Fax Class 1 AT Commands

Fax Class 1 AT Commands

5

The 536EX chipsets implement 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 536EX-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 22; all other fax AT commands are provided in Table 24 on page 67.

5.1Fax 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.

Identifies Modem Manufacturer: This command causes the DCE to send a message to the DTE

 

 

indicating the DCE manufacturer. This command is identical to ATI2 and AT+GMI.

OK

 

 

 

 

 

Identifies Product Model: This command causes the DCE to report the modem chipset name.

 

 

This command is identical to ATI1 and AT+GMM.

+FMDL?/+FMM

none

OK

 

 

 

 

 

Identifies Product Version Number: This command causes the DCE to report the modem

 

 

chipset revision level. This command is identical to ATI4 and AT+GMR.

+FREV?/+FMR

none

AT+FREV?

5.2Fax Class 1 Commands

The fax Class 1 AT commands are divided into three types: class selection and capabilities, data stream transfers, and silence-time timers. All fax mode commands, except the silence-time timers, must be the last command on the command line.

Each command may be used as follows:

+F<command>?

Reads current setting

+F<command> = ?

Reads permissible settings

+F<command> = <parameter>

Sets parameters

Note: To originate a call, answer, and hang up, use the ATD, ATA, and ATHn commands, respectively.
