                  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.

                 In Async mode RTS is always ON and CTS is always on
                    (unless &K3 is set, in which case CTS toggles for
                     flow control and RTS is ignored).
&Sn     DSR Mode Select
         &S0 Always on (default & required for Serial PnP)
         &S1 Follows EIA specification (Active following carrier tone, and
          until carrier is lost.)

          at 2400 or 9600, set the modem with AT&F0, and set S18 between 1 and

                 that individual subscriber. STATEMENTs are used for calls from

               * 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,

                {Any values omitted remain at the current setting}.
        Example: +MS? responds with "74,1,14400,28800" for VFC ONLY mode.

                 V22bis, Bell 212, and Bell 103 (assuming B1 is set) the
                 user can enter just "+MS=11,,300, <CR>" however an input
                 of "+MS=11,1,300,28800 <CR>" would give the same result.

        <mod> specifies the PREFERRED modulation as per the list below.
                Note that numeric or verbose <mod> selections can be

                        and <minimum rate> range for which standard automode
                        procedures exist using V8 or V32 Annex A.
                        Exampe: Failed V34 connection attempts can automode
                        to VFC or lesser protocols, but a Bell 103 connection
                        attempt cannot automode to V23.

        <minimum rate> sets the lowest carrier rate that may be used.
                (Default 300 bps)

        <maximum rate> sets the maximum carrier rate that may be used.

        NOTES:  The current code doesn't discriminate between short (0.4
                second) and long (0.8 second) ring pulses.  So two of the
                Bellcore standard ring patterns (RING 3 & RING 4) will be
                reported as RING3 (If RING 3 detections is active).

                                    supporting both protocols.  When this
                                    mode is active the modem listens to the
                                    answer signal from the remote modem.  If
                                    both ANSam (V.34 support) and PNID (VFC)
                                    are heard, the Supra attempts VFC hand-
                                    shake.  The PNID tone is at a lower

                                    the ANSam tone to be heard clearly.  Such
                                    a condition would cause the Supra to
                                    attempt V.34 handshake due to not

         period the EQM (%Q) level must be "GOOD" before attempting to "fall

S191    EQM Automatic Rate Adaption Bias (0-255, Zero Bias 128, Default 128)
         This adjustment affects V32,V32B,VFC,& V34 operation.  The bias
         offset is summed with the EQM(%Q) reading to determine the carrier
         rate to select during initial TRAIN and RE-TRAINS (Rate Renegotiation
         (Fall Back/Forward) & %Q reading are NOT affected by the S191 setting)
        -Positive bias (values above 128) tends to DECREASE the initial carrier
                rate for a given connection.
        -Negative bias (values below 128) tends to INCREASE the initial carrier
                rate for a given connection.

        Higher symbol rates have a better signal to noise ratio on a
        given line than the lower rates.  But the higher rates require
        more bandwidth than the lower ones.  When making a connection
        the highest symbol rate that will run over the available
        bandwidth is used.

SCn=n   Telephone Signal Cadence Settings (Defaults change with country code)
         Each register "pair" holds the value for each setting.  To set a
         value, divide the setting by 256.  The integer value goes in the
         second (high byte) register, while the remainder (low byte) goes in
         the first.  (A setting of 516 for the Phase 1 Minimum BUSY ON Time
         period would convert to 2 with a of remainder 4, and could be set by
         sending AT SC0=4 SC1=2 to the modem.)  Settings are in 1/100ths of a
         second.  Entries are listed as follows Minimum ON Time (2 bytes),
         Maximum ON Time (2 bytes), Min. OFF Time (2 bytes), Max. OFF Time
         (2 bytes), Number of valid singal cycles to occur before the signal
         is accepted as valid (1 byte).  Some countries codes specify a two
         PHASE cadence pattern (On-Off in one pattern followed by a different
         On-Off pattern) for some singals, and in such cases, the "PHASE 2"
         entries would have NON-ZERO values (the US country code setting only
         supports single PHASE cadence patterns or patterns that just repeat
         the same On-Off pattern over and over.)
