TITLE   : Fax Class Capabilities of a Fax Modem
PRODUCT : Procomm Plus 4.x, 3.x
==============================================================================

This document details how you can determine the fax class capabilities of your
fax modem.

QUERY THE MODEM
From the Procomm Plus Terminal screen, type AT+FCLASS=? and press <Enter>.  If
your modem does not support any faxing capabilities, an "ERROR" message will
be returned to the Terminal window. If your modem supports fax, it will
respond with one or more numbers separated by commas. In addition, some modems
also respond with a "+FCLASS=" prefix before the numerals. For example, "0,1",
"0,1,2" and "+FCLASS=0,1" are valid responses.

The numeric responses represent the capabilities of the fax modem, where

    0 = data mode

    1 = Fax Class 1

    2 = Fax Class 2

    2.0 = Fax Class 2.0

Fax class 1 and 2 are supported by Procomm Plus, but fax class 2.0 is a newer
specification which is not supported.  Procom Plus also supports another fax
class called Sendfax.  Your fax modem may also support other fax
classifications which, like Sendfax, are not identified by the "AT+FCLASS=?"
query.  These can only be identified by the fax modem's documentation.
