[hylafax-users] Patton 2977 timeout in class 1

["Christian M. Watts" <cmwatts@xxxxxxxxxxxxx>]

Hi,

I'm having an issue with the following configuration:

Gentoo Linux - kernel 2.4.30
Patton 2977 (AKA Digi Datafire RAS) - latest firmware from Patton support
Hylafax 4.2.5

What I'm seeing is that for sending to some destinations (where 'some' is around
2-3% of destinations I send to) I'm getting a timeout when receiving the initial
HDLC frame after connect. This only applies when running the modem in Class 1.
Class 2.0 seems to resolve this particular issue, but introduces other problems
on the receiving side, so I'd rather be running in Class 1 if possible.

An example session log and my config are below (number's X'd out to protect the
innocent). If anyone has any suggestions, I would appreciate them. I have tried
increasing FaxT4Timer with no effect and have also tried specifying
Class1ResponseWaitCmd and Class1TCFWaitCmd as AT+FRS=5 with no effect on the
issue.

Thanks,
Christian

Class 1 Modem Config:

# $Id: digi,v 1.3 2005/02/01 21:57:38 lhoward Exp $
#
# prototype config for Digi AccelePort RAS
# It uses a K56 chip, but is similar in behavior to Lucents.
#
# Note that because the devices are named as "ttyG0_00" (which on some
# systems indicates a subdirectory, i.e. "ttyG0/00") you must:
# `ln -s /dev/ttyG0_00 /dev/ttyG000`
# for each device and refer to the symlink.  Otherwise various HylaFAX
# functions will fail.
