13.3 V.92 Commands
Command: +MS= Modulation Selection
Values: See description.
Defaults: See description.
Description This extended-format command selects modulation, enables or disables automode,
and specifies the highest downstream and upstream connection rates using one to
four subparameters.
The command syntax is
+MS=[mod][,[automode][,[0][,[max_rate][,[0][,[max_rx_rate]]]]]]<CR>
Subparameters that are not entered retain their current value. Commas separate
optional subparameters, and must be inserted to skip a subparameter. Example:
+MS=,0<CR> disables automode and keeps all other settings at their current
values.
+MS=?
Reports supported options in the format (list of supported mod values),(list of
supported automode values),(0),(list of supported max_rate values),(0),(list of
supported max_rx_rate values). Example: +MS: (BELL103, V21, BELL212A, V22,
V22B, V23C, V32, V32B, V34, V90, V92), (0, 1), (0), (0-33600), (0), (0-56000)
+MS?
Reports current options in the format mod, automode, 0, max_rate, 0, max_rx_rate.
Example: +MS: V92, 1, 0, 31200, 0, 56000.
Subparameters
mod
Specifies the preferred modulation (automode enabled) or the modulation to use in
originating or answering a connection (automode disabled). The default is V92.

Notes: 1. See optional < automode >, < max_rate >, and < max_RX_rate > subparameters. 2.
Selects V.92 modulation as first priority. If a V.92 connection cannot be established, the modem
attempts V.90, V.34, V.32bis, etc. 3. Selects V.90 modulation as first priority. If a V.90
connection cannot be established, the modem attempts V.34, V.32bis, etc.
automode
An optional numeric value that enables or disables automatic modulation negotiation using V.8 bis/V.8 or
V.32 bis Annex A. Automode is disabled if values are specified for the max_rate and max_rx_rate
parameters. The options are:
