FAX CLASS 1 AT COMMANDS

The 56K FastPath family implements the EIA-578 data/fax Class 1 AT command set standard. This
AT command set allows a DTE (with Class 1 communication software) and a MD566X–based
modem to communicate with Group 3 fax machines. In addition, these chipsets provide fax identity
and test commands. Fax identity commands are described in

Table 5-1

; all other fax AT commands

are provided in

Table 5-3 on page 76

. This programmer’s guide should be used with the Class 1

Fax Application Note and the specifications for EIA/TIA-578, ITU-T T.30, and T.4. The Intel
Class 1 Fax Application Note shows several examples of how to use the fax AT commands and
how to originate and answer a fax call.

Fax Identity Commands

The fax identity commands are AT+FMFR?, AT+FMDL?, AT+FMI?, AT+FMM?, AT+FMR?,
and AT+FREV?. These commands respond back with modem manufacturer, product model, and
product revision information.
