AT Commands for CX81801/CX06833/CX81300/CX06827 Modems Reference Manual
102184B Conexant 3-59
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: V92, 1,300,48000,300,56000
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: +MS:(B103,B212,V21,V22,V22B,V23C,V32,V32B,V34,
V90,V92),(0,1),(300-33600),(300-48000),(300-56000),(300-56000)
Result Code
OK Valid subparameter string
ERROR Otherwise.
+MR - Modulation Reporting Control
This extended-format numeric parameter controls whether or not the extended-format
+MCR:<carrier> and +MRR:<rate> intermediate result codes are transmitted from the
modem to the DTE. If enabled, +MCR:<carrier> and +MRR:<rate> intermediate result
codes represent the current (negotiated or renegotiated) modulation <carrier> and <rate>
that are transmitted at the point during connect negotiation (handshaking) at which the
modem has determined which modulation and rate will be used, i.e., before any Error
Control or Data Compression reports are transmitted, and before any final result code
(e.g., CONNECT) is transmitted.
S95 bit 2 is reset to 0 for +MR=0 and is set to a 1 for +MR=1 or +MR=2. The more
recent setting of +MR or S95 bit 2, and the W command setting, determines modulation
result code reporting (see S95 Parameter and W Command).
