Syntax:
<carrier> Values:
ATMS=<carrier>,<automode>,<min_rate>,<max_rate>,<min_rx_rate>,
<max_rx_rate>
V92 V.92 (default)
V90 V.90
V34 V.34
V32B V.32bis
V32 V.32
V22B V.22bis
V.22 V.22
Bell212A Bell 212A*
V23C V.23, constant carrier, asymmetric FDM
V21 V21
Bell103 Bell 103*
*The +MS command was standardized by ITU-T recommendation V.250. However,
the standard command does not include the additional functionality provided by the
Bell212A and Bell103 values of the <carrier> parameter.
<automode> Values:
<max rate> Values:
Automatic modulation negotiation is enabled or disabled by <automode>.
However, if a value is specified for the <max_rate> then, automatic rate selection
is disabled and the modem will attempt to connect at the specified rate.
0 Disables automode.
1 Enables automode. (Default)
The <max_rate> specifies the highest connections rate for the DCE.
31200
Determined by modulation selected in <carrier>. (Default)
300-56000 Value limited by modulation selected <carrier>.
<max rate> for each <carrier>.
V34
2400 bits/s—33600 bits/s in steps of 2400 bits/s.
V32bis 4800 bits/s—19200 bits/s in steps of 2400 bits/s.
V32
4800 bits/s—14400 bits/s in steps of 2400 bits/s.
V22bis 2400 bits/s.
V22 2200 bits/s.
V23C, Bell212A 1200 bits/s.
V.21, Bell103 300 bits/s.
Valid <max rate> Range
56000
Determined by modulation selected in <carrier>. (Default)
