<min_tx_rate> and <max_tx_rate>

Numeric values which specify the lowest
(<min_tx_rate>) and highest (<max_tx_rate>) rate at
which the modem may establish a transmit connection.
Non-zero values for this subparameter are decimal
encoded, in units of bit/s. The possible values for each
modulation are listed in Table 5-3.
Actual values will be limited to possible values
corresponding to the entered <carrier> and fall-back
<carrier> as determined during operation. (Default =
lowest (<min_tx_rate>) and highest (<max_tx_rate>)
rate supported by the selected carrier.).

Report Commands:

+MS?

Reports current rates

Response: +MS:<carrier>,<automode>,<min_tx_rate>,
<max_tx_rate>, <min_rx_rate>,<max_rx_rate>

Note:

The current active settings are reported under control of

the +MR parameter.

Example: +MS: K56, 1,300,33600,300,56000

For default values. This example allows maximum system
flexibility to determine optimal receive and transmit rates
during operation.

+MS=?

Reports supported range of parameter values:

Response: +MS: (< carrier> range),(<automode>
range),(<min_tx_rate> range), (<max_tx_rate> range),
(<min_rx_rate> range), (<max_rx_rate> range)

Example 1:
+MS:(B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,
K56,V90),(0,1),(300-33600),(300-33600),(300-56000),(300-
56000)

Example 2:
+MS:(B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,
V90,V92),(0,1),(300-33600),(300-33600),(300-56000),(300-
56000)

Result Code:

OK - Valid subparameter string
Otherwise ERROR
