4 AT Commands, S-Registers, and Result Codes
+MS=? Reports supported options in the format: +MS: (list of sup-
ported <mod> values), (list of supported <automode>
values),(list of supported <min_rate> values),(list of supported
<max_rate> values), (list of supported <x_law> values), (list of
supported <rb_signaling> values)
Example: +MS: (0,1,2,3,9,10,11,56, 64,69),(0,1),(300-33600),(300-
56000),(0,1),(0,1)
Subparameters
<mod> A decimal number that specifies the preferred modu-
lation (automode enabled) or the modulation to use in origi-
nating or answering a connection (automode disabled). See
the following table:
<mod> Modulation
0 V.21
1 V.22
2 V.22bis
3 V.23
9 V.32
10 V.32bis
11 V.34
2
12 V.90
3
56 K56flex
64 Bell 103
69 Bell212
Notes:
1. See optional <automode>, <min_rate>, and <max_rate> subparameters.
2. Selects V.90 modulation as first priority. If a V.90 connection cannot be established,
the modem attempts K56flex, V.34, V.32bis, etc.
3. Selects K56flex modulation as first priority. If a K56flex connection cannot be
established, the modem attempts V.90, V.34, V.32bis, etc. (Default.)
<automode> An optional numeric value that enables or dis-
ables automatic modulation negotiation using V.8 bis/V.8 or
V.32 bis Annex A. The options are:
0 = Disable automode
1 = Enable automode (default)
<min_rate> An optional number that specifies the lowest rate
at which the modem may establish a connection. The value is
decimal coded in units of bps, e.g., 2400 specifies the lowest
rate to be 2400 bps. See "Possible rates" in the <mod> table.
The default is 300 for 300 bps.
<max_rate> An optional number that specifies the highest
rate at which the modem may establish a connection. The
value is decimal coded, in units of bps, e.g., 14400 specifies the
1
