+MS Modulation Commands

This extended-format command selects the modulation and, optionally, enables or
disables automode, specifies the lowest and highest connection rates, selects u-Low or
A-Low codec type, and enables or disables robbed bit signaling generation (server
modem) or detection (client modem) using one to five subparameters. The command
format is:
+MS=<mod>
Notes:
1. For 14400 bps and lower speeds, the Nn command and S37 register can
alternatively be used, in which case the +MS subparameters will modified to
reflect the Nn and S37=x settings. Use of the Nn and S37=x commands is not
recommended but is provided for compatibility with existing communication
software. (S37 is not updated by the +MS command.)
2. Subparameters not entered (enter a comma only or <CR> to skip the last
subparameter) remain at their current values.
Reporting Selected Options
The modem can send a string of confirmation to the DTE consisting of selected options
using the following command:
+MS?
The response is:
+MS: <mod>,<automode>,<min_rate>,<max_rate>,<x_law>,
<rb_signaling>
For example,
+MS: 56,1,300,56000,0,0
Reporting Supported Options
The modem can send a string of information to the DTE consisting of supported options
using the following command:
+MS=?
