1 Automode enabled. (Default.)
<min_rx_rate> and <max_rx_rate>
Numeric values which specify the lowest (<min_rx_rate>) and
highest (<max_rx_rate>) rate at which the modem may establish
a receive connection. May be used to condition distinct limits for
the receive direction as distinct from the transmit direction. Values
for this subparameter are decimal encoded, in units of bit/s. The
possible values for each modulation are listed in Table 3-1. Actual
values will be limited to possible values corresponding to the
entered <carrier> and fall-back <carrier> as determined during
operation. (Default = lowest (<min_rx_rate>) and highest
(<max_rx_rate>) rate supported by the selected carrier.)
<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 3-1. Actual values will be limited to
possible values corresponding to the entered <carrier> and
fallback <carrier> as determined during operation. (Default =
lowest (<min_tx_rate>) and highest (<max_tx_rate>) rate
supported by the selected carrier.)
Reporting Current or Selected Values
Command: +MS?
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:
V90,1,75,33600,75,56000
For default values. This example allows maximum system flexibility to determine
optimal receive and transmit rates during operation.
Reporting Supported Range of Parameter Values
Command: +MS=?
Response: +MS: (<carrier> range),(<automode> range),(<min_tx_rate>
range), (<max_tx_rate> range),(<min_rx_rate> range),
(<max_rx_rate> range)
Example: +MS: (B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,
V90),(0,1),(75-33600),(75-33600),(75-56000),(75-56000)
