Fax Origination
Origination of fax calls is made using the ATD command. Upon completion of the
dial function, a calling tone at 1100 Hz is transmitted, with a cadence of 0.5
seconds on and 3 seconds off. The modem automatically enters mode +FRH=3
and sends the CONNECT message to the DTE when FSK flags are detected from
the remote.
