Defined Values
<carrier> A string which specifies the preferred modem carrier to use in
originating or answering a connection. <carrier> values are
strings of up to eight characters, consisting only of numeric
digits and upper case letters. <carrier> values for ITU standard
modulations take the form: <letter><1-4 digits><other letters as
needed>. Defined values are listed in Table A-3.
<automode> A numeric value which enables or disables automatic
modulation negotiation (e.g., ITU-T V.32bis Annex A or V.8).
0 = Automode disabled.
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 A-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_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 3-3.
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.)
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: K56, 1,300,33600,300,56000
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 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)
