&C - RLSD Behavior
This parameter determines how the state of the Received Line Signal Detector (RLSD) output
relates to the detection of received line signal from the distant end. Changing the parameter
will take effect immediately in both the command and online command states.
In &C1 mode of operation, RLSD is not turned off until all data previously received from the
remote modem is delivered to the local DTE. However, such buffered data will be discarded
and RLSD will be turned off if the DTE turns off DTR (if &D1 or &D2 is set).
Syntax

Defined Values
<value> Decimal number corresponding to the selected option.
0 RLSD is always ON.
1 RLSD follows the state of the carrier. (Default.)
Result Code
OK <value> = 0 or 1
ERROR Otherwise.
