Your PC must have at least 96k of memory and one disk. FDC works best at or above 1200 baud. 300 baud links are supported but console response time is increased. It is not recommended to run FDC at speeds slower than 300 baud. FDC uses Asynchronous Data Link Control ( ADLC ) protocol. ADLC is described in document file ADLC102.DOC. FDC can maintain and control 4 communication links between the 2 PC's. All 4 links run concurrently. FDC is a User Supported program. I am requesting a donation of $20.00 for its use. Those that contribute to FDC's support will receive announcements of future updates. FDC may be copied and shared with other private IBM-PC owners, as long as there is no charge for the copy. Multiple copies of FDC may not be used by corporations or other places of business.

FDC Page 06 STARTING FDC To start FDC , at the DOS prompt , type FDC and press return. The logo screen will print on the default monitor. FDC will now print: Enter COM Port (1,2) [1]: _ Enter the communications port that your modem is connected. If your modem is on port 1 ( COM1: ) , you can just press the return key. Next you will see : Enter Baud Rate (300,1200,2400) [1200]: _ You can enter any baud rate from 75 to 9600 here. The default is 1200 baud. It is not recommended to run FDC at speeds slower than 300 baud. Next you must tell FDC what type of monitor to use: Enter Monitor Type (MONO,COLOR) [MONO]: _ The monochrome adapter is the default. Some IBM-PC look alikes use a monochrome display with a graphics adapter card. In this case , you must enter COLOR even though the display is black and white. FDC Page 07 AUTOMATIC RESPONSE FILE All of the above responses may be placed in file FDC.ARF to permit automatic loading. The sequence is: com port baud rate monitor Example FDC.ARF automatic response file: 1 1200 COLOR This will set FDC to 1200 baud on port 1 using the color adapter card. To create the ARF file , use the DOS copy command ( A>copy con: fdc.arf ) and enter the three line followed by a CONTROL-Z (^Z) , and the ENTER key. FDC Page 08 USING FDC After FDC is loaded , you will notice a solid divider on line 24. This line separates the OPERATOR INFORMATION AREA ( OIA ) from the rest of the screen. Here is an example of the OIA as seen when FDC is first loaded. ─────────────────────────────────────────────────────────────────────────────── Ready Terminal Mode LE IN CL NL SL 0 11111111112222222222333333333344444444445555555555666666666677777777778 12345678901234567890123456789012345678901234567890123456789012345678901234567890 │││ │ │ │ │ │ │ └Scroll Lock │ ││└Keyboard└System └Mode Indicator/ │ │ │ └Numeric Lock │ ││ State State Message Area │ │ └Caps Lock │ ││ │ └Insert Mode │ │└─Modem Line └Local Echo Error Counter┘ │ State │ └──COM Card State FDC Page 09 USING FDC... COM Card State The communication card is able to send information to the modem and the REMOTE PC. L The communication card is in diagnostic wrap mode and not able to communicate outside the PC. Modem Line State (blank) Carrier is not present at the modem. FDC can not send or receive information. - Carrier is present at the modem. The LOCAL system is in NON-FDC state. Normal DUMB terminal operation. Carrier is present at the modem. An FDC link has been established between the two PC's. Keyboard State The keyboard is ready to accept characters for processing and/or transmission. ▒ The keyboard is able to accept characters for processing , but is unable to transmit to the other PC. █ The keyboard is locked. No characters can be entered. FDC Page 10 USING FDC... System State Ready Normal dumb terminal operation. As each character is typed , it is sent out of the COM port to the modem. FDC-Ready Full duplex operation. As each character is typed , it is placed in a holding buffer for processing after the ENTER key is pressed. Mode Indicator Terminal When the ENTER key is pressed , the line is not interpreted as an internal FDC COMMAND. Characters are passed to the modem and onto the other computer. Command When the ENTER key is pressed , the line is interpreted as an internal FDC COMMAND. Characters are not passed to the other computer. Keyboard Indicators LE 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. Error Counter (count) Total retry attempts while in FDC mode. FDC Page 11 USING FDC... Here is an example of lines 21 through 25 while in FDC mode , before the ENTER key is pressed: This is a test of FDC_ ─────────────────────────────────────────────────────────────────────────────── FDC-Ready Terminal Mode LE IN CL NL SL 0 After the ENTER key is pressed: This is a test of FDC _ ─────────────────────────────────────────────────────────────────────────────── ▒ FDC-Ready Terminal Mode LE IN CL NL SL 0 After the REMOTE PC has acknowledged the message: This is a test of FDC _ ─────────────────────────────────────────────────────────────────────────────── FDC-Ready Terminal Mode LE IN CL NL SL 0 FDC Page 12 KEYBOARD The keyboard has two modes of operation. They are TERMINAL mode and COMMAND mode. While in TERMINAL mode , any characters you type will be sent to the REMOTE PC. In COMMAND mode however, the characters you type are sent to FDC and are interpreted as an internal command. To switch between COMMAND and TERMINAL modes, hold down the CTRL key and press the ENTER key. This is what I will refer to as a CONTROL-ENTER. CONTROL-ENTER can be used at any time to toggle between COMMAND and TERMINAL mode. CONTROL-ENTER Toggle between TERMINAL and COMMAND mode ENTER Send line to other PC or process command if in COMMAND mode HOME Move cursor to position one of current line CONTROL-HOME Move cursor to line one , position 1 END Move Cursor to last character position of current line CONTROL-END Move Cursor to line 23 , position 1 PgUp Set left margin. ENTER key will reset to column one Arrow Keys Positions cursor on screen Insert Toggle overstrike mode Delete Erase character and reformat line BACKSPACE Erase character TAB Move right 8 positions FDC Page 13 COMMANDS FDC supports the following commands. To enter a command , put FDC in COMMAND mode by using CONTROL-ENTER. Then type the command followed by the ENTER key. The brackets [] indicate optional information that may not have to be entered. CLS clear screen COPY [/][d:]source.ext [[/][d:]dest.ext] DATE [mm-dd-[yy]yy] DIAL modem command DIR [/][d:][filename.ext] DROP link# ECHO toggle Local Echo ID request version from other station LOOP toggle COM card wrap mode QUIT return to DOS RESTART STAT display FDC link status TIME [hh:mm[:ss]] FDC Page 14 COMMANDS... CLS ALT-C Clears the screen. COPY [/][d:]source.ext [[/][d:]dest.ext] The COPY command is similar to the PC-DOS COPY command. Notice the addition of the slash (/). This character is used to indicate a file name on the REMOTE system. For example: [ COPY A:FDC.EXE /B:FDC.EXE ] will copy FDC.EXE from your drive a: , to the REMOTE system's drive B:. Here are a few examples of the COPY command and what they will do. COPY /A:FDC.DOC copy file from REMOTE drive A: to your drive A: COPY C:FDC.ARF copy file from your dive C: to the REMOTE drive C: COPY A:ABC.1 /A:DEF.2 copy file ABC from your drive A: to REMOTE file DEF.2 COPY A:DMS /LPT1: copy file from your drive A: to the REMOTE printer COPY /A:FDC.DOC LPT1: copy file from REMOTE drive A: to your printer COPY /C:DOC NUL.111 copy file from REMOTE drive C: to a NUL file (TEST ONLY) Invalid Devices: KYBD: CAS1: CAS2: COM1: COM2: AUX: CON: Valid Devices: LPT1: LPT2: SCRN: NUL.xxx FDC Page 15 COMMANDS... DATE [mm-dd-[yy]yy] ALT-D The DATE command with no parameters will display the current date. DATE with mm-dd-yy parameter will set the date. DIAL modem command Sends a command to a smart modem. For example: DIAL ATD412- 276-1269 will tell a Hayes modem to dial 412-276-1269 DIR [/][d:][filename.ext] List file names from disk. Notice the slash again. It is again used to indicate the REMOTE system. For example: DIR /B:*.COM will list all files with the .COM extension from the REMOTE PC. DIR C: will list all files from your drive C: DROP link# The DROP command is used to prematurely end a file transfer. Use the STAT (ALT-S) command to see the link number for the file you want to abort. [ DROP 2 ] will stop a file exchange on link #2. FDC Page 16 COMMANDS... ECHO ALT-E Toggle local echo. The only time you would want to use this command is when testing via the ATS16=1C1D Hayes command or LOOP (ALT-L) wrap command. ID ALT-I Request version from other station LOOP ALT-L This command will toggle the IBM COM1: or COM2: card's ability to do a diagnostic wrap. Using ALT-L , followed by CTR-F1 , will run FDC as if it were connected to another PC. All data is wrapped back into the PC for hardware verification. QUIT Exit FDC and Return to DOS RESTART CONTROL-BREAK Restart FDC FDC Page 17 COMMANDS... STAT ALT-S Print statistics on all links. Example: T.Link Status Time Bytes Sent Waiting EST Name 1 ACTIVE 40.0 124 0 0.0 Console 2 INACTIVE 40.0 0 0 0.0 3 ACTIVE 10.0 60,128 5,024 1.0 TESTFILE.XXX 4 INACTIVE 20.0 0 0 0.0 R.Link Status Time Bytes Received Name 1 ACTIVE 40.0 381 Console 2 INACTIVE 40.0 3 INACTIVE 10.0 4 ACTIVE 5.0 30,265 SAMPLE.UCS The above report means you are sending file TESTFILE.XXX to the other PC using link #3. That link has been running for 10 minutes and has sent 60,128 bytes with 5,024 bytes left to go. Estimated remaining transfer time is 1 minute. You are receiving file SAMPLE.UCS from the other PC on link #4. Link #4 has been running for 5 minutes. Link #2 has been inactive for 40 minutes. Link #1 has been active for 40 minutes. FDC Page 18 COMMANDS... TIME [hh:mm[:ss]] ALT-T The TIME command with no parameters will display the current time. TIME with hh:mm:ss parameter will set the time. FDC Page 19 FUNCTION KEYS F1 Display the help menu. F10 Send "Message Pending" message to other station When in FDC mode , the other PC user will not know if you are entering a message. Use F10 key to let him/her know you are building a message to send. Control-F1 This key is used to initialize an FDC session between the two PC's. After pressing Control-F1 , the program will switch to FDC mode if not already there , and attempt to communicate to the other machine using ADLC protocol. If no response is received , one retry will be attempted. If still no response is received, FDC mode will be turned off. If the other machine is capable of FDC mode , the message "Remote Station On-line" will be displayed. You can now begin console communication file and file transfers. FDC Page 20 MESSAGES All Links Are In Use COPY request can not be completed because no links are available for the transfer.
