+MS – Select Modulation
Supported by: TDW-33 TD-36 TD-36 485 TR-36
Description:
This command selects the modulation, enables or disables automode, specifies the
receive rates and specifies the transmit rates using six subparameters.
Syntax:
+MS = <carrier>,<automode>,<min_tx_rate>,<max_tx_rate>,<min_rx_rate>,<max_rx_
rate>
+MS = ?
+MS ?
