My first posting of the PK232 Command List (in uuencoded format) looks like it got trashed. I received numerous requests for a mailing of the ASCII version, so I am posting the ASCII in 4 parts. This posting contains PART 1. Combine the parts as you see fit. Please feel free to upload the file to local packet BBS's or USENET sites where it will be available to PK232 owners. \paul WA3TLD ------------------------------------------------------------------------- PK232CMD.LST PART 1 ------------------------------------------------------------------------- The following information was obtained from the AEA PK232 Operations Manual, the PK232 Technical Reference Manual, and the various updates that were supplied with firmware upgrades. The reason for compiling this listing was my need to have one combined reference for the entire PK232 command set in electronic form which could be searched or read from within a terminal program. The PK232 command listing is plain vanilla ASCII with no hidden control codes or formatting instructions. I have contacted AEA, and they have given me permission to release this information in electronic form, provided that it is placed into the public domain and not sold. There is no information in this listing that cannot be obtained from one of the AEA documents or manuals for the PK232; this listing just makes it a little easier to search/find info on particular PK232 commands options etc. I have made reasonable effort to insure that the information contained in the listing is correct and accurate. I DONNN'TT Makee Mastakes. If you find one, PLEASE send your correction to: pauld@fs1.ece.cmu.edu or paul+@andrew.cmu.edu or WA3TLD @ NO3M.#WPA.PA.USA.NA Enjoy! \paul Paul Dujmich 2103 Hammerschlag Hall Dept. of Electrical and Computer Engineering Carnegie Mellon University 5000 Forbes Ave. Pittsburgh, PA. 15213 ============================================================================ PK232 COMMAND SUMMARY (Version 1.0 4-30-91) ========================= MULTIMODE COMMANDS ========================== AAB text Default: empty Modes: Baudot, Ascii, Amtor text = any ascii text up to 17 characters. AAB sends "text" automatically in response to a "WRU" command from the distant station. ACRDISP 'n' DEFAULT: 80 MODES: ALL 'n' = 0 to 255 'n' specifies the screen or printer width (in columns). '0' disables this function. After 'n' characters have been printed, the PK232 sends a <CR><LF> sequence to the computer or terminal. For MORSE Mode: Received data will be broken up into word boundries if possible. PK232 generates a <CR> when the first space is received after column X. If ALFDISP is also on, PK232 also generates a <LF>. Column X is 12 less than the ACRDISP value. If ACRDISP is set to 0, then column X = 60. ACRRTTY 'n' DEFAULT: 71 (69 in AMTOR) MODES: Baudot, Ascii Rtty 'n' = 0 to 255 'n' specifies the number of characters on a line, after which, a <CR> is automatically inserted in the transmitted text. '0' disables this function AFILTER (ON/OFF) DEFAULT: OFF MODES: ALL ON - The ASCII characters specified by MFILTER are filtered out and never sent to the terminal or computer. OFF - Characters specified by MFILTER are only filtered from monitored packets. If ECHO is ON, and the terminal or computer sends a filtered character, the PK232 WILL echo it back to the computer or terminal. CAUTION: AFILTER must be OFF for binary file transfers. ALFDISP (ON/OFF) DEFAULT: ON MODES: All ON - A line feed <LF> character is sent to the terminal after each carrage return <CR> character. Each line feed received is ignored. OFF - A <LF> is not sent to the terminal after each <CR> Affects the local display only, and does not affect the data transmitted in any mode. Affects received packets as well as text typed in. ALFRTTY (ON/OFF) DEFAULT: ON MODES: Baudot, Ascii Rtty ON - A <LF> character is sent after each <CR> character. OFF - A <LF> is not sent after each <CR> AWLEN 'n' DEFAULT: 7 MODES: All 'n' = 7 or 8 'n' = number of data bits per word The 'RESTART' command must be issued before a change in word length will take effect. BKONDEL (ON/OFF) DEFAULT: ON MODES: All Determines how character deletion is displayed in command or Converse modes. ON - The sequence <BACKSPACE><SPACE><BACKSPACE> is echoed when a character is deleted from the input line. OFF - The <BACKSLASH> <\> character is echoed when a character is deleted from the input line. Set to 'ON' for video terminals or computers. Set to 'OFF' for printers. CALIBRATE Starts the modem calibration routine. PK232 shows on screen display of AFSK generator tone frequencies (in Hz). The frequency and calibration pot number associated with that tone are displayed. Commands: K - Toggles transmitter PTT line on and off. Q - Quits the calibration routine. H - Toggles the transmitted audio tones between wide shift (1000 hz), and narrow shift (200 hz). SPACE> - Toggles the transmitted audio tone between MARK (low tone), and SPACE (high tone). D - Alternates the transmitted mark and space tones at a rate set by the radio (HB) baud rate. 'D OFF' transmits a continuous mark or space tone. CANLINE 'n' DEFAULT: $18 <CTRL-X> MODE: All 'n' = $00 to $7F (0 to 127 decimal) 'n' specifies an ASCII character code. Sets the CANCEL-LINE input editing command character. When CANLINE is used, the current line is terminated with a <\>, and a new command prompt appears. CCITT (ON/OFF) DEFAULT: ON MODE: Baudot Rtty. ON - Characters typed or loaded from disk are translated into CCITT International Telegraph Alphabet #2 before being sent. OFF - Characters sent to PK232 are not translated, but remain in the American standard Baudot format (Typically Western Union). CODE n DEFAULT: 0 MODES: Baudot, AMTOR, MORSE n = 0 to 5 specifies a code to use. CODE Meaning MORSE BAUDOT AMTOR --------------------------------------------------------- 0 International RX/TX RX/TX RX/TX 1 U.S Teleprinter - RX/TX - 2 Cyrillic RX RX RX 3 Transliterated Cyrillic RX RX RX 4 Katakana RX/TX - - 5 Transliterated Katakana RX - - (See pages N-4 - N-7 for more details concerning codes) COMMAND 'n' DEFAULT: $03 <CTRL-C> MODES: All Used to change the command mode entry character. 'n' = $00 to $7F (0 to 127 decimal) 'n' specifies an ASCII character code. CONVERSE MODES: All Causes the PK232 to switch from command mode to converse mode. Link connections in packet and AMTOR are not affected. CRADD (ON/OFF) DEFAULT: OFF MODES: Baudot Rtty Permits you to setup the PK232's newline sequence so that an additional carrage return as added automatically at the end of each typed line. ON - Send <CR CR LF> in Baudot Rtty OFF - Send <CR LF> in Baudot Rtty The double CR is required in some rtty services such as in MARS operation. CWID 'n' DEFAULT: $06 <CTRL-F> MODES: Baudot/ASCII Rtty/AMTOR Lets you change the 'send cwid' control character, typed at the end of a Baudot or ASCII Rtty or AMTOR keyboard diaglog, or text file stored on disk. When character 'n' is seen by the PK232, it switches to CW mode, and sends your call sign at the speed set by MSPEED. After call sign has been sent, PK232 returns to Baudot or ASCII Rtty receive, in command mode. CWID ON Activates this function. CWID OFF deactivates the function. DAYTIME date&time DEFAULT: Not set MODES: All Sets the PK232 internal clock to the current date and time. Format for entering date and time: DAYTIME YYMMDDhhmm (year, month, day, hour, minute) All codes must have 2 digits. For numbers 0-9 add leading zeros. If DAYTIME has not been set, and a <CTRL-T> is pressed, PK232 sends an <*>. DAYSTAMP (ON/OFF) DEFAULT: OFF MODES: All Activates the date in CONSTAMP and MSTAMP. ON - The date is included in CONSTAMP AND MSTAMP OFF - Only the time is includes in CONSTAMP and MSTAMP DCDCONN (ON/OFF) DEFAULT:OFF MODES: Packet and AMTOR Defines how the DCD (Data Carrier Detect) signal affects pin 8 of the RS-232 interface. ON - RS-232 cable pin 8 follows the state of the CON LED. OFF - RS-232 cable pin 8 is permanently set high (active) DELETE (ON/OFF) DEFAULT: OFF MODES: All Selects the key to use for deleting while editing. ON - <DELETE> ($7F) key is used for deleting text. OFF - <BACKSPACE> ($08) is used for deleting text. BKONDEL command controls how the PK232 indicates deletion. You cannot use the DEL key to delete text before the beginning of a line. Use the PASS character to delete <CR> characters that have been typed into the text. To see a corrected display of the edited line, use the redisplay-line character which is set by the REDISPLAY command. DIDDLE ON/OFF (DEFAULT OFF) MODES: Baudot, ASCII ON - In Baudot, PK232 sends LTRS character while idling. In ASCII, PK232 sends NULL ($00) while idling. OFF - No characters are sent while idling in transmit. DISPLAY [class] MODES: Command Mode 'class' can be one of the following: (A)sync Display asynchronous port parameters. (C)character Display special characters. (F)ax Display Facsimile parameters. (I)d Display ID parameters. (L)ink Display Link parameters. (M)onitor Display monitor parameters. (R)tty Display Baudot/ASCII/RTTY, AMTOR and MORSE parameters. (T)iming Display timing parameters. (Z) Display the entire command parameter list. EAS (ON/OFF) DEFAULT: OFF MODES: Baudot, ASCII Rtty, AMTOR and MORSE ECHO AS SENT functions in all modes except PACKET. ON - Display characters as actually sent on the air by PK232. OFF - Display characters as sent to the PK232 by the computer. If EAS is ON, only upper case characters will be displayed, representing the actual data sent to the distant station. For AMTOR Mode A (ARQ) - If EAS is ON, characters are displayed on the screen ONLY after they are Ack'd by the distant station, no matter how fast you type, (3 at a time). Nulls ($00) are not echoed. ECHO (ON/OFF) DEFAULT: ON MODES: All Controls local echoing by the PK232 when it is in command or converse mode. Local echoing is disabled in TRANSPARENT mode. ON - Characters received from the computer ARE echoed by the PK232. OFF - Characters are not echoed. ESCAPE (ON/OFF) DEFAULT: OFF MODES: ALL Selects the character to be output when an <ESCAPE> character is to be sent to the terminal. ON - The <ESCAPE> character, ($1B) is output as "$" ($24) OFF - The <ESCAPE> character is output as <ESCAPE> ($1B) FLOW (ON/OFF) DEFAULT: ON MODES: All ON - Flow control is active. Any character typed on the keyboard causes output from the PK232 to the terminal to stop until any of the following conditions exist: 1. A packet is forced in CONVERSE mode. 2. A line is completed in COMMAND mode. 3. The packet length (PACLEN) is exceeded. 4. The terminal output buffer fills up. OFF - Type in flow control is NOT active. FULLDUP (ON/OFF) DEFAULT: OFF MODES: ALL ON - Full Duplex mode is ENABLED. OFF - Full Duplex mode is DISABLED. When full duplex is DISABLED, the PK232 uses the DCD (data carrier detect) signal from it's modem to avoid collisions. PK232 acknowledges multiple packets in a single transmission with a single acknowledgment. When full duplex is ENABLED, PK232 ignores the DCD signal, and acknowledges packets individually. HELP MODES: ALL Displays the more important PK232 commands. HEREIS 'n' DEFAULT: $02 (CTRL-B) MODES: BAUDOT, ASCII, AMTOR n = hexidecimal representation ($01-$7F) that causes the AAB string to be sent in the middle of transmitted text. HOST (ON/OFF) DEFAULT: OFF MODES: ALL Puts PK232 in 'host mode'. ON - PK232 goes into HOST mode. OFF - PK232 operates as a normal TNC. To exit host mode, send: 3 <CTRL-C> characters or type <CTRL-A> O H O N <CTRL-W> Sending a BRK signal will not exit PK232 from host mode. Turning the PK232 on or doing a RESTART command while in HOST mode causes the TNC to issue a RESTART response ($01 $4F R T $00 $17) LOCK MODES: MORSE/Baudot/AMTOR/FAX Instructs the PK232 to measure the speed of the received MORSE code signals, and lock it's timing to the speed of the incoming signals. LOCK also forces LETTERS shift in Baudot and AMTOR modes. MFILTER n1 [,n2 [,n3 [,n4 ]]]] DEFAULT: $80 MODES: MORSE/Baudot/ASCII/AMTOR/PACKET n = $00 to $80 (0 to 128 decimal) n specifies an ASCII character code. Up to 4 characters may be specified. n = $80 (Special Value) - All characters in the range $80 to $FF, as well as control characters , except for <CR> ($0D), Linefeed <LF> ($0A), and TAB ($09), are filtered out and not sent to the terminal or computer. MARSDISP (ON/OFF) DEFAULT: OFF MODES: Baudot and AMTOR RTTY. Permits the operator to detect and display every character, including LTRS and FIGS codes sent by the other station. ACRDISP and ALFDISP can be turned off to prevent carrage returns and line-feeds from being sent to the RS-232 port. ON - PK232 translates LTRS character to a <CNTRL-O> and FIGS character to a <CTRL-N> and sends these to the terminal. OFF - PK232 does not display LTRS and FIGS codes. MWEIGHT 'n' (DEFAULT: 10) MODES: ALL except PACKET n = 5 to 15 Specifies the ratio of dot length to inter- element space length. n = 10 results in a 1:1 dot space ratio. n = 5 results in a .5:1 dot space ratio. n = 15 results in a 1.5:1 dot space ratio. MWEIGHT applies to MORSE mode, and to the CW id's of all other modes EXCEPT PACKET. NEWMODE (ON/OFF) DEFAULT: ON MODES: ALL Determines how the Pk232 behaves when the link is broken. ON - PK232 returns to command mode upon disconnect. OFF - PK232 does not return to command mode upon disconnect. NOMODE (ON/OFF) DEFAULT: OFF MODES: ALL ON - NEWMODE function is ignored, OK232 switch mode commands work only upon explicit command. OFF - PK232 changes mode according to NEWMODE. NUCR (ON/OFF) DEFAULT: OFF MODES: All Causes the PK232 to send <NULL> characters ASCII ($00), to the computer or terminal. This function permits the PK232 to be used with a Teletype machine or other mechanical type of terminal that requires a time delay after a <CR> is sent from the PK232. The time delay gives the mechanical carrage time to return to the home position. ON - <NULL> characters are sent to the terminal following a <CR> character. OFF - <NULL> characters are not sent to the terminal following a <CR> character The NULLS command sets the number of individual nulls to be sent for the NUCR command. NULF DEFAULT: OFF MODES: ALL ON - <NULL> characters are sent to the terminal following a <LF> character. OFF - <NULL> characters are NOT sent to the terminal following a <LF> character. This command sends the <NULL> character ($00) to the terminal or computer after every <LF> character. This function permits the PK232 to be used with a Teletype machine or other mechanical type of terminal that requires a time delay after a <LF> is sent from the PK232. The time delay gives the mechanical carrage time to perform a line feed. The NULLS command sets the number of null character that will be sent after each <LF> character. NULLS 'n' DEFAULT: 0 (zero) MODES: All Specifies the number of <NULL> characters ($00) that will be sent to the terminal after a <CR> or <LF> is sent. 'n' = 0 to 30 number of nulls to be sent. Nulls are sent from the PK232 to the terminal only during converse and command modes. NUMS MODES: Baudot, AMTOR Forces PK232 into Figures case in Baudot and AMTOR receive. OPMODE MODES: ALL Shows the current PK232 mode of operation and system status. PARITY 'n' DEFAULT: 3 (even) MODES: ALL 'n' = 0 to 3 selects a parity option. 0 = no parity 1 = odd parity 2 = no parity 3 = even parity The parity bit is stripped automatically on input and is not checked in command and converse modes. In TRANSPARENT mode, all 8 bits, including parity, are transmitted in packets. When no parity is selected, and AWLEN is 7, the 8th bit is sent as a "0". PROUT (ON/OFF) DEFAULT: OFF ON - All text characters, including terminal echoes, are sent to the parallel printer if PRCON is also ON. Keyboard input is still accepted. OFF - All text and data is sent to the terminal through the serial port. This command is useful when using a dumb terminal with the PK232 for getting a hard printed copy of what is being received by the PK232. RCVE MODES: Baudot and ASCII Rtty Switches PK232 from transmit to receive, when used in the command mode. (CTRL-C enters the command mode) RECEIVE 'n' DEFAULT: $04 <CTRL-D> MODES: Baudot/ASCII/MORSE/AMTOR 'n' = 0 to $7F (0 to 127 decimal) 'n' specifies an ASCII character code The RECEIVE command let's you specify a character that can be inserted in your typed text or disk file. When this character is read by the PK232, PK232 switches from transmit to receive, and returns to command mode. REDISPLA 'n' DEFAULT: $12 <CTRL-R> MODES: All 'n' = $00 to $7F (0 to 127 decimal) 'n' is the ASCII code for the character you'll use to re-display the current input line. REDISPLA causes the line you just typed to be re-displayed. RESET MODES: ALL Resets all parameters in the PK232 to default prom settings. All personalized parameters are LOST. RESTART will reinitialize the PK232 from battery backed up ram, keeping all the user personalized parameters. RESTART MODES: ALL Reinitializes the PK232 using the defaults stored in the battery backed up ram. RESTART has the same effect as turning the PK232 off then back on. RXREV (ON/OFF) DEFAULT: OFF MODES: Baudot/ASCII/AMTOR ON - Received data polarity is reversed (mark-space reversal). OFF - Received data polarity is normal. Type "RXREV TOG" to toggle the polarity of the received signal when trying to decode an unknown Baudot signal. SIGNAL MODES: ASCII/AMTOR/BAUDOT Causes Pk232 to enter the SIAM Signal Analysis mode. After about 10 seconds, the screen will display the predicted signal type and confidance factor. The signal type can be ASCII, AMTOR, ALIST, Baudot, synchronous, noise, 6-bit. The confidance factor ranges from 0.1 to 0.99. START 'n' DEFAULT: $11 <CTRL-Q> MODES: ALL 'n' = $00 to $7F (0 to 127 decimal) 'n' specifies an ASCII code for the User Start character that you want to use to restart the output from the PK232 to the terminal, after it has been halted by the User Stop character. STOP sets the User Stop character. If User START or User STOP characters are $00, then software flow control to the PK232 is disabled. PK232 will then respond only to hardware flow control, (CTS). If the same character is used for both START and STOP character, then the PK232 toggles between start and stop when the character is read. --------------------------------------------------------------------------- PK232CMD.LST (PART 2) --------------------------------------------------------------------------- STOP 'n' DEFAULT: $13 <CTRL-S> MODES: ALL 'n' = $00 to $7F (0 to 127 decimal) "n" specifies an ASCII character code for the User STOP character. (See explination for START). TBAUD 'n' DEFAULT: 1200 bauds MODES: ALL 'n' specifies the PK232 to Computer baud rate. The baud rate set by TBAUD will take effect upon the next power-on or RESTART command. Baud Rates: 45, 50, 57, 75, 100, 110, 150, 200, 300, 400, 600, 1200, 2400, 4800, 9600. TCLEAR MODES: ALL For Baudot/ASCII/AMTOR/MORSE - TCLEAR clears the PK232 transmit buffer and cancels any further transmission of data. For PACKET mode - All data is cleared except for a few remaining packets. TCLEAR must be used from COMMAND MODE. TIME 'n' DEFAULT: $14 <CTRL-T> MODES: ALL 'n' = $00 to $7F ( 0 to 127 decimal) 'n' specifies the control character for embedding the TIME command into your message text or file. At transmit time, the PK232 reads the embedded control code (default = CTRL-T), reads the time from the PK232 internal clock, and then sends the time to the radio in the data transmission code currently in use at the time. If DAYSTAMP is ON, the date is transmitted with the time. TRACE (ON/OFF) DEFAULT: OFF MODES: PACKET/FAX ON - Trace function is activated. OFF - Trace function is disabled. Activates AX.25 protocol display. When TRACE is ON, all received frames are displayed in their entirety, including all header information. (See pg 6-101 of manual for more details). If TRACE is ON, PRFAX is OFF and the mode is FAX, the graphics escape sequences and dot data are sent to the terminal with each byte expanded to 2 hexadecimal characters (ascii hex dump). This gets around the limitation of many terminal programs, that do not allow 8-bit data to be saved to disk as an ASCII file. A small program could be used to re-translate the ascii hex back into a binary file. (pg M-29 of Pk232 manual has small IBM Basic program to do this.) TRFLOW (ON/OFF) DEFAULT: OFF MODES: ALL ON - Software flow control for the computer or terminal can be activated in Transparent mode. OFF - Software flow control for the computer or terminal is disabled in Transparent mode. If TRFLOW is ON, START and STOP determine the flow control characters to use for software flow control in Transparent mode. If TRFLOW is OFF, Only hardware flow control is available to the computer, (RTS, CTS). All characters received by the PK232 are transmitted as data. TXDELAY n DEFAULT: 30 MODES: Packet, Baudot, and ASCII. n = 0 to 120 ten millisecond intervals. TXDELAY sets the delay between PTT and and the start of transmitted data. ARQ still uses ADELAY. TXREV (ON/OFF) DEFAULT: OFF MODES: Baudot/ASCII/AMTOR ON - Transmit data polarity is reversed. (mark-space reversal). OFF - Transmit data polarity is normal. If TXREV is ON, mark and space are reversed in the AFSK and FSK transmitted signals. WIDESHFT (ON/OFF) DEFAULT: OFF MODES: Baudot/ ASCII Rtty ON - RTTY tones are shifted 1000 Hz. OFF - RTTY tones are shifted 200 Hz (emulates 170 Hz shift). WORDOUT (ON/OFF) DEFAULT: OFF MODES: All modes except PACKET. Determines whether or not you can edit while entering text for transmission. ON - Typed characters are held in the transmit buffer until a space character or punctuation is typed. OFF - Typed characters are sent directly to the transmitter. The ENQ character ($05) <CTRL-E> will also cause the release of a word, as will space, CR, LF, tab, RECEIVE or CWID character. WRU (ON/OFF) DEFAULT: OFF MODES: Baudot/ASCII/AMTOR ARQ ON - Your answerback is sent after a distant station's WRU? OFF - Your answerback is not sent after a distant station's WRU? If WRU is ON, PK232 sends the text in AAB text field. In AMTOR ARQ, your answerback will automatically send "+?", the changeover command, to the distant station to maintain the link. NOTE: In AMTOR, WRU is ALWAYS ON. XFLOW (ON/OFF) DEFAULT: ON MODES: ALL ON - XON/XOFF software flow control is activated. OFF - XON/XOFF flow control is disabled. Hardware flow control is enabled. If XFLOW is ON, the terminal or computer is expected to respond to the PK232 START and STOP characters defined by the XON and XOFF commands. If XFLOW is OFF, the PK232 sends hardware flow commands via the RTS hardware line. For full hardware control in BOTH directions, set START, STOP, XON, and XOFF to $00. XOFF 'n' DEFAULT: $13 <CTRL-S> MODES: ALL 'n' = $00 to $7F (0 to 127 decimal) Selects the STOP character to be used to stop input from the computer or terminal. XON 'n' DEFAULT: $11 <CTRL-Q> MODES: ALL 'n' = $00 to $7F (0 to 127 decimal) Selects the PK232 START character that is sent to the computer or terminal to restart input from that device. ========================= PACKET COMMANDS ============================= 3RDPARTY ON/OFF DEFAULT:OFF ON - The Mailbox BBS will handle 3rd party traffic. OFF - This feature is disabled. 8BITCONV (ON/OFF) DEFAULT: OFF Permits packet transmission of 8 bit data in Converse Mode. ON - The high order bit is not stripped in Converse Mode. Off - The high order bit is stripped in Converse Mode ACKPRIOR ON/OFF DEFAULT: OFF ON - Priority acknowledgement is enabled. When a busy channel condition clears (DCD LED OFF), DATA Acknowledgements will be sent immediately, while data and poll bits are held off long enough to prevent collision with the data acks. ACKS are given priority so that fewer acks will collide with data from other stations preventing useless retries. Digi-peated frames are still sent immediately. OFF - This feature is disabled. ACRPACK (ON/OFF) DEFAULT: ON ON - The send packet character (normally <CR>, is added to all packets sent in Converse Mode. OFF - The send packet character is not added to packets. ALFPACK (ON/OFF) DEFAULT: OFF ON - A <LF> character is added to outgoing packets following each <CR> transmitted in the packet. OFF - A <LF> is not added to outgoing packets. Affects outgoing packets only, does not affect the local display. AUDELAY 'n' Sets delay between PTT going active, and the start of transmit AFSK audio tones. n = 0 to 120 (10 ms intervals). AUDELAY must always be less than TXDELAY by a setting of 10. AX25L2V2 (ON/OFF) DEFAULT: ON ON - PK232 uses AX.25 Level 2 Version 2.0 protocol OFF - PK232 uses AX.25 Level 2 Version 1.0 protocol AXDELAY 'n' DEFAULT: 0 'n' = 0 to 180 'n' = specifies a keyup delay for voice repeater operation in ten-millisecond intervals. Causes PK232 to wait for a delay period (in addition to TXDELAY), after keying the transmitter, and before data is sent. AXHANG 'n' DEFAULT: 0 'n' = 0 to 20 'n' specifies a voice repeater hang time in 100 mili-second intervals. BBSMSGS (ON/OFF) DEFAULT: OFF ON - Makes the PK232 status messages look like the TAPR style output. OFF - The PK232 status messages work as before. BEACON EVERY|AFTER 'n' DEFAULT: 0 Sets the condition under which the packet beacon will be transmitted. EVERY - Send the beacon at regular intervals. AFTER - Send the beacon once after that specified time interval without packet activity. 'n' = 0 to 250 'n' sets beacon timing in ten second intervals. '0' Turns off the beacon completely. A beacon frame includes the text you enter with the 'BTEXT' command. The Beacon packet is addressed to 'CQ' or other address specified by 'UNPROTO'. BTEXT text DEFAULT: Empty Sets the text portion of the beacon packet. text = up to 120 characters and spaces. A multiple line message can be sent by including a <CR> character in the text. <CR> is inserted by typing the PASS character before the <CR>. The PASS character is sent by the PASS command. '%', '&', 'N', 'NO', 'NONE', or 'OFF' will clear the BTEXT text. CANPAC 'n' DEFAULT: $19 <CTRL-Y> Sets the CANCEL-PACKET input editing command character. 'n' = $00 to $7F (0 to 127 decimal) 'n' specifies an ASCII character code. Only a packet that is currently being entered can be canceled. When a packet is cancelled, the line is terminated by a <\> and a <NEWLINE>. The CANCEL-PACKET character also cancels the display output in Command Mode. Type CANCEL-PACKET again to restore the display output. CASEDISP 'n' DEFAULT: 0 (as is) Sets the case of the characters that the PK232 sends to the terminal. 'n' = 0 'As is' characters are not changed. 'n' = 1 'lower' characters are displayed in lower case only. 'n' = 2 'UPPER' characters are displayed in upper case only. CBELL (ON/OFF) DEFAULT: OFF ON - Three bell characters ($07 CTRL-G) are sent to the terminal with the **** CONNECTED TO, or ****DSCONNECTED FROM messages, when a connection is established, or terminated. OFF - Bell characters are not sent with the connect message. CBELL sends bell characters on disconnect as well as connect. CFROM all, none, yes/no, call1 [call2..] DEFAULT: All Determines how PK232 responds to connect requests. call all, none, YES list, NO list (list up to 8 callsigns seperated by comma's) CFROM NONE - rejects all connect requests. CFROM ALL - Accepts all connect requests. CFROM NO call1, call2, call3 ...... CFROM YES call1, call2, call3 ..... CFROM <%> or <&> or OFF clears the CFROM arguments. CHCALL (ON/OFF) DEFAULT: OFF Displays the callsign of the connected-to station after the channel identifier. ON - Call sign of distant station is displayed in multiple connection operation. OFF - Call sign of the distant station is not displayed. CHDOUBLE (ON/OFF) DEFAULT: OFF Displays received CHSWITCH characters as double characters. ON - Received CHSWITCH haracters appear twice. OFF - CHSWITCH characters only appear once. NOTES: Set CHDOUBLE ON when operating with multiple connections, to tell the difference between CHSWITCH characters received from other stations, and those generated by your PK232. CHSWITCH character must not be one of the channel numbers (0-9). CHECK 'n' DEFAULT: 30 Sets a timeout value for a packet connection, and depends on the setting of AX25L2V2. 'n' = 0 to 250 (check time in ten second intervals) 0 = Zero disables this feature. CHSWITCH 'n' DEFAULT: $00 Selects the characters used by both the PK232 and the user to show that a new connection channel is being addressed. 'n' = $00 to $FF (0-255 decimal) 'n' = ASCII character code. CMDTIME 'n' DEFAULT: 10 (1000 ms) Sets the timeout value in TRANSPARENT mode. A guard time of 'n' seconds is allowed to escape from transparent mode to command mode, while permitting any character to be sent as data.

OFF - PK232 does not send HDLC identification. The timing for the identification is every 9.5 minutes, and cannot be changed. ID Sends a special identification packet. (HID must be set ON). Sends a final identification packet when you're taking your station off the air. The identification consists of an un-numbered I frame with it's data field containing your MYALIAS and your MYCALL and the word "digipeater". ILFPACK (ON/OFF) DEFAULT: ON Permits you to control the way the PK232 handles line feed characters received from your computer. ON - PK232 ignores all line-feed characters received from the computer terminal. OFF - PK232 transmits all line-feed characters received from the computer or terminal. ---------------------------------------------------------------------------- PK232CMD.LST (PART 3) ---------------------------------------------------------------------------- KISS (ON/OFF) DEFAULT: OFF KISS protocol eliminates most of the PK232 software, and sends raw HDLC frames up to the host computer. The bulk of AX.25 (or other protocol) must be done on the host computer. ON - PK232 operates as a KISS TNC. Forces HPOLL OFF (temporarily), PPERSIST ON, RAWHDLC ON, and HOST ON. RAWHDLC ON temporarily forces CONMODE TRANS, TRACE OFF, HID OFF, and NO Beacon. HOST ON temporarily forces 8BITCONV ON, AWLEN 8, PARITY 0, and no software flow control. To exit KISS mode, type (3) <CTRL-C> all within 1 second. HOST OFF (3 Ctrl-C's) forces KISS OFF. PK232 CMD and PKT LED's will be lit confirming exit from KISS mode. "Temporarily" means that PK232 will behave as if the function is set that way, even though the function setting does not change. OFF - PK232 operates as a normal AX.25 level 2 TNC. In KISS and Raw HDLC modes, communication activity on the RS-232 link is shown by the illumination of the STA and CON led's as follows: STA led lit: Host to TNC communication. CON led lit: TNC to host communication. KISS mode is used to run TCP/IP. To run TCP/IP, the following parameters must be set: AWLEN 8 PARITY 0 Enter if terminal word length and parity RESTART is something other than 8 bits -------------------------------------------------- TRACE OFF Enter if commands have been HID OFF changed from default settings. BEACON EVERY 0 PACKET --------------------------------------------------- CONMODE TRANS Enter these commands with HOST ON PPERSIST ON command entered last. RAW ON HPOLL OFF KISS ON HOST ON (must be entered last) MAILDROP ON/OFF DEFAULT: OFF ON - PK232 operates as a personal packet BBS. OFF - PK232 operates as normal AX.25 Level 2 TNC. 8000 bytes of ram are available for the mailbox. The ram can be used for a single message or up to 15 messages. Power on/off, RESTART or RESET clears all messages in ram. Mailbox commands: B - BYE Log off the Mailbox K - Kill or delete messages. L - List the message directory R - Read a specific message S - Send a message MAXFRAME 'n' DEFAULT: 4 'n' = 1 to 7 Sets the upper limit on unacknowledged packets the PK232 permits on the radio link at any one time. Also sets the maximum number of packets the PK232 will send during any given transmission. MBELL (ON/OFF) DEFAULT: OFF ON - Will send 3 bell characters to the terminal when the call signs of the station monitored match the MFROM and MTO lists. OFF - PK232 will NOT send any bell characters to the terminal as a result of monitored packets. MBX call1 [,call2] [ -'n'] DEFAULT: empty MBX overrides normal monitor functions so that you can monitor one or both sides of a conversation. MBX filters the received packet stream so that only packets from the selected stations are shown, without headers, codes, or repeated frames. Permits you to read and record data without having to log on or connect to the source station. Use this command if someone is dumping a file on a PBBS, any you would like a clean copy of it. The resulting information is free of all headers, frame identifier codes, repeats and improperly sequenced lines. "ALL" permitts MBX to monitor packets from any station. MBX is cleared with %, &, N, or NO. MCON 'n' DEFAULT: 0 (zero) Allows selective monitoring of a other traffic while connected to a distant station. Affects the display only in the connected state. 'n' = 0 to 6 signifying various levels of monitoring 0 = Disable monitoring while connected. 1 = Show only unnumbered (UI) frames resulting from an unconnected transmission. Also displays beacons. 2 = Numbered (I) frames are also displayed. These result from a connected transmission. Monitors connected conversations in progress. 3 = Connect requests (SABM or 'C') frames and (DISC or 'D') frames are also displayed with headers. 4 = Unnumbered acknowledgment frames (UA) of connect and disconnect state frames are also displayed with either the character (UA) or (DM) and a header. 5 = Receive Ready (RR), Receive Not Ready (RNR), Reject (RJ) Frame Reject (FRMR) and (I)- frames are also displayed. 6 - Poll/Final bit and sequence numbers are also displayed. MDCHECK Logs you on to your own mailbox to check for messages. While you are logged onto the mailbox, any connect request from a distant station will be answered with a "BUSY" (DM) frame to the distant station. If MAILDROP is OFF, you cannot issue mailbox commands. You must use the MDCHECK command . A blinking STA LED indicates that a message has been left for the mailbox owner. MDCHECK turns off the STA LED. You cannot log onto your mailbox while a connect with another station is in progress. MDIGI (ON/OFF) DEFAULT: OFF Permits you to display packet frames that your monitor would normally not show when another station uses your station as a digipeater.

Up to 4 characters can be specified. MFROM ALL/NONE or YES/NO call1 [,call2..] DEFAULT: ALL Determines how the PK232 monitors the packet channels, and displays the information. Determines which station's packets will be displayed, and which station's packets will be hidden. MFROM NONE Stops any packets from being displayed. MFROM YES [call list] displays packets only from stations whose call is in list. MFOM NO [call list] Hides or masks packets from one or more specific stations. Clear MFROM with %, & or OFF. MHEARD Displays a list of stations heard since the last time the MHEARD buffer was cleared. To clear MHEARD buffer use MHEARD &, N, NO, NONE, or OFF. The maximum number of stations that can be logged is 18. As more stations are heard, earlier entrys are discarded. MID 'n' n = 0 to 250 Specifies the Morse ID timing in 10 second intervals. PK232 issues a 20 WPM Morse ID. n = 0 Disables Morse ID (DEFAULT) If HID is ON, ID will cause HDLC ID to be transmitted immediately (same as before). If MID is set to a value other than 0, ID will force a MORSE ID immediately. If both HID and MID are active, the MORSE ID will be sent first. MONITOR 'n' DEFAULT: 4 'n' = 0 to 6 determines various levels on monitor indications. 0 = Disable monitoring while connected. 1 = Show only unnumbered (UI) frames resulting from an unconnected transmission. Also displays beacons. 2 = Numbered (I) frames are also displayed. These result from a connected transmission.

MPROTO (ON/OFF) DEFAULT: OFF ON - Monitors all I and UI frames as before. OFF - Monitors only those I and UI frames with PID byte of $F0. Used with NET/ROM that sends frames that have a PID of $CF. Allows monitoring of frames used by NET/ROM. MRPT (ON/OFF) DEFAULT: ON Affects the way monitored packets are displayed. ON - Show digipeaters in the header. Stations heard directly are marked with an "*" asterisk. OFF - Show packets only from originating and destination stations. MSTAMP (ON/OFF) DEFAULT: OFF Activates or disables time stamping of monitored packets. ON - Monitored frames are time stamped. OFF - Monitored frames are not time stamped. MTO ALL/NONE or YES/NO call1 [,call2...] DEFAULT:none MTO determines how the PK232 monitors the packet channel. It determines which station's packets will be displayed, and which station's packets will be masked off or hidden. MTO ALL Stops all packets to all stations from being displayed MTO YES <call list> will display packets to the stations, whose calls are included in list. MTO NO <call list> Packets to stations whose calls are included in list, will not be displayed. Clear MTO with %, &, or OFF MYALIAS call [-n] DEFAULT: Empty Specifies an alternate callsign or alias for use as a digipeater only. n = 0 to 15 optional substation ID. MYCALL call [-n] DEFAULT: PK232 Loads your call sign into PK232 memory. n indicates an optional substation id (SSID). If MYCALL has not been changed from the default value of "PK232", PK232 will not transmit or acknowledge any packets. This prevents "PK232" from being transmitted. PACKET Causes the PK232 to enter the packet radio mode. PACLEN 'n' DEFAULT: 128 Sets the maximum number of user data bytes to be carried in each packet's information field. 'n' = 0 to 255 data bytes or characters. 0 = is equivalent to 256 NOTE: it is not necessary that two TNC's be set to the same packet length to exchange data. Some TNC's may not be compatible with frames containing more than 128 data bytes. PACTIME EVERY|AFTER 'n' DEFAULT: After 10 (1000 ms) A PACTIME parameter is ALWAYS used in TRANSPARENT mode. PACTIME is also used in converse mode if CPACTIME is ON. 'n' = 0 to 250 specifies number of 100 millisecond intervals. EVERY - packet timeout occurs every 'n' * milliseconds. AFTER - packet timeout occurs when 'n' * 100 milliseconds elapse without input from the computer or terminal. A zero length packet will never be produced. The timer is not started until the first character or byte is entered. A value of 0 for 'n' is not allowed. Zero means packets are sent with no wait time. PASS 'n' DEFAULT: $16 <CTRL-V> Selects the ASCII character code to be used for the pass input editing command. 'n' = $00 to $7F (0 to 127 decimal) ASCII code. 'n' is the numeric ASCII code for the character you'll use to signal that the character immediately following it is to be included in the packet or text string. Use the PASS character (DEFAULT: <CTRL-V)) to send characters that usually have special functions. PASSALL (ON/OFF) DEFAULT: OFF ON - PK232 will accept packets with invalid CRC's. OFF - PK232 will accept packets with valid CRC's ONLY. PASSALL shuts off the error detecting mechanism in packet mode. When PASSALL is ON, MHEARD logging is disabled since the call signs detected may be incorrect. PERSIST 'n' DEFAULT: 127 (middle between 0 and 255) 'n' = 0 to 255 specifies the threshold value for a random number attempt to transmit. 'n' = 0 Signifies a 1/256th chance of transmitting erery SLOTTIME. 'n' = 255 Signifies 'transmit right away without delay' When PK232 has data ready for transmission, the PK232 watches the DCD signal from it's internal modem. The PK232 waits forever for the DCD signal to go to the inactive state. When DCD goes inactive, meaning that the channel is clear, the PK232 generates a random number between 0 and 255. If the random number is equal to or less than PERSIST, PK232 keys the PTT line, waits .01 * TXDELAY seconds, and then transmits all frames in it's queue. If the random number generated is greater than PERSIST, the PK232 waits .01 * SLOTTIME seconds and repeats the procedure. If DCD has gone active in the meantime, the PK232 again waits for DCD to go inactive before it continues. PPERSIST (ON/OFF) DEFAULT: OFF ON - PK232 uses the PERSIST and SLOTTIME parameters in executing p-persistent CSMA (Carrier Sense Multiple Access). OFF - PK232 uses DWAIT for TAPR-type 1-persistent CSMA. RELINK (ON/OFF) DEFAULT: OFF ON - PK232 will automatically try to reconnect the distant station after the link has timed out on retries. OFF - PK232 will not attempt to re-establish the failed link. Set RELINK to OFF when using the PK232 with host computer applications. RESPTIME 'n' DEFAULT: 10 (1000 ms) 'n' = 0 to 250 100 ms intervals. Adds a minimum delay before the PK232 sends acknowledgement packets. RETRY 'n' DEFAULT: 10 'n' = 0 to 15 specifies the maximum number of packet retrys. 'n' = 0 specifies an infinite number of retrys. FRACK specifies the time between retrys. SENDPAC 'n' DEFAULT: $0D <CTRL-M> 'n' = $00 to $7F ( 0 to 127 decimal) ASCII character code. Selects the character used to force a packet to be sent in converse mode. Use SENDPAC $0D with CR ON to send packets with <CR> included in the packet. If CAPTIME ON, set SENDPAC to a value not ordinarily used, (for example <CTRL-A> with CR OFF). This setting forces packets to be sent without extra <CR> characters in the text. SLOTTIME 'n' DEFAULT: 10 (100 seconds) 'n' = 0 to 250 specifies the time interval during which the PK232 waits between generating random numbers, to see if it can transmit. SQUELCH (ON/OFF) DEFAULT: OFF ON - PK232 responds to positive going squelch voltage. OFF - PK232 responds to negative going squelch voltage. PK232 normally senses audio mark and space tones from the receiver as an indication that the channel is busy. If there are voice signals on the channel, the PK232 may not accept them as an indication that the channel is busy, and double with them. In this case, the squelch voltage from the radio can be fed into the PK232 to provide a positive means of determining if the channel is busy or not. SQUELCH permits either polarity of radio squelch voltage to be used. TRANS Switches PK232 from command mode to TRANSPARENT mode. The current state of the radio link is not affected. TRANSPARENT mode is used to transfer binary or other non-text files. TRIES 'n' DEFAULT: 0 'n' = 0 to 15 specifies the current RETRY level on the selected input channel. TRIES retrieves (or forces) the count of tries on the data channel presently selected. TRIES <with no argument> returns the current number of tries if an outstanding unacknowledged frame exists. If no outstanding unacknowledged frame exists, PK232 returns the number of tries required to get an ACK for the previous frame. TRIES is used to gather statistics on a given path or channel. TRIES 'n' forces the tries counter to the entered value. (This method is not recommended to force a new count into the TRIES counter). TXDELAY 'n' DEFAULT: 30 (300 ms) 'n' = 0 to 120 ten millisecond intervals. Tells PK232 how long to wait before sending packet frame data after keying your transmitter's PTT line. TXFLOW (ON/OFF) DEFAULT: OFF ON - Software flow control for Pk232 can be activated in the Transparent mode. OFF - Software flow control for PK232 is disabled in Transparent mode. If TXFLOW is ON, the settings of XFLOW determine the type of flow control used in Transparent mode. If TXFLOW is OFF, PK232 uses only hardware flow control; all data sent to the terminal remains fully transparent. If TXFLOW and XFLOW are ON, PK232 uses the START and STOP characters (set by XON and XOFF) to control the input from the terminal. Unless TRFLOW is also on, only hardware flow control is available to the computer or terminal to control output from the PK232. If START and STOP characters are set to $00, hardware flow control is always selected, regardless of the setting of TXFLOW. UNPROTO call1 [via call2 [,call3....,call9]] DEFAULT:CQ Sets the digipeat and destination address fields of packets sent in the unconnected (unprotocol) mode. call1 - call sign to be placed in the TO address field. call2-9 - Optional digipeater call list ( up to 8 calls). Unconnected packets are sent as unsequenced I frames with the destination and digipeat fields taken from call1 through call9 options. USERS 'n' DEFAULT: 1 'n' = 0 to 10 specifies the number of active simultaneous connections that can be established with your pk232. USERS only affects the way INCOMING connect requests are handled. It does not affect the number of connections that you initiate. VHF (ON/OFF) DEFAULT: ON ON - Packet modem tones are shifted 1000 Hz. OFF - Packet tones are shifted 200 Hz. ON is for VHF Packet operation. OFF is for HF Packet operation. WHYNOT ON/OFF (DEFAULT OFF) ON - PK232 will generate a reason why a received packet was not displayed on the screen. OFF - This function is disabled. ----------- Reasons for Bad Packets ---------------- Bit Residue - Frame ended in the middle of a byte. Passall - Received packet frame had errors and PASSALL was set to off preventing the packet from being displayed. DCD Threshold - The Threshold control was set to far CCW. The DCD LED was off when the packet was received. MONITOR - The MONITOR value was set too low to receive this type of frame. MCON - MCON was set too low to receive this type of frame. MPROTO - MPROTO was set to OFF and the received packet was probably a NET/ROM or TCP/IP frame. MFROM/MTO - The frame was blocked by the setting of either MFROM or MTO commands. MBX - The call sign of the sending station does not match the callsign setting in the MBX command. MBX SEQUENCE - The packet frame has been received out of sequence indicating that it is probably a "retry". FRAME TOO LONG - Incoming packet frame is longer than 330 bytes. Probably a non-AX.25 frame. FRAME TOO SHORT - Incoming packet frame is shorter than 15 bytes. Only seen if PASSALL is set to ON. Probably a non-AX.25 frame. RX OVERRUN - Another HDLC byte was received before the previous one could be read from the HDLC chip (8530). XMITOK (ON/OFF) DEFAULT: ON ON - Transmit functions (PTT Line) are active. OFF - Transmit functions (PTT Line) are disabled. If XMITOK is OFF, the PTT line to the transmitter is disabled. All other pk232 functions remain the same. XMITOK is set to OFF when you want to monitor channel activity without ever transmitting. ---------------------------------------------------------------------------- PK232CMD.LST (PART 4 OF 4) ---------------------------------------------------------------------------- ========================= MORSE COMMANDS ============================== MORSE PK232 is switched into Morse code mode.

ADELAY is the time between the instant the PTT line is activated for xmit, and the instant when ARQ data actually begins to flow to the transmitter. ALIST Switches PK232 into ARQ listen mode. (Mode L). AMTOR Switches PK232 into ARQ standby/receive mode. Any FEC (Mode B) transmissions will be displayed. ARQ aaaa Starts a Mode A SELCAL to a distant station. aaaa = the distant station's selective calling code. ARQTMO 'n' DEFAULT: 60 'n' = 0 to 250 'n' = number of seconds to send an ARQ selcal before automatic transmitter shutdown. FEC Puts PK232 in AMTOR Mode B. Use this mode to send an AMTOR CQ. Include your SELCAL in your transmitted FEC message so that other stations can call you in Mode A (ARQ). MYALTCAL aaaa DEFAULT: Empty aaaa specifies an Alternate SELCAL code. aaaa can be any 4 alphabetical characters or numeric strings of either 4 or 5 characters. MYSELCAL aaaa DEFAULT: empty Specifies your selective calling code (SELCAL) SELCAL must be specified before you can use AMTOR mode. Rules for determining your SELCAL: Group Call Selcal --------------------------- 1 by 2 W1XX WWXX 1 by 3 W1XXX WXXX 2 by 1 AB1X AABX 2 by 2 AB1XX ABXX 2 by 3 KA1XXX KXXX MYIDENT aaaaaaa DEFAULT: empty aaaaaaa specifies the user's seven character SELCAL as described in CCIR Rec. 625.

ON - Mode B FEC signals are displayed while in AMTOR standby. OFF - Mode B FEC signals are not displayed. SELFEC aaaa DEFAULT: empty aaaa specifies a distant station's selective calling code (SELCAL). SELFEC starts a selective FEC (mode Bs) transmission to the specified distant station, when you enter that station's SELCAL code. SRXALL (ON/OFF) DEFAULT: OFF Permits the reception of selectively coded inverse FEC signals normally not available for decoding. ON - Receive all selective (SELFEC) transmissions.

TDM Selects TDM mode (Moore Code). Use SIGNAL to check that received signal is really TDM. If TDM is detected, type "OK". AMTOR STATUS LED's are as follows: STBY: Trying to establish bit phasing. PHASE: Bit phasing established, trying to synchronize on characters. OVER: Character synchronization established. TFC: Printable character received. IDLE: Idling signals received. RQ: Error character of $00 or $7F received. ERROR: Other bad character received. The PHASE LED stays lit if the signal is too weak to achieve synchronization. Use the "R" command to force manual sync. Repeated use of the "R" command causes the bit synchronization to move along by one bit for each "R" command. "L" forces letters shift as in Baudot mode.. "N" forces figsures shift as in baudot mode. TRACE ON displays these characters: | = NULL * = LTRS % = FIGS a = Alpha Idle b = Beta Idle r = Signal Repetition Some TDM Frequencies: 19,101.9 LSB 18,983.6 USB 14.956.7 USB TDM stations idle most of the time. You may have to monitor a TDM station for an hour or more before any data is received. ========================= FAXCIMILE COMMANDS ========================== ASPECT n DEFAULT: 2 Controls the aspect ratio (length to width) of a FAX image. n = 1 to 6 specifies the number of FAX scan lines that the PK232 prints out, for every 6 lines received. For most weather charts ASPECT 2 works well. To stretch the image down the page, use a higher setting for ASPECT such as 4. The Index Of Cooperation is an International measure of aspec ratio. The CCITT IOC is: IOC = (Vertical scan line density) * (horizontal width) / pi The IEEE ICO is: IOC = (Vertical scan line density) * (horizontal width) ASPECT CCITT IOC (Narrow) CCITT IOC (WIDE) --------------------------------------------------------------- 1 1100 1788 2 550 (Weather charts 576) 894 3 367 (Wirephotos 352) 596 (Weather charts 576) 4 275 (WEFAX Satellite 288) 447 5 220 358 (Wirephotos 352) 6 183 298 (WEFAX Satellite) In receive, ASPECT 2 causes the PK232 to sample 2 out of every 6 lines received. ASPECT 4 causes PK232 to sample 4 out of every 6 lines received. In transmit, ASPECT 2 causes PK232 to send every line 3 times. ASPECT 4 causes PK232 to send even lines twice and odd lines once. When sending from one PK232 to another, it's best to run the same aspect ratio on both pk232's. DISPLAY (F)ax Displays all FAX related parameters. FAX Switches PK232 into Facsimile mode. PK232 starts in FAX standby, waiting to detect sync pulses that start a frame. FAXNEG (ON/OFF) DEFAULT: OFF ON - The white and black senses are reversed. OFF - The white and black senses are normal. FAXNEG is not the same as RXREV. RXREV inverts the entire signal, including the sync pulses. FAXNEG keeps the sync pulses upright, but inverts the image data only. FSPEED 'n' DEFAULT: 2 (2 lines/second) 'n' = 0 to 4 selects the FAX horizontal scan rate, in lines per minute. FSPEED (Highest print density Usable) narrow carrage wide carrage 1 1 line/sec 60 lines/min 275 dpi 169 dpi 2 2 lines/sec 120 lines/min 138 dpi 85 dpi 3 3 lines/sec 180 lines/min 92 dpi 56 dpi 4 4 lines/sec 240 lines/min 69 dpi 42 dpi 0 1.5 lines/sec 90 lines/min 183 dpi 113 dpi GRAPHICS 'n' DEFAULT: 1 (960 dots) 'n' = 0 to 6 selects the FAX horizontal graphics dot density printed on the printer. (See dot density Tables on pages M14 and M15 in PK232 manual) JUSTIFY 'n' Moves FAX image closer to the edge of the paper. 'n' = 0 to 25 number of 1/2 inches that the FAX image is to be moved closer to the edge of the paper. If LEFTRITE is ON, JUSTIFY 1 will move the image 1/2 inch to the left. If LEFTRITE is OFF, JUSTIFY will move the image 'n' half inches to the right. If the PK232 is allowed to synchronize by itself, JUSTIFY should not be needed. LEFTRITE (ON/OFF) DEFAULT: ON ON - The signal is scanned from left to right. OFF - The signal is scanned from right to left. LEFTRITE reverses the horizontal scanning direction. LEFTRITE is useful for printing wirephotos. LOCK Tells the PK232 to start printing regardless of whether or not the facsimile sync pulses have been detected. LOCK is a manual start command for FAX. Sync pulses consist of of lines of 5% white and 95% black, with the beginning of the white pulse signifying the left edge of the following image. If you issue a LOCK command to start FAX printing, you will probably need to use JUSTIFY to properly allign the image. OPMODE FAX STBY RCVE PK232 is searching for sync pulses to start printing the next image. OPMODE FAX SYNC RCVE PK232 has detected the sync pulses, or synchronization has been forced with the LOCK command, and PK232 should be starting to print the next image. OPMODE FAX STBY SEND PK232 is idling or sending the 300 Hz motor start tone, before it sends the sync pulses, or that it is sending the 450 Hz stop tone. OPMODE FAX SYNC SEND PK232 is sending either sync pulses or image dots. If the computer has not yet sent the image data to the PK232, PK232 will transmit a white tone continuously. PRCON (ON/OFF) DEFAULT: OFF Tells the PK232 whether or not a parallel printer is connected via the special "Y" facsimile cable. ON - A paralle printer is connected to the PK232 via the special FAX "Y" cable. The mode led's are disabled, and may stay lit or flash randomly. OFF - There is no paralle printer connected, or it is not currently in use. The mode led's are enabled, and correctly show operating mode and status. PRFAX (ON/OFF) DEFAULT: ON ON - FAX bit graphics are sent to the parallel printer for immediate printing if PRCON is also ON. OFF - FAX bit graphics are sent to the terminal via the serial port, using the printer escape codes, as set by PRTYPE and GRAPHICS. PRFAX should be sent to on if a parallel printer is connected and in use for printing FAX pictures. If you wish to save the FAX graphics data to disk, set PRFAX OFF and make sure AWLEN is set to 8 to allow 8-bit data to be sent to the serial port. PRTYPE 'n' DEFAULT: 2 (Epson) 'n' = 0 to 255 specifies a code for the type of dot graphics sequences used by your printer. (See pg M-19 of PK232 manual for list of PRTYPE codes.) XMIT TRANSMITS FAX DATA Keys the radio PTT line and prepares the radio to receive outbound FAX data. PRFAX must be OFF, AWLEN must be 8, and PARITY must be 0. ========================= ASCII COMMANDS ============================== ABAUD 'n' DEFAULT: 110 Baud Specifies data rate from PK232 to radio. 'n' = Baud Rate (45, 50, 57, 100,110, 150, 200, 300, 400, 600, 1200, 2400, 4800, 9600) ASCII Switches PK232 into Ascii Rtty Mode. ======================= SIGNAL (SIAM) COMMANDS ======================= BITINV n DEFAULT: $00 MODE: Baudot RTTY n = $00 to $1F (0 to 31 decimal) specifies a number to be exclusive ORed with every received Baudot character. $00 = no bit imversion, print plain text. CCITT (ON/OFF) DEFAULT: ON MODE: Baudot RTTY ON - If code is 0, PK232 uses the CCITT ITA #2 code in Baudot. OFF - If code is 0, PK232 uses the U.S. Teleprinter code in Baudot. CCITT has been replaced with the CODE command, but is retained for compatibility reasons. OK Accepts a set of parameters found using the SIGNAL command. Changes (or can change) RXREV, RBAUD, ABAUD, and OPMODE to the values found in using the SIGNAL command. ======================= NAVTEX MODE ================================= NAVMSG all, none, Yes/No (letters) DEFAULT: All Determines which type of NAVTEX messages your PK232 will print. all - print all types of NAVTEX messages. none - PK232 prints no NAVTEX messages. Yes (list) - PK232 prints only those types of NAVTEX messages specified by "list". NO (list) - PK232 prints all NAVTEX messages EXCEPT those specified by "list". A. Navigational Warnings B. Meteorological Warnings (Storm Warnings). C. Ice Reports. D. Search and Rescue Information. E. Weather Forecasts. F. Pilot Service Messages. G. DECCA System Information. H. Loran-C System Information. I. OMEGA Systems Messages. J. SATNAV System Messages. K-Z Reserved for future use. (up to 13 letter types can be monitored or rejected, and letters can be seperated by spaces commas or TABS) Types A,B and D cannot be excluded, and will always be monitored. NAVMSG is cleared by %, & or OFF NAVSTN all, none, Yes/No (letters) DEFAULT: All NAVTEX stations are identified by the first letter in the preamble. NAVSTN allows ALL, NONE, or up to 13 letters representing NAVTEX transmitting stations to be monitored or rejected. Letters in the list can be seperated by spaces, commas or TABS. NAVSTN is cleared by %, &, or OFF as arguments. NAVTEX Switches PK232 into NAVTEX receive mode. NAVTEX stations are found on 518 Khz. NAVTEX is a special for of mode B FEC, that does not output data to the computer or printer until "ZCZC" and a preamble are received intact. The preamble consists of 2 letters and 2 numerals. The PK232 will print until the end-of-message indicator "NNNN" is received. The first 2 letters define the transmitting station and the message class respectively. The following 2 numerals form a serial number that is remembered by the PK232, when a message is copied intact. The PK232 remembers the preambles of the last 200 printed messages, and will not re-print a message with the same preamble with the following exceptions: Any message with the preamble 00 is considered an emergency message, and will always be printed. Any message with more than 1/8 of it's characters received in error will not be saved, so that it may be re-printed. To clear preamble memory, exit, then re-enter NAVTEX mode. NAVTEX mode uses the setting of DAYTIME to print the date/time in front of the preamble, if MSTAMP and or DAYSTAMP are ON. NAVTEX NOTES: Navtex is broadcast in Mode-B AMTOR (SITOR) on 518 khz. ======================== ASYNC PORT PARAMETERS ======================== SYNCING PC to PK232 If PK232 has batteries installed, and a TBAUD baud rate has already been set, the AUTObaud routine will never come up. You must match the TBAUD baud rate with the COM port UART baud rate to communicate with the PK232. If PK232 does NOT have batteries installed, upon power up, it will transmit "Please Type * For Autobaud Routine" (at 1200 baud- default). At this point, you must send ONLY a "*", with no <CR> to sync the Pk232 with your baud rate. (several *'s may be required). The PK232 defaults to 1200 baud when TBAUD has never been set, or at power on, with no batteries installed. --------------------------------------------------------------------- Connection for IBM PC Serial COM Port to PK232 PK232 IBM PC 2 <---------------- 2 PC Transmit Data 3 ----------------> 3 PK232 Transmit Data 4 <---------------- 4 RTS 5 ----------------> 5 CTS 20 <-------------- 20 DTR 8 ----------------> 8 DCD - 6 ----------------> 6 DSR | | \ Pull-Up Resistor / \ / | | | + 10 Volts ======================== SPECIAL CHARACTERS =========================== Hardware Handshake is enabled if XFLOW = OFF.
