R T T Y 2 2 0 0 . 0 0 for IBM-PC MSDOS SYSTEMS BY Perry Taylor, W0SE JAN 1st., 1986 The RTTY 2000 series of Amateur Radio Teletype Programs were originally developed for Heathkit Computers, and are based on much of the original work of Irv Hoff, W6FFC, Keith Peterson, W8SDZ, and others, on the Heath Computer net. This series of programs has added split screen, and consolidated some of the concepts and programs, originated by the group on the net. One of features of the program, that may be new to many who first use this program, is the 3rd and 4th level transmit and receive of ASCII characters, via the BAUDOT level code. By adding a third and fourth level shift, to the two already available in the BAUDOT code, it is possible to send all the ASCII characters, over the BAUDOT channel. This is done by making a third shift of BLANK-FIGS, and a fourth of BLANK- LTRS. The use of this feature is explained in the body of this file. Prior to using this version of RTY.EXE, please remove or erase any previous RTY.CFG file. Set TIME/DATE for MS-DOS, as this is used in the RTY program. Use all "UPPER-CASE" while configuring the RTY program. This version of RTY requires 192k or more of RAM, and version 2.0 or higher of MSDOS. The FILES parameter in the CONFIG.SYS file should be reviewed. See page 9.19 in the MSDOS version 2.0 Heath Manual for details. This program can use as many as four files at one time, and the CONGIF.SYS file should be set for 4 or more FILES. OPERATION: When calling up RTY.EXE for the first time, the first thing that will be shown is the "TITLE SCREEN". Hit any key, and the "CONFIGURATION" screen will be available. Enter the values on this screen to fit your requirements and station hardware. This builds a configuration record which can be saved on disk by pressing the "f7" key. The next time the program is called, this configuration record will be read from disk. Page 2 - RTTY 2200 IBM PC (MSDOS) CONFIGURATION ITEMS: Using all capital letters, fill in the items shown on the screen, customized as desired. ITEM: COMMENTS: File Name for Sending: File name of file to be sent or saved with "Alt-N" File Name Disk Out: File name for file copy Max File Size: File copy max size Margin: Custom left margin Baud Rate Index (RTTY): Index from chart at right Transmit Line Length: Length of line sent Call Sign: Your station call sign Time Zone: Your time zone Pace: Delay between chars sent Length of Diddle: Number of chars in callup diddle line RTTY Port (A or B): Port A=COM1, B=COM2 ASCII Printer Port (A, B, or Z): Which port for Printer? Baud Rate Index (Printing): From index at right Printer Ready Low(Y or N) DTS High="N" Printer Line Length: How long a printer line Print Received (Y or N): Print incoming data Print Sent (Y or N): Print outgoing data Disk Out Mode ( R, T, B, of N): What do you want to copy? Pix Mode (Y or N): Pix, anyone? Auto Run Mode: Start with RUN SCREEN New Line for BAUDOT: What will you have? New Line for ASCII: Ditto. Screen Saver: "Y" for 10 min. blank Split Line Location: Split line location WRU on callsign only (Y or N): Yes=response on ZW only Page 3, RTTY 2200.00 IBM PC (MSDOS) DISCUSSION: DISK COPY: This program can "LOG" both incoming and outgoing copy. In the field "DISK OUT MODE", "R" means "RECEIVE", "T" means "TRANSMIT", "B" means "BOTH" and "N" means "NEITHER". If this field has been programmed "N", and when in "RUN", the CONTROL-Y is pressed, the "N" will change to "R". "DISK COPY MODE" comes up automatically if "CONFIGURED" for "R","T" or "B" and a fname.ext has been entered in the "DISK COPY" field. It is suggested that a fname.ext such as "JAN01.AAA" be used so that each day's DISK COPY can be easily identified. MAX DISK OUT SIZE: The number of characters for a disk output file can be specified, to allow editing of the file by small editors. When the output file reaches this size it is closed and another is opened, with an incremented fname.ext. If set to zero of blank, then the maximum will be the amount of space left on the disk. FILE NAMES : All disk file names can include directory names. The only restriction is that the fully qualified name length can be no more than 26 characters. For directory display, a path name can be used and all files at the end of that path name are listed. A blank path name defaults to the current drive and directory. If all files on a non-default drive are to be listed, then the colon must be used. e.g. "d:" OUTPUT FILE NAME: The output file name is incremented in the last character shown, even if there is no extension. e.g. FILEA, FILEB, FILEC,......,FILEZ if named without an extension. FILEA.RYA, FILEA.RYB,......,FILEA.RYZ if named with an extension, such as RYA... END OF LINE SEQUENCES: This controls the sequence sent whenever a new line is started from the transmitted text. It is triggered by the RETURN key, automatic wrap of a line being entered into the buffer, or by a NEWLINE (0AH, same as LINE FEED) character from a disk input file. Baudot allows CARRIAGE RETURN (CR), LINE FEED (LF), LETTERS (LTRS), or FIGURES (FIGS). ASCII allows CARRIAGE RETURN (CR), LINE FEED (LF), or NULL (00H). If left blank, the default sequence is LINE FEED (one). PROGRAMMABLE LINES: Program the "PROGRAMMABLE LINES "A" and "B". Line "A" and "B" will be put into the "CONFIGURATION" record, but each can be changed by going to the "CONFIGURATION" screen at any time. Page 4, RTTY 2200.00 IBM PC (MSDOS) AUTO RUN: A new option has been added on the CONFIGURE screen that allows specifying "AUTOMATIC or MANUAL" operation, when the program is called. This will make possible the automatic re-booting of the program, after a power glitch or failure, and continued operation of the RTY program. The RTY program will start with the RUN screen, if the item "AUTO RUN MODE" is a "Y". To modify the configuration, the CONFIGURE screen is still available by hitting the F1 key. Of course, the RTY program must be called from an "AUTOEXEC.BAT" file, for the "AUTO RUN MODE" to be effective, upon a re-boot. BAUD RATES: The lower right corner of the screen will show "Receive Mode" if receiving and "Send Mode" if transmitting. Just to the left of the Mode indication there will be a letter "B" or "A" and a baud rate.These are from the configuration screen and indicate Baudot or ASCII and the baud rate for the RTTY input and output speed. The input and output speed can be set from the "RUN" screen by hitting keys "f2 or f3". f2 will program 45 baud BAUDOT, and f3 will step through all the normal BAUDOT and ASCII baud rates. PRINTER: If the printer has been programmed "ON" and the middle of the 24th line shows "PRINTER", this means that the printer is either not "READY" of the "HANDSHAKE" line is not properly set. 3RD AND 4TH LEVEL OPERATION: One of the newest features of this program is called "3rd and 4th level BAUDOT". This is a programming method of sending the full ASCII character set over a BAUDOT channel. This program always transmits with 3rd and 4th level characters, and is always available. Unlock the "CAPS LOCK", to send lower case data. The print on a TTY machine, or on a CRT (with other than this program), will show as if it were normal Baudot. Of course, normal ASCII at 100 WPM can also be used, if desired. Toggle 3rd and 4th level receive by hitting the "f7 key", (while in RUN) and note the "3/4" on the left of the Split line, which means that the 3rd and 4th level receive is active. The program comes up in 3/4 mode. Irv Hoff's IRTTY HDOS program will receive 3rd and 4th level BAUDOT and some of his HDOS and CP/M drivers will send 3rd and 4th level. DISK OPERATIONS: When using "DISK COPY or DISK TRANSMIT", a word in the left half of the 24th line will show "IN" or "OUT", meaning "Disk INput of Disk OUTput". If there is an error, then the error will be indicated next to the "IN" or "OUT" depending on which has the problem. Page 5, RTTY 2200.00 IBM PC (MSDOS) From the "RUN" screen, "Alt-N" will allow you to enter a "d:fname.ext" to send without going to the "CONFIGURE" screen. The entry made will be placed into the field called "Filename for Sending". End by typing RETURN. "CTRL-D" calls up the file to be sent, and a second "CTRL-D", stops or aborts the file. Call up the file where ever in the pre-typing or transmit, the file should be sent. SAVE PRE-TYPE BUFFER TO DISK. Prepare the doc in the pre-type buffer that you wish to put into a special fname.ext file. Then hit "Alt-N", and then follow directions on the lower area of the screen. The contents of the pre-type buffer will remain unchanged but the data will be written to the disk. The pre-type buffer can then be cleared by typing "Alt-V". After that, the file can be reloaded, at any time to send it, by typing "CRTL-D" in the normal manner. DELETE FILE FROM DISK. To delete a file from disk, hit the "Alt-N", and follow directions given on the lower lines. HELP SCREEN: From the "RUN" screen, hit "Alt-H" to see all of the programs controls that are available. Type "RETURN" to exit the Help screen. No incoming data will be lost when looking at the control menu. The unsent pre-type data will be scrolled back into the pre-type area when the "RETURN" is hit. Transmit will stop while in the "HELP" screen, but will resume when "RETURN" is hit. DISPLAY OF DISK DIRECTORY. Type "CTRL-A" while the "HELP" screen is displayed. Then type the ID (in UPPERCASE) of the drive on which there is a disk mounted, that you want to display the directory.Type "A","B","C", or "D" for the MS-DOS drive directory. Type "RETURN" to return to the "HELP" screen, and a second "RETURN" to return to the "RUN" mode. FAST BREAKIN: This mode is toggled by "Alt-B". The letters "bk" will appear on the left of the split line, when operating "BREAKIN". The "CTRL-G" will send "-BK-", and turn off the transmitter with out the 4 N's. "CTRL-X" will send only 4 diddles, and then the pre-typed data, when in this mode. Do not use "BREAKIN" mode unless you are truely using "BREAKIN" as most demodulators can not start printing with so few start-up diddles. RELAY: In the "RELAY" mode, there is a timer to prevent untransmitted relay messages to linger in the Pre-type buffer. Ths timer is one hour long, which prohibits any relay message longer than 30 minutes. If the timer expires, the relay message is cleared and the relay function is armed for another usage. Page 6, RTTY 2200.00 IBM PC (MSDOS) NOTE: To use the relay system, follow these steps: 1. Send call of station having a RTY program operational with ZC. callsignZC "CR" (puts relay station into RELAY MODE) callsignZC "CR" (send a second time to assure reception) 2. Send normal message to station: "W0NW de W0SE etc." 3. Send "CR" then "four N's" and a "CR" 4. Send call of station being used for relay,with ZR callsignZR (tells relay station to relay) 5. Hit CTRL-V to leave the air immediately 6. Watch relay being made. PIX: In the "PIX MODE", the "UNSHIFT ON SPACE" is disabled. The shift stays the same as it was before the space. BUFFERS: Depending of the amount of RAM available, the size of the buffers is displayed at the bottom of the "CONFIGURATION" screen. There are three buffers of this size: Received Characters, Pretype for sending, and DISK OUTPUT. LENGTH OF DIDDLE: The number of diddles (LTRS in BAUDOT, NULL in ASCII), sent at the start of each "non break-in" mode transmission, can be specified. The value can be from 1 to 99, and if left blank or set to zero, then the default value of 32 is used. WRU on CALLSIGN: If this item is set to "Y", the WRU will not respond to the :DISK of :TIME command, but only to callsignZW. This mode is indicated on the left of the split line by a reverse video "I". A count is kept of the number of times a WRU is requested of the station (whether it is sent of not). The count is dis- played on the right of the split line. This count will alert the operator of possible messages in the copy. PACE: To smooth out the transmitted output, when a slow typist is typing in "real time", a delay between characters can be programmed on the line called "PACE". Any number from blank to 999 will add from none, to 999 millaseconds between characters, thus smoothing out the output. Characters are still send at the programmed rate, but the average speed is reduced to smooth out the typing.

The function will only work when this version of the RTY program is in use at the relay station and the remote station. Any local station can activate the function. By the use of specific "Z" signals, a remote, but unheard station, can be triggered to send its WRU, through a relay station, and thus be heard by the originating station. Following is the procedure to activate this feature: ------------ ----------- ----------- : Original : : Relay : : Remote : : Station :----\---: Station :-----\----: STATION : : : : : : : ------------ ----------- ----------- Callsigns: aaaaa bbbbb ccccc Action: Comments: aaaaa Sends: Calling station bbbbbZLccccc<ret> Request bbbbb to call WRU NNNN Hit CTRL-G, for NNNN's - bbbbb Sends: Response from bbbbb cccccZMbbbbb Ask ccccc to relay WRU NNNN Normal 4 N's - ccccc Sends: Response from ccccc bbbbbZC Set relay at bbbbb WRU for ccccc Normal WRU from ccccc bbbbbZR Request bbbbb relay - bbbbb then relays the WRU of ccccc, for all to hear. - No operator intervention is required at any station, other than at the originating station. The remote station must be "ON", and its Pre-type buffer empty. Have FUN!!!! And have any kind of a day you would like..... de W0SE AND W0NW...
