Transmit Silence — +FTS=(Time)
The command
+FTS=(Time)
causes the modem to wait in silence for
the specified amount of time and then send the
OK
result code to the
DTE. The
(Time)
value is in 10 ms increments from 0 to 2.55
seconds. The modem aborts the command and sends an
OK
result code
if the DTE sends an additional character, which is discarded, during the
command execution. This command returns an
ERROR
result code if
issued while the modem is on hook.
Receive Silence — +FRS=(Time)
The command
+FRS=
causes the modem to listen for silence and report
back an OK result code when the line has been silent for the specified
amount of time. The

value is in 10 ms increments from 0 to
2.55 seconds.
The modem aborts the command and sends an

issued while the modem is on hook.
