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 cur-
rent setting and the range of services available. This is provided by the
command.
Service Classes supported by the ME:
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.
