CTS signal of the interface. If CTS drops, the host will cease transmitting until CTS is detected or until specified timeout has occured. If the timeout occurs, a "timeout" error will be returned to the user. The timeout value is reset for each character transmitted. This means that if CTS drops multiple times during a transmission, 5 seconds (for example) will be allowed for each detection of CTS dropping. Hardware flow control is available for any serial device except for SPE.MODEM. Hardware flow control must be configured in TERM. CONFIG for it to be operational. Enter the extended menu (by using 'X' at the prompt ENTRIES CORRECT (Y/N)) for the port being configured and enter Y(es) at the line 'CTS FLOW CONTROL:'. HOW TO OBTAIN 16way -02: The 16way -002 version is NOT required for the use of the N.6H OS release. It is only required for those ports (along with N.6H) that wish to implement hardware flow control. Do NOT replace every 16way in the system. Use the standard procedures in your location that is used for 'Revision Upgrades'. ORIGINATOR: D.

Error 0 results when remote MBF terminals or PCs are performing slave printing. Symptom: When the DM424 is set for factory defaults and used as a host modem, a user dialing in may experience an error 0 in BASIC when performing slave printing using a BFIS interface printer. Cause: The BFIS protocol computes an LRC (Longitudinal Redundancy Check) of characters within a block. When the LRC takes on a hex value of a DC3 (XOFF) the host modem by default will halt forwarding data to the host. This results in a timeout to BASIC which then issues an error 0. Solution: Connect the host end DM424 to a terminal using a "straight through" cable and enter the following commands: >AT&F&W >OK Modem response msg. >ATZ >OK >AT*F1 This enables XON/XOFF (passthrough) >OK >AT&W For an MPx system TERM.CONFIG should be setup as follows: LINE NUMBER : 1 * * Depends on application LINE DEVICE : Terminal LINE TYPE : 4314 * LINE SPEED : 19200 * LINE PARITY : Odd BITS/CHAR : 7 STOP BITS : 1 ================================================================== SLAVE PRINTER : YES PRINTER TYPE : MBF PRINTER LINE LENGTH : 80 * CR ON LF : NO * CHARACTER DELAY : NO DELAY LENGTH : 0 SUPRESS ECHO : NO XON/XOFF : YES MUX DEVICE : NO DELIMITER : I/O TRANSLATE : YES PRINT MESSAGES : YES INPUT TRANSPARENCY : NO OUTPUT TRANSPARENCY : NO RELEASE DETACH : NO * CTS FLOW CONTROL : NO For an SPx system configuration is as follows: 1.

The modems must be capable of MNP class 2 or MNP class 3 reliable link connections (called ARQ Error Correction in the ARK/Paradyne FDX 2400 modems) which sends the characters in error checked packets, utilizes an internal modem buffer and guarantees the validity of the data. This FIB will be updated as more modem configurations are verified. NOTE: 1) Printer throttle in the terminal/PCTERM/PCLINK must be set for XON/XOFF, slave printers configured on SYS 212 are configured as Industry Standard Printers (ISP). 2) If phone lines are a problem, try using "10288" ahead of the dial string. This will switch to AT&T for this call. Frequently their lines are better for modem use. EX. 1028817147303333 3) The phone switch in Tustin may take too long to connect to the first available modem causing your modem to quit too soon. Add pause characters (",") at the end of the dial string to make your modem wait longer for a connect. The pause character can also be used as a delay if you have to dial an outside line first.

NOTE: 1) The QX/12K will only connect to the modems in Tustin at 2400 BPS, the following message should appear when the modem connection is made: CONNECT MNP4 or CONNECT MNP5 The connection is utilizing MNP class 4 error correction protocol, effective throughput should be greater than 2400 BPS. If the CONNECT MNP5 message occurs, MNP class 5 data compression is also being utilized which will greatly increase throughput. 2) The settings listed above were made with the modem idle and not connected. If the modem is connected, the values will change to reflect current conditions. 3) The miscellaneous commands listed for the Microcom SX2400 are the same for the Microcom QX/12K.
