Full AT Command Set Listing for the SupraFAXModem Series NOTE: This file includes commands, result codes, and display codes NOT AVAILABLE on all models and revisions. Some commands are new or were omitted from Reference Manual. NOT ALL commands are available or functional in all modes and states. This document is provided for reference only and is NOT certified to be free from errors. This document is produced and maintained by Supra's Technical Support Staff as a customer service. AT_LIST.TXT Rev 2.9 (PHM 7/20/93) from Supra BBS (503)967-2444 The command string buffer on the SupraFAXModem is limitted to 254 charactors. DIRECT Commands (Commands NOT preceded by other charactors) A/ Re-execute Last Command nnn Escape Code per setting in register S2 (Default is ANSI charactor 43, the "+" symbol) (This command must be proceded and followed by a minimum period of no transmission set is register S12.) (A carriage return) - Terminate connection attempt in progress during the dialing or protocol neg. process. DIALING Commands (Commands that follow ATD) -()i These symbols and spaces are ignored (or invalid and therefore ignored) and maybe be used in the dialing string. 0-9 DTMF code for the given number A-D DTMF code for the given letter J Do MNP 10 link negotiation at highest rate (this call only, see *H) K Enable power level adj. during MNP 10 link neg. (this call only, see Mn) L Dial the last dialing string (limitted to the first 40 charactors). P Pulse dial the following digits R Reverse Carrier Mode (Dial with ANSWER rather than ORIGINATE carrier.) (Some models accept, but do not support, this command.) Normal Mode: Calling Side: ATDTn Answering Side: ATA Reverse Mode: Calling Side: ATDTnR Answering Side: ATXD Sn Use dialing string stored in register n (0 to 3) T Tone dial the following digits W Wait for dialtone * DTMF code for "star" # DTMF code for "gate" @ Wait for "quiet answer" (A 5 second silence.) , Pause (time set in S8) before finishing dialing string !

Be VERY careful when issuing these commands! Once you enter &Q(1-3) and save it to memory, there are only three known ways to return to Asynchronous Mode: 1. Issue AT &Q(0,5-9) &W from a Synhronous Terminal to restore the modem to Asynchronous Mode. 2. Connect modem to an Asynchronous Terminal with the DTR signal (line 20) disabled (a "break-out" box works very nicely for this) and issue the configuration you want or AT &Q(0,5-9) &W to return the modem to Asynchronous Mode. 3. Send the modem in to our repair department. &Q4 Not Used &Q5 Asynchronous Reliable Mode (most common default) &Q6 Asynchronous Normal Mode &Q7 Not used &Q8 Asynchronous Reliable Mode w/o v.42/v.42bis &Q9 Asynchronous Reliable Mode w/o MNP 2-5 &Rn RTS Synchronous Mode (In Asynchronous mode CTS is always ON unless &K3 is set.) &R0 CTS responds to RTS (default) &R1 CTS always on unless &K3 is set &Sn DSR Action Select &S0 Always on (default) &S1 Follows EIA specification (Active following carrier tone, and until carrier is lost.) &Tn Modem test modes for trained technicians (you must set the serial port at 2400 or 9600, set the modem with AT&F0, and set S18 between 1 and 255if you wish the tests to stop on their own.)

The integer goes in the second register, while the remained goes in the first. (A setting of 516 would convert to 2 Remainder 4, and could be set by sending ATSC0=4SC1=2 to the modem.)
