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.
