> 12. | FAX Commands

> This chapter describes the AT commands used for fax communications. Please note that fax related commands are not supported by Java.
> 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 current setting and the range of services available. This is provided by the AT+FCLASS command.
> Service Classes supported by the ME:

> AT+FCLASS Parameter | Service class | Reference, Standard
> 0 | Data modem | e.g. TIA/EIA-602 or ITU V.250
> 1 | Service Class 1 | EIA/TIA-578-A

> During an active fax connection the AT parser functionality on the used channel is limited to the AT commands which according to the ITU V.250 and T.31 specifications are mandatory for fax communications. The functions of these AT commands are usually supported by commonly used fax applications.
