5. 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.

5.1 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.

Table 5-1. Fax Identity Command Descriptions

Command	Default	Description
		Identifies Modem Manufacturer: This command causes the DCE to send a
		message to the DTE indicating the DCE manufacturer. This command is identi-
		cal to AT+GMI?.
+FMFR?/+FMI?	none	AT+FMFR?
		Intel Corporation
		OK
		Note: The DTE manufacturer name can be changed with the firmware
		configuration utility.
		Identifies Product Model: This command causes the DCE to report the mo-
		dem chipset name. This command is identical to ATI3 and AT+GMM?.
		AT+FMDL?
+FMDL?/+FMM?	none	MD56xx
		OK
		The modem responds with ‘MD566X’ for all chipsets that support V.42/MNP pro-
		tocols.
