flexfax: URGENT HELP PLEASE: Problem with receiving fax

[shui@pointsnorth.com]

Hi Folks,

I'm sorry for the long message but I desperately need help to solve this
problem.

I've got another error on received fax.  My receive works only with some
fax machines and I got the following error message when someone tried to
fax me from their machine:

Sep 24 14:19:54.32: [ 7609]: SESSION BEGIN 00000201 14032649466

Sep 24 14:20:34.17: [ 7609]: SESSION END

whereas with another fax machine, I got a different error message:

I am running hylafax4.0pl1 on Solaris 2.6 and my modem is US Robotics
Sportster 28800 fax modem with v.34 and v.32 bis.   My modem configuration
file looks like this:

#

#
# 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
Class2NRCmd:        AT+FNR=1,1,1,0 # setup status reporting

I am not a modem expert and have no idea what those commands mean.   Even
worse is that it works for some fax machines and not the other.   That is
driving me nut and I almost scratch all my hair out of my head.

Could someone please kindly help and share their experience with me?  I'm
in desperately need for help.

Thanks folks for your kind attention and patience!
