4.2.1.4 +FRS - Receive Silence
This command causes the modem to listen and report an OK result code when silence
has been detected on the line for the specified period of time. This command will
terminate when the required period of silence is detected or when the DTE sends the
modem another character other than XON or XOFF, which is discarded. In either event,
the OK result code is returned.
This command is aborted if any character is received from the DTE after receipt of the
command but before the time delay elapses. In this case, the modem discards the
aborting character and issues an OK result code.

<time> Decimal number from 0 (default) to 255 which specifies the length of time in
10-ms intervals to
delay before responding with the OK result code after detecting silence on the line.
