The fax modem support four operating modes: buffer (normal), MNP reliable, V.42 auto-reliable, and V.42
reliable. These four modes are selected by the \Nn command. They allow the DCE to communicate with remote
modems that may or may not support error correction and data compression. Speed buffering, which is used
for all operating modes, allows the DTE-to-modem data rate to be different from the modem-to-modem data
rate. This is accomplished by using transmitter and receiver buffers in the modem. Thus the DTE-to-modem
data rate can be set for 2400 bps when the modem-to-modem data rate is 300 bps without causing any data
errors. In all data modes, the DTE-to-modem data rate can be set for any valid speed between 300 bps to
115,200 bps (that is, the modem autobouds up to 115,200 bps). The modem-to-modem data rates can be set
to 300, 1200, 2400, 4800, 7200, 9600, 12,200, 14,400, 16,800, 19,200, 21,600, 24,000, 26,400, 28,800,
31,200, and 33,600 bps. Each operating mode is explained in more detail in the following tables.

Fax Class 1 AT Commands
The 56-kbps fax modem 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 CL-MD56XX-based modem to
communicated with Group 3 fax machines. In addition, these product provide fax identity and test commands.
This manual 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 Cirrus Logic Class 1 Fax Application Note shows several examples of how the 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.

+FMFR? Identifies modem manufacturer none - no
+FMI? Identifies modem manufacturer none - no
+FMM? Identifies product mode none - no
+FMR? Identifies product version none - no
+FREV? Identifies product version none - no
NOTE: To originate a call, answer, and hang up, use the ATD, ATA, and ATHn commands, respectively.
Fax 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
