Multi-Com uses Asynchronous Data Link Control (ADLC) communication protocol. ADLC is the heart of Multi-Com and is the single factor that permits concurrent file transfers. Concurrent file transfer is the ability to upload and download files at the same time. Your Multi-Com program has a unique sign on ID and PASSWORD. You must remember your ID and PASSWORD. If lost, it can not be replaced. The ID and PASSWORD are used for automatically logging on to remote PCs that use the Multi-Com FTS host software. You may see other references to the MC-FTS within this manual. The MC-FTS is the "Multi-Com File Transfer System" program. The MC-FTS program is used for unattended host operation with Multi-Com. Multi-Com users can call into the MC-FTS to download and upload files and messages. An operator is not needed to run MC-FTS. The first time Multi-Com is loaded, it should be configured for your particular system. This includes setting the default communication port, baud rate, download path, upload path and system security. To do this, see the configuration section starting on page 3-1. This document file assumes you have a basic understanding of DOS. See your DOS manual if you need more information about DOS and it's commands. Note: The Multi-Com program must be running in both PCs. This program will not transfer files with another system unless that system supports ADLC protocol. Page: 1-1 INTRODUCTION... The program diskette contains the following files: RUN.BAT Batch File To Begin Multi-Com MC105.EXE Multi-Com Program Version 1.05 MC_CNFG.DAT Configuration Data File MC_DIAL.DAT Dialing Directory Data File MC105.DOC This Document File Page: 1-2 HARDWARE REQUIREMENTS Multi-Com will run on an IBM-PC, IBM-XT, IBM-PC Portable, IBM-AT, and IBM Personal System/2 series machines. It will also run on all 100% IBM compatible machines. Downloading or uploading from a diskette drive is supported, but can be slow if only one or two files are being transferred. A fixed disk or VDISK is recommended to increase overall performance. Hardware: - 256k Memory Minimum - 1 Disk Drive Minimum (VDISK or Fixed Disk Recommended) - Color or Monochrome Adapter - Color or Monochrome Display - Asynchronous Communication Adapter and External Modem or - Internal Modem Note: Multi-Com will not operate on a PCjr or on any machine that does not have DMA and COM adapter hardware interrupt support. Page: 1-3 SOFTWARE REQUIREMENTS Multi-Com will run under DOS version 2.1 through 3.3 or TopView 1.0 through 1.1. If running under TopView, the screen must not be defined as mode 3 or 7. All other modes will work fine. You should unload all memory resident programs before starting Multi-Com. Software: - IBM or MS DOS Version 2.1 Through 3.3 - TopView 1.0 or 1.1 (Not Screen Mode 3 or 7) - CONFIG.SYS file Containing The ANSI.SYS Device Driver Page: 1-4 DOS SETUP Multi-Com uses ANSI control codes to control your screen. In order to properly view certain files, you must include the ANSI.SYS device driver in your system configuration. To do this, include the DEVICE=ANSI.SYS line in the DOS CONFIG.SYS file. If you do not use a CONFIG.SYS file, one must be created. See your DOS manual for more help with CONFIG.SYS and the ANSI.SYS device driver. Because Multi-Com can transfer multiple files at the same time, multiple files will be opened at the same time. This can cause problems for DOS if you do not set aside some memory for managing all of the open files. To do this, put a FILES= command in the CONFIG.SYS file. The maximum amount of open files with Multi-Com will be 20. This is in addition to the files DOS will have open. A FILES=32 in the CONFIG.SYS should provide satisfactory operation with most system configurations. The BUFFERS= command should contain the same value as the FILES= command. A VDISK should also be configured if you have more than 256k of RAM. All memory in excess of 256k can be assigned to the VDISK. See your DOS manual for information about installing a VDISK. The need for a VDISK will be greater for systems that do not have a fixed disk. Diskette based systems will benefit more from the VDISK. CONFIG.SYS: - DEVICE=ANSI.SYS - FILES=32 - BUFFERS=32 - DEVICE=VDISK.SYS (see your DOS manual for parameters) Page: 1-5 GETTING STARTED Before you load Multi-Com you must have the following files in your default directory. It may be easier for you to create a sub-directory with the DOS MD command and place the four Multi-Com files in the newly created directory. RUN.BAT Batch File To Start Multi-Com MC105.EXE Program File Version 1.05 MC_CNFG.DAT Configuration Data File MC_DIAL.DAT Dialing Directory Data File The following is an example of the recommended DOS tree structure: (root directory) │ │ (com program sub-directory) (your other sub-directories) │ │ │ │ │ └──────────────────────────┐ │ └──────────────────┐ │ (com program 1) (com program 2) (MC) <--The Multi-Com sub-directory) ││ ┌─────┘└────┐ │ │ (DOWN) (UP) Sub-Directory ------------- MC Contains Base Files: MC105.EXE MC_CNFG.DAT, MC_DIAL.DAT and RUN.BAT MC\DOWN Will Contain Files That You Receive From The Other Machine MC\UP Contains Files That You Will Send To The Other Machine Note: The Multi-Com sub-directory MC can be anywhere on your disk. Page: 2-1 PROGRAM LOAD To begin Multi-Com enter RUN on the DOS command line. RUN is a batch file used to start Multi-Com. RUN will check that needed files are in the default directory. After the program loads, the logo screen will appear on the default monitor. Multi-Com will now wait for you to enter your personal ID and PASSWORD. Your personal ID is used for automatically logging on to remote PCs that use the Multi-Com FTS host software. The following is a portion of the Multi-Com log screen. When you see this screen, enter your ID and PASSWORD. (C) Copyright C.P. Fricano 1984, 1988 Pittsburgh, PA All Rights Reserved ID Word:_ Password: ────────────────────────────────────────────────────────────────────── Version x.xx After the correct ID and PASSWORD are entered, your use license, name and address will replace your ID and password. The MAIN MENU will be shown on line 24 and 25 with the DialingDirectory option highlighted. Page: 2-2 MENU SELECTION All Multi-Com menus have the same format. Line 24 contains the command selections and line 25 contains the alternate key and a help message for that command. Most commands may be selected one of three ways: 1) Enter the first letter of the command. 2) Move the command window with the left and right arrow keys and press the ENTER key (NumLock must be off). 3) Press the alternate key for that command (optionally shown between the brackets on line 25). Note: The Esc key will always select the LAST menu item. The last menu item is always a command that will exit the current menu and return control to the previous menu or screen. Page: 2-3 MAIN MENU TERMINAL Configuration DialingDirectory Exit [ Com:1 Baud:1200 ] Begin Multi-Com terminal program The main Multi-Com menu has four commands from which to choose. The command may be selected by pressing the first letter of the command or by moving to the command with the left/right arrow keys and pressing ENTER. While the MAIN MENU is displayed, the communications line is not enabled. The modem can not send or receive information. Remember: The left and right arrow keys (cursor movement keys) will only work when Numeric Lock is turned off. Page: 2-4 MAIN MENU... TERMINAL COMMAND TERMINAL Configuration DialingDirectory Exit [ Com:1 Baud:1200 ] Begin Multi-Com terminal program The first main menu command is called TERMINAL. TERMINAL will take you directly to the Multi-Com communications screen. Multi-Com will enable the communication line by raising the DTR (Data Terminal Ready) signal to the modem. Multi-Com will then check to make sure the line is enable by looking at the DSR (Data Set Ready) signal from the modem. See page 5-1 for more information about the TERMINAL operation. CONFIGURATION COMMAND Terminal CONFIGURATION DialingDirectory Exit [ Com:1 Baud:1200 ] Display/Alter initial program settings The second command is CONFIGURATION. This command is used to set the default com port, baud rate, upload/download paths and to enable or disable RDOS security. The com port and baud rate set here are used as initial settings when the program is loaded. They are overridden when you make a connection using the DialingDirectory. See page 3-1 for more information about this command. Page: 2-5 MAIN MENU... DIALING DIRECTORY COMMAND Terminal Configuration DIALINGDIRECTORY Exit [ Com:1 Baud:1200 ] Initiate a call The third command is called DIALING DIRECTORY. This command will take you to the Multi-Com auto-dialer. The auto-dialer is used to program "intelligent" or "smart" modems. The directory holds 20 entries. Each entry has its own system Name, Number, ComPort, Echo local/remote switch and DialCommand. When dialing a remote machine with the DialingDirectory, the com port and baud rate are taken from the individual directory entry. This overrides the initial com port and baud rate set with the "Configuration" command. See page 4-1 for more information about this command. EXIT COMMAND Terminal Configuration DialingDirectory EXIT [ Com:1 Baud:1200 ] End this Multi-Com session The last command, EXIT, will end Multi-Com and return control to DOS or TopView. If the communication line is disabled, Multi-Com will terminate immediately. If it is enabled, another menu will come up. This menu will ask if you want to disable the line or leave it enabled when Multi-Com terminates. Leaving it enabled will keep DTR active. Choosing to disable it will make DTR inactive thus causing the modem to hang up. Page: 2-6 CONFIGURATION MENU Terminal CONFIGURATION DialingDirectory Exit [ Com:1 Baud:1200 ] Display/Alter initial program settings BAUD ComPort DownloadPath UploadPath Protocol Secure Return [ Com:1 Baud:1200 ] Select next baud rate The configuration menu is selected from the MAIN menu by pressing the letter "C". It has seven commands. The Baud and ComPort settings are only used if you do NOT use the DialingDirectory to initiate a call. The individual DialingDirectory entries for Baud and ComPort will override these initial settings. Page: 3-1 CONFIGURATION MENU... BAUD COMMAND BAUD ComPort DownloadPath UploadPath Protocol Secure Return [ Com:1 Baud:1200 ] Select next baud rate The BAUD command is used to set the communication port baud rate. To change the baud rate, move the command window using the left or right arrow keys to highlight the word BAUD. Press the ENTER key to select the next baud rate. The baud rate is displayed between the brackets on line 25. Available baud rates are 300, 1200, 2400, 4800 and 9600 baud. An alternate method for selecting the next baud rate is to press the "B" key. COMPORT COMMAND Baud COMPORT DownloadPath UploadPath Protocol Secure Return [ Com:1 Baud:1200 ] Select next com port The COMPORT command is used to set the default communication port. To change the com port, move the command window using the left or right arrow keys to highlight the word COMPORT. Press the ENTER key to select the next com port. The current com port is displayed between the brackets on line 25. Available com ports are 1, 2, 3 and 4. An alternate method to select the next com port is to press the "C" key. Note: When you use the DialingDirectory to initiate a call, Multi-Com will NOT use the the COM PORT or BAUD rate from the Configuration menu, but rather the COM PORT and BAUD rate from the individual DialingDirectory entry. Page: 3-2 CONFIGURATION MENU... PATH COMMANDS Baud ComPort DOWNLOADPATH UploadPath Protocol Secure Return [ Com:1 Baud:1200 ] Set download path for files that you receive Baud ComPort DownloadPath UPLOADPATH Protocol Secure Return [ Com:1 Baud:1200 ] Set upload path for files that you send The next two commands are used to set the UPLOAD and DOWNLOAD paths. The DOWNLOAD path is where new files will be placed and the UPLOAD path will contain files to be sent to the other machine. These two paths should point to fixed disk or VDISK sub-directories. They may also point to diskette drives. The two paths may be the same. Blank paths are allowed. Due to the nature of concurrent downloading, files that you receive will not be contiguous. That is, they will not be made up of consecutive disk sectors. To eliminate this "hashing of files", the DOWNLOAD path should be a "temporary" area on your disk used only for Multi-Com downloads. Then, after the Multi-Com session has ended, move the newly downloaded files to a more permanent area of your disk. The following is a sample tree structure for the download and upload paths: (MC) <--The Multi-Com sub-directory) ┌─────┘└────┐ (DOWN) (UP) Sub-Directory ------------- MC............. Contains base files MC105.EXE , MC_CNFG.DAT, MC_DIAL.DAT and RUN.BAT. MC\DOWN........ Will contain files that you receive from the other machine. Move these files to a different area on your disk after the Multi-Com session has ended. MC\UP.......... Contains files that you will send to the other machine. Page: 3-3 CONFIGURATION MENU... PROTOCOL COMMAND Baud ComPort DownloadPath UploadPath PROTOCOL Secure Return [ Com:1 Baud:1200 ] Select file transfer protocol The PROTOCOL command is used to alter the file transfer protocol. Version 1.05 of Multi-Com only supports ADLC protocol. ADLC is a concurrent asynchronous file transfer protocol. ADLC, as implemented in Multi-Com, will permit FULL DUPLEX transmission of files between two machines over a single phone line, using a full duplex modem such as a HAYES smart modem or compatible. Concurrent downloading and uploading are supported. Multi-Com uses 7 of the 8 ADLC links in single mode only. Link #1, the console link, is a dual mode link. All links will operate in dual mode only when the terminal is in local or remote loop-back mode. Dual mode operation is both transmitting and receiving over 1 of the 8 concurrent links. Single mode operation is either transmitting or receiving over 1 of the 8 concurrent links. All 8 links will run at the same time regardless of the individual link mode. Link # Mode Use ------ ---- --- 1 TR Dual Mode Link Used For Console To Console Communications (Both Transmit And Receive) 2 T or R Single Mode Link Used For Disk To Device Transmissions (Printer or Plotter) 3 T or R Single Mode Link For Disk to Disk Transmissions 4 T or R Single Mode Link For Disk to Disk Transmissions 5 T or R Single Mode Link For Disk to Disk Transmissions 6 T or R Single Mode Link For Disk to Disk Transmissions 7 T or R Single Mode Link For Disk to Disk Transmissions 8 T or R Single Mode Link For Disk to Disk Transmissions T = Transmit R = Receive TR = Dual Mode Transmit/Receive Page: 3-4 CONFIGURATION MENU... SECURE COMMAND Baud ComPort DownloadPath UploadPath Protocol SECURE Return [ Com:1 Baud:1200 ] System RDOS security: Enabled The SECURE command is used to turn off or to turn on your system's RDOS security. When enabled, the remote user will not be able to access your system with the RDOS feature. Leave this option disabled if you want the remote user to be able to use the RDOS command. See page 5-13 for more information about the RDOS command. RETURN COMMAND Baud ComPort DownloadPath UploadPath Protocol Secure RETURN [ Com:1 Baud:1200 ] Return to MAIN The RETURN command will exit the configuration menu, save any changes that were made and return control to the main menu. Page: 3-5 DIALING DIRECTORY MENU Terminal Configuration DIALINGDIRECTORY Exit [ Com:1 Baud:1200 ] Initiate a call DIAL Edit Prefix Init TermChar WaitTime SpaceConvert Return Initiate a call The DialingDirectory menu is selected from the MAIN menu by pressing the letter "D". It has eight commands. The first command is used to begin dialing a remote machine. The second to edit an individual directory entry. The remaining commands are used to program and control your system's modem. Page: 4-1 DIALING DIRECTORY MENU... DIAL COMMAND DIAL Edit Prefix Init TermChar WaitTime SpaceConvert Return Initiate a call The DIAL command is used to begin dialing a remote machine. After the DIAL command is selected, the following screen will be displayed: Name Number Baud CP Eh Dial Command ────────────────────────────── ──────────────────── ──── ── ── ──────────── 1 UCS-1 1,412/276-1269 1200 1 N D 2 UCS-2 Nm:MC TEST Pw:DEMO 1,412/276-3374 1200 1 N D 3 1200 1 N D 4 1200 3 N D 5 1200 1 N D 6 1200 1 N DT 7 1200 1 N D 8 1200 4 N D 9 1200 1 N D A 1200 1 N D B 1200 1 Y D C 1200 1 N D D 1200 1 N D E 1200 1 N D F 1200 1 N D Dial: --> 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K Return UCS-1 To begin dialing, move the command window to desired entry number with the left and right arrow keys and press enter. The system name is shown on line 25 as you move through the entries. Directly pressing the entry number or letter will also begin the dialing process. Note: The sample screen has 15 entries, the real screen has an additional 5 entries, "G" through "K". Page: 4-2 DIALING DIRECTORY MENU... DIAL COMMAND... DIAL will build two command lines and send them to your modem. Your modem does the actual dialing. The commands that are sent to your modem are made up of different Multi-Com parameters. The parameters in the first modem command are all taken from the DialingDirectory menu. They are PREFIX, INIT and TERMCHAR. They are used to reset or initialize your modem. The format is: 3 TERMCHAR's + PREFIX + INIT + TERMCHAR If TERMCHAR was a carriage return (ASCII 13), PREFIX was AT and INIT was Z , then the modem would be sent: cr cr cr ATZ cr The second command sent to the modem is the actual modem dial command. This includes the DIALCOMMAND and NUMBER from the individual directory entry. The format is: 3 TERMCHAR's + PREFIX + DIALCOMMAND + NUMBER + TERMCHAR If TERMCHAR was a carriage return (ASCII 13), PREFIX was AT , DIALCOMMAND was DT and the NUMBER was 276-3374 , then the modem would be sent: cr cr cr ATDT276-3374 cr Page: 4-3 DIALING DIRECTORY MENU... DIAL COMMAND... The DIAL command will take you to the Multi-Com TERMINAL screen as the modem dials the number. Note: The DialingDirectory DIAL command is preconfigured to work with a HAYES smart modem or compatible on a pulse (non touch-tone) line. You need only to change the phone number and system name in the individual directory entry. See page 4-5 for more information. Page: 4-4 DIALING DIRECTORY MENU... EDIT COMMAND Dial EDIT Prefix Init TermChar WaitTime SpaceConvert Return Edit a directory entry The EDIT command is used to alter the information in the individual directory entry. After selecting the EDIT command, a second menu will be displayed. This second menu is the same as the DIAL command second menu and is used to select an entry for editing. Edit: --> 1 2 3 4 5 6 7 8 9 A B C D E F Return UCS-1 To select an entry for editing, move the command window to desired entry number with the left and right arrow keys and press enter. The system name is shown on line 25 as you move through the entries. Directly pressing the entry number or letter will also select an entry for editing. After an entry has been selected the EDIT menu will display. In the following example, entry number one has been selected for editing. The current settings for this entry are display on line 25. The following pages will show each of the edit items and describe the meaning of each item. 1: NAME PhoneNumber Baud ComPort Echo DialCmd Return Name:UCS-1 Phone:1,412/276-1269 Baud:1200 Com:1 Echo:N Page: 4-5 DIALING DIRECTORY MENU... EDIT COMMAND... 1: NAME PhoneNumber Baud ComPort Echo DialCmd Return Name:UCS-1 Phone:1,412/276-1269 Baud:1200 Com:1 Echo:N The NAME field holds the remote system's name. This field must be non-blank before an entry is considered to be valid. Entries with a blank NAME field can not be used to make a call. 1: Name PHONENUMBER Baud ComPort Echo DialCmd Return Name:UCS-1 Phone:1,412/276-1269 Baud:1200 Com:1 Echo:N The PHONENUMBER field holds the remote system's phone number. This field must contain a valid phone number. It may also contain embedded modem commands. DT2763374 contains a modem DT dial command in front of the phone number. It is better to put only the phone number here and put the modem command in the DIALCOMMAND field. 1: Name PhoneNumber BAUD ComPort Echo DialCmd Return Name:UCS-1 Phone:1,412/276-1269 Baud:1200 Com:1 Echo:N The BAUD rate is selected by moving the command window using the left or right arrow keys to highlight the word BAUD. Press the ENTER key to select the next baud rate. The current baud rate is displayed next to the word BAUD on line 25. Available baud rates are 300, 1200, 2400, 4800 and 9600 baud. An alternate method for selecting the next baud rate is to press the "B" key. Page: 4-6 DIALING DIRECTORY MENU... EDIT COMMAND... 1: Name PhoneNumber Baud COMPORT Echo DialCmd Return Name:UCS-1 Phone:1,412/276-1269 Baud:1200 Com:1 Echo:N The COM PORT is selected by moving the command window using the left or right arrow keys to highlight the word ComPort. Press the ENTER key to select the next com port. The current com port is displayed next to the word COM on line 25. Available ports are 1, 2, 3 and 4. An alternate method for selecting the next com port is to press the "C" key. 1: Name PhoneNumber Baud ComPort ECHO DialCmd Return Name:UCS-1 Phone:1,412/276-1269 Baud:1200 Com:1 Echo:N The ECHO option is used to turn local character echo on or off for this entry. When ECHO is set to a Y (yes), the Multi-Com terminal will display each character (or block) on your screen before it is transmitted to the remote machine. When set to a N (no), it is up to the remote machine to echo keyboard characters. This is only the initial setting. The TERMINAL ALT-E key (local echo toggle) will still operate to change the LOCAL ECHO mode. When connecting to another machine running Multi-Com, ECHO should be a Y (Yes). 1: Name PhoneNumber Baud ComPort Echo DIALCMD Return Edit modem dial command: [D] The DIALCMD option is used to set the command that your modem needs to begin auto dialing a number. This command is normally a D or DT but can contain any valid modem commands. If it contains more than the modem dial command, the dial command must be last in the string. For example, E1M0DT is a valid entry. See your modem manual for information about it's dial command. The default is D . That will dial a HAYES or HAYES compatible modem. Page: 4-7 DIALING DIRECTORY MENU... EDIT COMMAND... 1: Name PhoneNumber Baud ComPort Echo DialCmd RETURN Return to DIAL The RETURN option will return control to the DialingDirectory menu. Page: 4-8 DIALING DIRECTORY MENU... PREFIX COMMAND Dial Edit PREFIX Init TermChar WaitTime SpaceConvert Return Modem attention prefix: [AT] The PREFIX command is used to set your modem attention prefix. This is the string that your modem uses as it's wake-up or attention command. The prefix string will always precede commands that are sent to your modem. For HAYES and HAYES compatible modems, use AT as the attention prefix. See your modem manual for information about it's attention prefix. INIT COMMAND Dial Edit Prefix INIT TermChar WaitTime SpaceConvert Return Modem initial reset: [Z] The INIT command is used to set the initial reset or initialization string that is sent to your modem. This command must not include an attention prefix. The attention prefix is set using the PREFIX command. For HAYES and HAYES compatible modems, use Z as the reset command. You could include other valid commands. Example: E1Q0 (modem echo on, quiet off). See your modem manual for more information. Page: 4-9 DIALING DIRECTORY MENU... TERM CHAR COMMAND Dial Edit Prefix Init TERMCHAR WaitTime SpaceConvert Return Modem command terminator character (ASCII value): [13] The TERMCHAR command is used to change the character that your modem uses as it's command terminating character. For most modems it would be an ASCII 13, which is a carriage return. If your modem needs something other than that value, set it with TermChar. The range is 1 to 255. WAIT TIME COMMAND Dial Edit Prefix Init TermChar WAITTIME SpaceConvert Return Modem wait time between characters: [5] The WAIT TIME command is used to control how fast characters are sent to your modem. The default is 5. Lowering this number speeds up commands to your modem. Increasing this number slows down commands to your modem. If the DialingDirectory is not able to auto-dial your modem, increase this number. The range is 1 to 9. The WaitTime is calculated using the following two formulas: Time between commands = 1.1 sec + ( .1 sec * WaitTime ) Time between characters = .006 sec * WaitTime This gives a range of 1.2 to 2.0 seconds between commands and .006 to .054 seconds between characters. Using the default of 5 yields a time of 1.6 seconds between commands and 30 milliseconds between characters. Some HAYES compatible modems will require the full WaitTime value of 9 before they will auto-dial. Page: 4-10 DIALING DIRECTORY MENU... SPACE CONVERT COMMAND Dial Edit Prefix Init TermChar WaitTime SPACECONVERT Return Character converted to a space: [$] The SPACE CONVERT command is used to change the character Multi-Com will convert to a space within a modem command. The default value is the dollar sign ($) character. If the SpaceConvert character is other than a $ , then the $ character becomes a delay value equal to the WaitTime value in .050 second increments. The delay occurs within a modem command. If the SpaceConvert character is a dollar sign [$] then the command string [^n$DI$123-4567] will be converted to [^n DI 123-4567] before it is sent to the modem. If the SpaceConvert character is an exclamation point [!] (or anything but a dollar sign [$]: then the command string [^n$DI!123-4567] will be converted to [^n(.05sec*WaitTime)DI 123-4567] before it is sent to the modem. The need for the $ delay will vary depending on your modem. It will NOT be needed for HAYES and HAYES compatible modems. Some modems which support two command sets may need an extra delay within the modem command. Page: 4-11 DIALING DIRECTORY MENU... RETURN COMMAND Dial Edit Prefix Init TermChar WaitTime SpaceConvert RETURN Return to MAIN The RETURN command will save all changes made while in the DialingDirectory and return control to the main menu. Page: 4-12 TERMINAL OPERATION TERMINAL Configuration DialingDirectory Exit [ Com:1 Baud:1200 ] Begin Multi-Com terminal The Multi-Com terminal screen is selected by entering a "T" from the main menu, or by using the DialingDirectory to initiate a call. There is a difference between the two. When entering a "T" from the main menu, Multi-Com uses the COM PORT and BAUD rate as show on line 25 of the main menu. When using the DialingDirectory, the COM PORT and BAUD rate are taken from the individual dialing directory entry. See page 3-2 and the EDIT section beginning on page 4-5 for more information. Page: 5-1 TERMINAL OPERATION... STATUS LINE The Multi-Com terminal screen is divided into two areas. A solid divider line on line 24 separates the areas. Lines 1 through 23 are used for console to console communications. Line 25 is the operator information area or status line. The following is an example of lines 23 - 25. ─────────────────────────────────────────────────────────────────────────────── < > Character Terminal LE IN CL NL SL (remote msg) 0 1111111111222222222233333333334444444444555555555566666666667777777777 1234567890123456789012345678901234567890123456789012345678901234567890123456789 │││ │ │ │ │ │ │ └Scroll Lock │ ││└Keyboard└System └Mode Indicator │ │ │ └Numeric Lock │ ││ State State │ │ └Caps Lock │ ││ │ └Insert Mode │ │└─Modem Line State └Local Echo Error Counter┘ │ └──COM Card/Transfer State The following pages will describe the meaning of each status indicator.

Press ENTER when done. Busy Multi-Com is in the process internal MC-MC communications. You must wait until it is complete. The ALT-R key (Reset) is active during this time and will reset the BUSY state. Caution should be used when interrupting Multi-Com with the ALT-R key. BUSY will also be displayed when the remote machine is using DOS via the LDOS command. Page: 5-4 TERMINAL OPERATION... STATUS LINE... Mode Indicator Terminal Characters entered are passed on to the modem and the remote computer's screen. CONTROL-ENTER will take you out of TERMINAL MODE and put you into COMMAND MODE. Command Characters entered are interpreted as internal commands. The ESC or CONTROL-ENTER key will take you out of COMMAND mode and back to TERMINAL MODE. Keyboard Indicators LE LOCAL ECHO mode. All characters typed will be echoed to your screen. IN INSERT MODE is active. No overstriking of characters. CL CAPS LOCK is active. No lower case letters. NL NUMERIC LOCK is active. The cursor control keys are disabled and the numeric pad is active. Numeric lock must be off to use Multi-Com line 25 menus. Page: 5-5 TERMINAL OPERATION... STATUS LINE... The terminal STATUS line may be replaced with COMMAND menus. COMMAND menus are used to ease in the selection of internal commands. The following are three examples of lines 24 and 25. Toggle through the three with the ESC key. Multi-Com is in COMMAND MODE while either MENU #1 or MENU #2 is displayed. See section 5-7 for more information about COMMAND and TERMINAL modes. Terminal STATUS information: ────────────────────────────────────────────────────────────────── <-> Character Terminal LE 0 Command MENU #1: Block Ldos Rdos Upload Download Status Hold QUIT Other Exit Exit command mode and return to terminal mode Command MENU #2: Cls ID Echo Loop Drop Sound Return Function not available at this time Page: 5-6 TERMINAL OPERATION... KEYBOARD USE The keyboard has two modes of operation. They are TERMINAL mode and COMMAND mode. While in TERMINAL mode, all characters typed will be sent to the REMOTE PC. In COMMAND mode, the characters you type are interpreted as an internal command. To switch between COMMAND and TERMINAL mode, hold down the CONTROL key and press the ENTER key. CONTROL-ENTER can be used at any time to toggle between COMMAND and TERMINAL mode. The following pages will describe various keys and their meaning. The descriptions apply when Multi-Con is in TERMINAL mode. To display COMMAND menu #1, press the Esc key. Pressing the Esc key a second time will display COMMAND menu #2. Pressing Esc a third time will re-display the STATUS line and place Multi-Com in back TERMINAL mode. Page: 5-7 TERMINAL OPERATION... KEYBOARD USE... Key Description --- ----------- Control-Enter Toggle between TERMINAL and COMMAND mode. Enter If in TERMINAL mode, transmit the current line to the remote machine. If in COMMAND mode, process the internal command. Home Move cursor to column 1 of current line or move up 1 line if in column 1. Control-Home Move cursor to line 1, column 1. End Move Cursor to last character of the current line. Control-End Move Cursor to line 23, column 1. PgUp Set left margin. ENTER key will reset to column 1. All characters to the left of the newly set left hand margin will be ignored. Arrow Keys Positions cursor on screen. Insert Toggle overstrike mode (ENTER key will reset INSERT mode). Delete Erase the character under cursor and reformat the line. Backspace Erase the character to the left of the cursor. Tab Move cursor right 8 positions. Page: 5-8 TERMINAL OPERATION... F10 "MESSAGE PENDING" KEY When the keyboard is in TERMINAL mode, you may communicate with the other machine's operator by typing messages to him or her with your keyboard. When MC-BLOCK mode is turned OFF, this is not a problem because the other person can see each character as you type. When MC-BLOCK mode is ON the other person has no way of knowing when you are typing. As you type, the characters are placed in a holding buffer until you press your ENTER key. After you press ENTER, the line of information is then sent to the other machine. This can be a confusing situation for both involved. The problem can be kept to a minimum by the use of the F10 key. The F10 key will send the message "MESSAGE PENDING" to the other person and the message "PROCEED" to you. This lets the other person know that you are in the process of typing and that they should wait while you type. If you should receive the message "Message Pending" while typing to another person, you should wait until they are finished. Use the F10 key to let the other person know you have started to type them a message. This will eliminate the confusion of not knowing if someone is typing a message, or waiting. Page: 5-9 TERMINAL OPERATION... INTERNAL COMMANDS To pass information to the other machine's operator, your keyboard must be in TERMINAL mode. To pass internal command information to your Multi-Com program, your keyboard must be in COMMAND mode. There are two ways to give internal commands. The first is to place your keyboard in COMMAND mode by pressing CONTROL-ENTER, then type the command and press ENTER. The second is to press the ESC key to bring up the COMMAND menus. The second way is a much easier way to pass commands to Multi-Com. The COMMAND menus are in the same format as all other Multi-Com menus. Selecting a command from the menu is the same as selecting a command from any of the other Multi-Com menus. The following pages will describe various internal commands. The descriptions apply when the Multi-Con COMMAND menus are displayed. To display COMMAND menu #1, press the Esc key. Pressing the Esc key a second time will display COMMAND menu #2. Pressing Esc a third time will re-display the STATUS line and place Multi-Com in back TERMINAL mode. Page: 5-10 TERMINAL OPERATION... COMMAND MENU #1 Command menu #1 is display by pressing the Esc until the following menu is displayed. BLOCK Ldos Rdos Upload Download Status Hold Quit Other Exit [Ctrl-F1] Initialize Multi-Com Block Mode Page: 5-11 TERMINAL OPERATION... BLOCK COMMAND BLOCK Ldos Rdos Upload Download Status Hold Quit Other Exit [Ctrl-F1] Initialize Multi-Com Block Mode The BLOCK command will initialize Multi-Com BLOCK mode operation. Control-F1 is an alternate key for the BLOCK command. MC-BLOCK mode must be initialized before files can be transferred with another machine running Multi-Com. Once MC-BLOCK mode is active, the STATUS line will change: From: ────────────────────────────────────────────────────────────────── <-> Character Terminal LE 0 To: ────────────────────────────────────────────────────────────────── <=> MC-BLOCK Terminal LE 0 It is very important that a BLOCK command be issued at the start of a Multi-Com to Multi-Com communication session. Without the BLOCK command, Multi-Com will be in CHARACTER mode. Character mode will allow you to type messages, but nothing else. MC-BLOCK mode is required before you can transfer files. The BLOCK command enables the ADLC protocol which is the FULL DUPLEX protocol used for concurrent downloading and uploading. During MC-BLOCK mode initialization, the two machines exchange configuration information which is needed to support concurrent operation. Line errors or noise during the initialization process can cause it to fail. The message "REMOTE STATION HAS FAILED TO RESPOND" indicates that the other machine is not running an ADLC supported program, or line noise was too great to be overcome. If MC-BLOCK mode fails to be set, retry the command. Page: 5-12 TERMINAL OPERATION... LDOS COMMAND Block LDOS Rdos Upload Download Status Hold Quit Other Exit LOCAL DOS, Type EXIT to return to Multi-Com The LDOS command will put the Multi-Com program on hold and load a copy of the COMMAND.COM DOS command processor. To exit LOCAL DOS and return to Multi-Com type the DOS EXIT command. You must have 256k of memory (as stated on page 1-3 ) for this command to work. If files are being transfer, they will be temporarily halted before dropping to DOS. The remote machine's terminal will go "BUSY" while you are using DOS. The remote operator will not be able to access Multi-Com while you are in LDOS. Care should be taken to return to the proper directory before typing EXIT. Do not alter the screen mode while in DOS. Do not move active files in or out of your UPLOAD or DOWNLOAD directory if links were running before the LDOS command was given. Do not load other communication programs while in LDOS. Do not load BASIC or BASICA. BASIC will alter the communication port status and not permit Multi-Com to resume halted file transfers. RDOS COMMAND Block Ldos RDOS Upload Download Status Hold Quit Other Exit REMOTE DOS, Type EXIT to return to Multi-Com The RDOS command is similar to the LDOS command. RDOS will give you access to the remote machine's DOS through Multi-Com's CHARACTER TERMINAL mode. Therefore, this command will be disabled while there are files being transferred. The remote machine must have RDOS SECURITY disabled before you will gain access DOS. Do not alter the standard input/standard output devices while using RDOS. The remote machines STDIN and STDOUT are redirected to the configured com port during RDOS operation. Do not load BASIC or BASICA or any other program that may alter the communication port or standard input/output device. Your best bet is to only use DOS commands (DIR, CHKDSK, COPY, CD, MD, etc...) and then type EXIT to get back out. After exiting RDOS you must issue the BLOCK command to get Multi-Com from CHARACTER to MC-BLOCK mode. See page 5-12 for information about the BLOCK command. Page: 5-13 TERMINAL OPERATION... UPLOAD COMMAND Block Ldos Rdos UPLOAD Download Status Hold Quit Other Exit Copy a file FROM THIS machine TO THE REMOTE machine This is the command that will begin the process of sending a file from your machine to the remote machine. When this command is first selected all active file transfers will be temporarily halted. You will then be prompted to enter the LOCAL INPUT file name. The prompt for the LOCAL INPUT file will include the configured upload path (see page 3-3 for information about path configuration). Enter the name and extension of the file. Do not include a path name. Next, you will be prompted for the REMOTE OUTPUT file name. This field will have as its default the name of the INPUT file. You may change this name or press enter to accept the default. Multi-Com will begin the file transfer using the lowest available link address. Messages will display stating the success or failure of the upload. See page 6-1 for message meanings. Page: 5-14 TERMINAL OPERATION... DOWNLOAD COMMAND Block Ldos Rdos Upload DOWNLOAD Status Hold Quit Other Exit Copy a file FROM THE REMOTE machine TO THIS machine This is the command that will begin the process of getting a file from the remote machine to your machine. When this command is first selected all active file transfers will be temporarily halted. You will then be prompted to enter the REMOTE INPUT file name. Enter the name and extension of the file. Do not include a path name. Next, you will be prompted for the LOCAL OUTPUT file name. The prompt for the LOCAL OUTPUT file will include the configured download path (see page 3-3 for information about path configuration). This field will have as its default the name of the INPUT file. You may change this name or press enter to accept the default. Multi-Com will begin the file transfer using the lowest available link address. Messages will display stating the success or failure of the upload. See page 6-1 for message meanings. Page: 5-15 TERMINAL OPERATION... STATUS COMMAND Block Ldos Rdos Upload Download STATUS Hold Quit Other Exit [ALT-S] Display link status The STATUS command will display a screen showing all active links, their remaining byte count and estimated remaining run time. The ALT-S key is the alternate key for this command. The following is an example of the STATUS screen: Com:1 Baud:1200 Carrier:Up Block:On Link Status Bytes Waiting Time File name 1 TR 0 0 0.0 Console 3 R 1024 1024 .3 FILE1.ARC <-Receive File 4 T 2048 2048 .6 FILE2.DOC <-Send File │ │ │ │ │ │ └──Link │ │ └───Estimated Transfer Time │ Mode │ └───────────Bytes Not Yet Transferred └Link └──Bytes Already Transferred Address Transmit error summary Temporary: 0 <---Errors That Were Recoverable Permanent: 0 <---Errors That Were Not Recoverable (bad news) Correctable: 0 <---Errors That Were Corrected On The First Try Note: High temporary / correctable errors indicate a poor phone connection. ────────────────────────────────────────────────────────────────────── <=> MC-Block Terminal LE 0 Page: 5-16 TERMINAL OPERATION... HOLD COMMAND Block Ldos Rdos Upload Download Status HOLD Quit Other Exit End this Multi-Com session and DO NOT disconnect line The HOLD command is used to end the current Multi-Com session and return to the MAIN menu. THE PHONE CONNECTION IS NOT ENDED. Multi-Com uses the RS-232 DTR line to hang-up the phone. DTR remains active and the modem does not hang-up. This command is disabled if files are being transferred. It is useful if you want to back out of TERMINAL operation and go to the MAIN menu for some reason. If you should come back to the TERMINAL, you must issue the BLOCK command to re-establish MC-BLOCK mode. See page 5-12 for information about the BLOCK command. QUIT COMMAND Block Ldos Rdos Upload Download Status Hold QUIT Other Exit End this Multi-Com session and disconnect phone line The QUIT command is used to end the current Multi-Com session and return to the MAIN menu. The phone connection is ended. Multi-Com uses the RS-232 DTR line to hang-up the phone. DTR is dropped and the modem hangs up. This command is disabled if files are being transferred. Once issued, you must re-dial the remote machine to make a connection. Page: 5-17 TERMINAL OPERATION... OTHER COMMAND Block Ldos Rdos Upload Download Status Hold Quit OTHER Exit Manual command entry The OTHER command will let you manually type in one INTERNAL command and then automatically switch from COMMAND mode to TERMINAL mode. This is useful if you must enter a command that is not available from either of the two COMMAND menus. For example, to force sound on you can press ESC O and then type SOUND ON and press ENTER. When completed, you will be back in TERMINAL mode. EXIT COMMAND Block Ldos Rdos Upload Download Status Hold Quit Other EXIT Exit command mode and return to terminal mode The EXIT command will end menu #1 and return to TERMINAL mode. Other keys active while menu #1 is displayed are: CONTROL-ENTER Exit COMMAND mode and return to TERMINAL mode Esc Display COMMAND menu #2 Page: 5-18 TERMINAL OPERATION... COMMAND MENU #2 Command menu #2 is display by pressing the Esc until the following menu is displayed. CLS ID ECHO Loop Drop Sound Return [ALT-C] Clear the screen CLS COMMAND The CLS command clears the screen and places the cursor on line 23, column 1. The ALT-C key is the alternate key for this command. ID COMMAND The ID command is used to request the remote machine's user ID number and program version. Each copy of Multi-Com has a unique user ID number. ID number 9999 is a special ID used for demo versions only. ECHO COMMAND The ECHO command will toggle the keyboard echo state. The ALT-E key is the alternate key for this command. If echo is on, it will be turned off. If echo is off, it will be turned on. The echo indicator is on line 25, column 47. Page: 5-19 TERMINAL OPERATION... LOOP COMMAND Cls Id Echo LOOP Drop Sound Return Place UART in test loop mode The LOOP command will place the communication port in local wrap mode. Local wrap mode is useful for becoming familiar with Multi-Com in a stand alone environment. While in loop mode, Multi-Com will think there is another machine connected to the modem and all functions will be active. The letter L will replace the < on line 25 to indicate that loop mode is active. All file transfer links will operate in dual mode while loop mode is active (see page 3-4 for information about dual mode). Note: The LOOP command will not function on a PC-AT serial/parallel card. DROP COMMAND Cls Id Echo Loop DROP Sound Return Stop an active link -- A partial file will exist on the R.LINK's machine To halt a file transfer that is already in progress, you must use the DROP command. DROP will prematurely end a TRANSMIT or RECEIVE link. The machine that was receiving the file will then have an incomplete file on its disk. DROP must be manually entered. The format for the DROP command is: DROP xx Where xx is the link address to be dropped. Put your keyboard in COMMAND mode by pressing CONTROL-ENTER from the terminal screen. Use the STATUS command (page 5-16 ) to display active links and their addresses. Page: 5-20 TERMINAL OPERATION... SOUND COMMAND Cls Id Echo Loop Drop SOUND Return [ALT-T] Toggle T/R sound on The SOUND command will turn block sound on if it is off or off if it is on. Block sound is a short "tic" from the speaker each time a block of information is received from or sent to the remote machine. RETURN COMMAND Cls Id Echo Loop Drop Sound RETURN Return to terminal mode The RETURN command will turn off menu #2 and return to the TERMINAL mode of Multi-Com. The TERMINAL status line will be displayed on line 25. Page: 5-21 TERMINAL MESSAGES MESSAGES The following pages will contain messages that you may see during Multi-Com TERMINAL operation. Some messages will contain the words LOCAL, REMOTE, INPUT and OUTPUT. The reference to LOCAL will refer to your machine. Likewise, REMOTE refers to the other machine. INPUT is a source file either on the local or remote machine and OUTPUT is the destination file either on the local or remote machine. Multi-Com TERMINAL messages will be displayed between two brackets []. Most messages originate from the local machine, but it is possible for the remote machine to send informational messages to your screen. Page: 6-1 TERMINAL MESSAGES... MESSAGES... [ All MC Links Are In Use ] The DOWNLOAD or UPLOAD request can not be completed because there are no links available for the transfer. This is because all links are currently in use or the MC-FTS reduced the number of available links. Multi-Com has a maximum of eight transfer links. Link #1 is always used for console-to-console communications. Link #2 is only used when a file is transferred from disk to a printer. Link #3 to link #8 are used for disk-to-disk transfers. If you had 6 disk-to-disk file transfers running and tried to start the seventh, this message would be posted because the seventh disk-to-disk transfer can not use link #2. [ BLOCK MODE Is Active ] The BLOCK command has successfully enabled Multi-Com BLOCK MODE. The terminal has switched from CHARACTER TERMINAL mode to MC-BLOCK mode and the ADLC protocol is now in control of the communication line. Users with external modems will see the two machines exchanging ADLC READY commands in the modem lights. [ Carrier Detect ] Carrier has been detected by the modem. The status line will change from < > to <-> to indicate that carrier is up. Page: 6-2 TERMINAL MESSAGES... MESSAGES... [ Copy Aborted ] The UPLOAD or DOWNLOAD request was not completed due to an error in the INPUT or OUTPUT file. [ Copy In Progress ] The UPLOAD or DOWNLOAD request has started. This message is posted before the first data block of the file is transferred. A second message could follow this message indicating a failure. [ DOS Access Attempt Denied ] The REMOTE machine issued the RDOS command to gain access to your machine's DOS and RDOS security is enabled. The REMOTE machine can not access your DOS while RDOS security is enabled. [ Drop Request Sent To Other Station ] Multi-Com is requesting a RECEIVE link to be dropped. Since it is a receive link, the other machine must issue the DROP command. This message will be followed by another message indicating the remaining byte count. Page: 6-3 TERMINAL MESSAGES... MESSAGES... [ Dropping T Link: xx yy Bytes NOT Transferred ] The file transfer has ended on transmit link xx. There are yy bytes that have NOT been transferred. If the yy number is anything other than zero an incomplete file has been created and data was lost. The reason for ending the transfer before all bytes were transferred is because of one of the following: 1) The DROP command was issued by either the LOCAL or REMOTE operator. 2) More than 5 consecutive temporary errors occurred. 3) LOCAL/REMOTE disk read or write error. [ End of List ] Displayed at the end of any DIR request. [ Error In REMOTE OUTPUT File [ xx ] ] A REMOTE file output error has occurred. This can be caused by copying to a printer that is turned off. Check the file name, ext, drive, or device name. The file transfer is ended. [ Error In LOCAL OUTPUT File [ xx ] ] A file open error has occurred. This can be caused by copying to a printer that is turned off. Check the file name, ext, drive, or device name. The file transfer is ended. Page: 6-4 TERMINAL MESSAGES... MESSAGES... [ Error Opening File [ xx ] ] A LOCAL or REMOTE file open error has occurred. This can be caused by copying to a printer that is turned off. The file transfer is ended. [ Error Opening LOCAL OUTPUT File [ xx ] ] A file open error has occurred. This can be caused by copying to a printer that is turned off. Check the file name, ext, drive, or device name. The file transfer is ended. [ Error Opening LOCAL INPUT File [ xx ] ] A file open error has occurred. This can be caused by copying to a printer that is turned off. Check the file name, ext, drive, or device name. The file transfer is ended. [ File Not Found: [ xx ] ] File xx is not found on the specified drive. The file transfer is ended. [ Function Disabled ] You issued a command that can not be completed. For example, the BLOCK command can only be given if carrier is up. The QUIT command will only work if no files are being transferred. Page: 6-5 TERMINAL MESSAGES... MESSAGES... [ INPUT Can Not Be a Device ] The DOWNLOAD or UPLOAD input name can never be a device name. The file transfer is ended. [ LOCAL INPUT File [ xx ] Has Been Opened ] The DOWNLOAD or UPLOAD request has opened an INPUT file on your machine. The xx field is the file name. If xx is on a diskette, do not remove the diskette. [ LOCAL OUTPUT File [ xx ] Has Been Opened ] The DOWNLOAD or UPLOAD request has opened an OUTPUT file on your machine. The xx field is the file name. If xx is on a diskette, do not remove the diskette. [ LOCAL OUTPUT File [ xx ] Will Be Overwritten...<C>ontinue <A>bort ] The LOCAL OUTPUT file xx has been found to exist. This means that there is already a file by the name xx on you disk. You must decide whether to cancel this file transfer or to continue. If you continue, file xx that already exists will be replaced by the new file from the other machine. It is a good practice to never overwrite a file. Page: 6-6 TERMINAL MESSAGES... MESSAGES... [ LOCAL Read Error ] An I/O error occurred while reading from your disk. This causes the link to be dropped. Check your CONFIG.SYS file for a FILES=32 command. [ LOCAL Write Attempted To Inactive Link ] The REMOTE machine has sent a data block to your machine and the link address in the block was found to be inactive. This message can occur if a DROP command was issued by you and the remote machine continued to send information using the dropped link address. This message may be displayed two or three times before the other machine has a chance to process the DROP command. Constant messages of this type indicates a problem with the REMOTE machine. You should consider ending the communication connection by using the QUIT FORCE command. [ LOCAL Write Error ] An I/O error occurred while writing to your disk. This causes the link to be dropped. Make sure you have enough of free space on your disk. Also, check your CONFIG.SYS file for a FILES=32 command. [ Message Pending ] The other operator has pressed the F10 key. This means they are in the process of typing a message to you. You should wait for them to complete. Page: 6-7 TERMINAL MESSAGES... MESSAGES... [ No Carrier ] The modem has sensed that carrier has been lost. The status line will change from <-> or <=> to < > to indicate that carrier is no longer present. [ OUTPUT Can Not Be a Device ] The DOWNLOAD or UPLOAD output name must be a file name and not a device name. This message will be posted if link #2 is in use and you try to use link #3 - #8 for disk-to-device transfers. [ OUTPUT Device Is Invalid ] The output device name in a download or upload request can not be used for output. LPT1:, LPT2:, SCRN:, are examples of valid device names. CAS1:, COM1:, KYBD: are examples of invalid device names. [ Permanent Error On Link: xx ] Five consecutive transmit errors occurred on link xx. That link will now be dropped and made unavailable for the remainder of this session. Page: 6-8 TERMINAL MESSAGES... MESSAGES... [ Poor Connection ] This message is display if carrier is temporarly lost. This can mean a bad phone line connection exists. No information is lost. [ Press Esc For Terminal Menu ] This message is always display after BLOCK MODE is turned off. It is just a reminder message that the ESC key will display the TERMINAL MENU. [ Proceed: ] You have pressed the F10 key. F10 will send the "MESSAGE PENDING" message to the other machine and display "PROCEED" on your machine. Multi-Com is ready for you to begin typing your message. [ REMOTE OUTPUT File: [ xx ] Will Be Overwritten...<C>ontinue <A>bort ] The REMOTE OUTPUT file xx has been found to exist. This means that there is already a file by the name xx on the other machine's disk. You must decide whether to cancel this file transfer or to continue. If you continue, file xx that already exists will be replaced by the new file from the other machine. It is a good practice to never overwrite a file. Page: 6-9 TERMINAL MESSAGES... MESSAGES... [ REMOTE Read Error ] A read error occurred on the REMOTE machine. Multi-Com will now issue the DROP command to end the file transfer. [ REMOTE Station Has Failed To Respond ] This message indicates that the REMOTE machine is not responding to internal Multi-Com requests. The REMOTE machine may not be an ADLC compatible machine or phone line noise may be to great. [ REMOTE Write Error ] A write error occurred on the REMOTE machine. Multi-Com will now issue the DROP command to end the file transfer. [ Reset Error ] An error occurred during the ADLC machine to machine reset procedure. [ Resetting BLOCK MODE ] Multi-Com has turned off MC-BLOCK mode. This message is the first message displayed when the terminal is started. It is also displayed at the beginning of the BLOCK command. It is always followed by the reminder message [ Press Esc for terminal menu ]. Page: 6-10 TERMINAL MESSAGES... MESSAGES... [ Requested Link Has Been Disabled ] The DOWNLOAD or UPLOAD command can not complete because the link you are trying to use has been disabled. [ Requested Link Is In Use ] You are trying to use a link that is already in use. For example, trying to transfer more than six files or trying to use more than one device (LPT1: and SCRN:). [ Remote Not Compatible ] The REMOTE version of Multi-Com is not compatible with your version. Use the ALT-I key to request the other machine's Multi-Com version. [ Sending BLOCK MODE Request ] Your machine has sent a request to the other machine to enable it's MC-BLOCK mode. [ Setting BLOCK MODE ] The BLOCK command has been given and Multi-Com is in the process of enabling MC-BLOCK mode. This message will be follow by [ BLOCK MODE is Active ] if the BLOCK command was successful. Page: 6-11 TERMINAL MESSAGES... MESSAGES... [ Source/Destination Conflict ] When using the manual COPY command, one file must be LOCAL, that is, no equal sign (=) in front of file name. The other must be REMOTE, an (=) must be used in front of the file name. [ Syntax Error ] You entered a valid command but the command parameters are incorrect. Check the command parameters and retry. [ Temporary Error On Link: xx ] An error occurred on link xx but was retried and the retry operation was successful. No information was lost. This message is not displayed if a retry operation failed. Five consecutive temporary errors is considered to be a permanent error and that link will be dropped. Use the ALT-S key to view transmit error statistics. Line quality can be determined by dividing the TEMPORARY errors by the CORRECTABLE. A value less than 3 is considered to be a good connection, 3 or 4 is a fair connection. More than 5 is a poor connection and you should consider ending the communication link and re-dial. Page: 6-12 TERMINAL MESSAGES... MESSAGES... [ Transmitter Not Ready, Timeout: xx ] This message indicates a problem with the ADLC transmitter. The ADLC transmitter in your machine indicated it was ready to transmit, but the other machine is not releasing the transmitter. If you were typing a message to the other machine's operator, resend the last message. Time out values higher than 1 indicate a serious problem and you should consider ending the communication connection by using the QUIT FORCE command. [ Unable To Load DOS ] The LDOS command was given but when Multi-Com tried to load COMMAND.COM an error occurred. Make sure that COMMAND.COM is available and that you have enough memory on your system. [ Unknown Command ] You have entered and invalid or misspelled command. [ Xmitter Not Ready (40) ] A fatal ADLC communication error has occurred. Information has been lost. You should end the communication connection as soon as possible. If links were running, do a ALT-S and write down the active receive file names. Delete these files. They contain incomplete information. Page: 6-13 TERMINAL MESSAGES... MESSAGES... [ Xmitt String Too Long/Short (20) ] A fatal ADLC communication error has occurred. Information has been lost. You should end the communication connection as soon as possible. If links were running, do a ALT-S and write down the active receive file names. Delete these files. They contain incomplete information. [ Xmitter Return Code Unknown: xx ] A fatal ADLC communication error has occurred. Information has been lost. You should end the communication connection as soon as possible. If links were running, do a ALT-S and write down the active receive file names. Delete these files. They contain incomplete information. Page: 6-14 CLOSING CLOSING Multi-Com is not a standard communication program. Do not become discouraged during your learning period. The idea of transmitting a file from one machine to another over phone lines can be difficult to understand. Understanding concurrent file transfers and multiple file links and command mode and terminal mode and LDOS and RDOS and well, you get the idea....please be patient and Multi-Com will become a welcome addition to the communication software that you are presently using.
