Appendix A AT Commands
61
Note: This command controls automatic switching from class 1 to class 0 for
call answering only. It does not affect call origination, switching to class 1
from other classes, or switching to classes other than class 0.
+FAA=0 The DCE will answer only as a class 1 FAX device. No
automatic switching of service class will occur based on the
calling device type (default).
+FAA=1 The DCE can answer and automatically determine whether to
answer as a facsimile DCE or as a data modem.
+FCLASS=1—Enter Class 1 FAX Mode
The +FCLASS=1 command puts the modem in class 1 FAX mode.
+FMI?—Manufacturer Identification
This command returns: Agere Systems
+FMM?—Product Identification
This command returns the result: Data/FAX.
+FMR?—Version/Revision Information
This command returns the modem version code.
+FPR=<value>—Select FAX Port Rate
This command sets the DTE to DCE FAX port rate. The +FPR command is
supported to assure compatibility with communications software that issues
the this command. Soft modem products do not maintain the traditional
relationship between the DTE and DCE that this command was designed to
control. Soft modem products interface with the host system via a PCI or
AC97 interface.
+FRH=<mod>—Receive HDLC Data with <mod> Carrier
Use the +FRH command to instruct the modem to receive data framed in the
HDLC protocol at the modulation defined as below:
Command Modulation Speed
+FRH=3 V.21 channel 2. 300 bits/s.
+FRH=24 V.27ter. 2400 bits/s.
+FRH=48 V.27ter. 4800 bits/s.
+FRH=72 V.29. 7200 bits/s.
