Fax Operation
9-10 Modem 3600
Class 1 Result Code +FCERROR
If the modem detects any carrier or tone that differs from that specified
in a +FRM or +FRH command, it sends the +FCERROR result code
and returns to command state, allowing the DTE to attempt a recovery.
The numeric form of this response is +F4.
Fax Autoanswer +FAA=
The modem can be set up to automatically detect if a fax or data call is
being answered. The command +FAA=1 enables this function and
+FAA=0 disables it. This feature requires special support by the fax
software package.
DTE Autobaud for Fax Autoanswer *FR
Set the fax autoanswer feature to autobaud at 19.2 kbps or greater, if
desired.
Binary File Transfer
Some Class 1 software packages may provide an option for transferring
files between computers with fax modems, using a Binary File Transfer
(BFT) standard. Although the received file is not a fax image,
transmitting the file is similar to sending a fax. Since the modem allows
T.30 error correction mode (with HDLC framing up to 9600 bps), fax
mode can also be used for BFT if supported by the Class 1 software
package. The Binary File Transfer is an option in the fax software
package, not a separate mode of operation.
