+MS=? Displays range of acceptable values for each
subparameter
<carrier> Specifies the preferred modulation to be used in
originating or answering a connection. The
<carrier> subparameter is an unquoted string
of characters. If the <carrier> parameter is
specified, the other subparameters will revert to
factory defaults. If <carrier> is omitted, any
unspecified parameters will keep their current
values (for example, AT+MS=,0 or
AT+MS=,,,2400).
Values accepted for <carrier> are the following:
B103 Bell 103 (300bps)
B212 Bell 212A (1200bps)
V21 ITU-T V.21 (300bps)
V22 ITU-T V.22 (1200bps)
V22B ITU-T V.22bis (2400bps)
V23C ITU-T V.23 with constant carrier (1200/75 or 75/
1200bps)
V32 ITU-T V.32 (4800 or 9600bps)
V32B ITU-T V.32bis (4800 - 19200bps)
V34 ITU-T V.34 (2400 - 33600bps)
K56 (default) Lucent/Rockwell K56flex (32000 - 56000bps)
<automode> Enables or disables negotiation of an alternative
<carrier> if the preferred modulation is not
available.
Values accepted for <automode> are the following:
0 Disabled. Modem will disconnect if it is unable to
negotiate a connection with the specified <carrier>.
1 Enabled (default). If the specified <carrier> is unavail-
able, modem will attempt to negotiate an alternative
carrier as appropriate.
