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 (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.

Fax Transmit and Receive Modes

facsimile data with the designated modulation. Flow control, data buff-

ering, and data filtering are used as appropriate, in accordance with the
