flexfax: "unable to setup modem on /dev/cua2" problems

[Mark Buckaway <mark@datasoft.on.ca>]

The system:
Pentium 166, GVC 33.6 modem (that all ATI commands report as a USR), Redhat
Linux 5.0

The situation:
Outgoing faxes work just find. I can send faxes to my heart's content. But, for
the life of my, I cannot setup faxgetty for incoming faxes. It constantly
reports it's Unable to setup the modem. I think this is a problem with what my
modem reports for the class query, but, it works for outgoing. Basically, after
sending the AT+FCLASS=? command, the modem returns the 0,1,2.0 response, OK and
then faxgetty thinks something failed and says:

/dev/cua2: Can not initialize modem.

I'm stumpped. I've read the docs, the FAQ's, and can't seem to figure this one
out. No doubt it's something simple I am missing.

Help.

Below is a session from faxgetty as well as my config for the modem.

This is basically the usr-2.0 config since the modem reports itself as a USR
Sportster 33.6 modem even bought I got in a GVC box.

ModemType:              Class2.0        # use class 2.0 interface
ModemRate:              38400           # DCE-DTE communication rate
ModemFlowControl:       rtscts          # XON/XOFF flow control assumed

ModemNoFlowCmd:         AT&H0&I0&R1     # setup modem for no flow control

#
ModemSetupDTRCmd:       ATS13=1&D2      # setup so DTR drop resets modem
ModemSetupDCDCmd:       AT&C1           # setup so DCD reflects carrier (or not)
ModemResultCodesCmd:    ATQ0X4          # enable extended result codes

#
#ModemSetupAACmd:       AT+FAA=1
#
# Set modem speaker volume commands: OFF QUIET LOW MEDIUM HIGH.
# Note that we both turn the speaker on/off and set volume.
#
ModemSetVolumeCmd:      "ATM0 ATM1L0 ATM1L1 ATM1 ATM1"
#
# Modem does not support HDLC frame tracing; we add this just
# to eliminate spurious ERROR results that confuse the naive.
#
Class2BUGCmd:           AT+FBU=0
#
# The modem doesn't support copy quality checking, even though it
# returns (0-2,0-2) for AT+FCQ=?; therefore we override the query
# response so that the server will do copy quality checking.
#
Class2CQQueryCmd:       !(0),(0)        # override modem response
