[hylafax-users] HDLC Frame too short...

[Martin Hucht <macgoever@xxxxxx>]

Hi everyone!

I was asked by my Boss to evaluate Hylafax for my company, before purchasing
an 3500,- Euro Appliance. I have to say that nearly everthing worked out of
the box, but sending a fax :/. I set up Debian and installed Hylafax 4.4.3.
I'm using a single Modem (1456VQE Topic Chipset). For cabeling reasons I'm
using a NPort 5610 RS232-Device Server.
Everytime I send a Fax I get this:

Some googeling brought up this Mail:
http://www.hylafax.org/archive/2003-10/msg00127.php

I think I have the same problem as described there, but I don't know how to
solve it. My guess is that I have to change the values of the software-wait-
parameters in the default topic modem config:

Class1PPMWaitCmd:       "<delay\0727>"  # \072 == :  to avoid awk problem
Class1TCFWaitCmd:       "<delay\0727>"
Class1EOPWaitCmd:       "<delay\0729>"
Class1SwitchingCmd:     "<delay\0727>"  # assumption: +FRS not supported

Maybe the software wait is too long and that's why the initial bytes of the
HDLC frame are missed?

The Modem itself is able to talk to any faxmachine available. I testet it (I
hate to admit it...) with WindowsXP Faxprinter.

Thanks for any idea!

Martin
