When DTR is dropped modem returns to Async. &Q2 * Synchronous Mode 2 Modem dials number in stored location 0 when DTR goes from LOW to HIGH. &Q3 * Synchronous Mode 3 Dial number manually on a telephone, and then bring DTR high to let the modems connect. * CAUTION! 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 Synchronous 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.)

STATEMENTs are used for calls from non Caller ID Areas and subscribers requesting no display. NAME= listed subscriber name "Multiple Page Mode" MESG= formatted number string * ** * Here is an example string: 030A35303339363732343030 The string uses this code: CCLL#0#1#2#3#4#5#6#7#8#9 CC (03) is the code meaning this is "Multiple Page" Caller ID LL is the hexadecimal length of the data in the string. (in this case 0A hex - 10 decimal) #n's are the ASCII digits dialed (in hexadecimal) A neat trick to convert these to decimal is to note that the first digit is always a number "3" and the second digit is the decimal number dialed, so the formatted string: 030A35303339363732343030 converts directly to 5039672400 ** At the time of this printing, conversion of "Multiple Page" Caller ID string coversion is not supported in the modem, so the data is displayed in the raw hexadecimal format. #CID=2 Enable Raw (ASCII printable HEX number) Mode #CID=?

(If the modem steps back down, it will also follow the S109 settings.) SCn=n BUSY Detect Watermark Controls Each register "pair" holds the value for each setting. To set a value, divide the setting by 256. 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.) Settings are in 1/100ths of a second.

(Supra's staff cannot assist you in regard to these commands, and under no case should you attempt use or adjust these settings.): ATS91=x ATS92=x ATS99=x AT!(x) These commands are quite powerful and can cause unpredictable or total lack of operation. (In many cases, service at Supra would be required to restore normal operation.)
