12. FAX Commands

This chapter describes the AT commands used for fax communications.

If the ME is acting as a fax modem for a PC based fax application (e.g. "WinFax") it is necessary to select the

proper Service Class (Fax Class) provided by the ME. The ME reports its Service Class capabilities, i.e. the cur-

rent setting and the range of services available. This is provided by the AT+FCLASS command.

Service Classes supported by the ME:

The following AT commands are dummy commands:

AT+FAA Auto Answer mode

AT+FECM Error Correction Mode control

AT+FLNFC Page Length format conversion

AT+FLPL Indicate document available for polling

AT+FMINSP Minimum Phase C speed

AT+FRBC Phase C data receive byte count

AT+FREL Phase C received EOL alignment

AT+FSPL Enable polling

AT+FTBC Phase C data transmit byte count

AT+FWDFC Page width format conversion

Invoking these commands will not cause ERROR result codes, but these commands have no functionality.

Below you can find a summary of parameters used by the fax-specific AT commands and responses described

in this chapter. Please note that parameter <mod> is dedicated to Fax Class 1 only. All other parameters listed

below are for Fax Class 2 only.
