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.
