AT FAX Commands Reference

+FCLASS?

Service Class Indication

This command causes the modem to display the current setting. The modem can operate either as a Class 0 data modem or a class 1 FAX modem.

Typical responses: +FCLASS?

if in

VoiceView† mode.

+FCLASS=? Service Class Capabilities

This command causes the modem to display the classes it supports. Typical responses:

+FCLASS = ? 0, 1, 8, 80

+FCLASS=n Service Class Selection

This command sets the modem for class n operation, where n is either a 0 or 1. Parameters: 0, 1, 8, 80

Default:0 Command options:

+FCLASS = 0 Select data mode. +FCLASS = 1 Select Facsimile Class 1. +FCLASS = 8 Select voice mode. +FLCASS = 80 Select VoiceView mode.

+FTS=<n>

Transmission Silence

This command causes the modem to stop transmitting data and pause for 10 * n ms. At the end of this period, the modem then responds OK. You can specify any number from 0 through 255 as the value of n; for example, a value of 5 specifies a period of 50 ms.

n = 0¾255 (10 ms intervals)

+FRS=<n>

Receive Silence

This command causes the modem to listen and wait for a 10 * n ms period of silence on the line. At the end of this period, the modem then responds OK. You can specify any number from 0 through 255 as the value of n; for example, a value of 5 specifies a period of 50 ms.

n = 0¾255 (10 ms intervals)
