Frm, Receive Data; Fth, Transmit Data With Hdlc Frame - Motorola G24 Guide Developer's Manual

Fax Class 1

+FRM, Receive Data

This command causes the G24 to receive data from the remote party using the modulation
specified in <MOD>.
When the G24 receives the +FRM command it immediately returns a CONNECT result code.
When the terminal receives the CONNECT from G24, it can start receiving the data stream using
the transparent data command decoding. (Refer to
When the G24 receives the +FRM command, it checks the line for a carrier. If the G24 detects a
carrier, it sends a CONNECT to the terminal, and starts receiving the fax page.
Upon data stream termination, the G24 sends the termination sequence to the terminal.
Afterwards, if the G24 detects a loss of carrier, it sends a "NO CARRIER", otherwise it sends
OK.
