Re: [hylafax-users] faxgetty hangs with Zyxel U90E

My setup is :

- RH 7.3
- HylaFax 4.1.7 (installed via RPM)
- two Zyxel U90E modems both configured as Class 2 modems
- the only modified parameter in config.ttyS0/S1 is
Class2RecvDataTrigger: "\022" (I can't receive faxes without this !)

In other words it strictly obeys only the 2388-B draft instead of both 2388-A and 2388-B.

I can receive faxes from different fax machines for some hours without
any problem then, suddently, during the receive phase faxgetty stops
logging data in the session logs , faxstat -s says that the modem is
receiving but the transmission never ends !

Transcription of sample log follows:

at this point the only way I have to go on is to kill faxgetty (i.e.
restart hylafax) then I can see a new line in the session log :

Dec 03 15:12:50.11: [18335]: CLOSE /dev/ttyS0

This looks a lot like the problem reported on:

http://groups.google.com/groups?dq=&hl=en&lr=&ie=UTF-8&threadm=fa.cc3kru9.ihm939%40ifi.uio.no&prev=/groups%3Fdq%3D%26num%3D25%26hl%3Den%26lr%3D%26ie%3DUTF-8%26group%3Dfa.hylafax%26start%3D50

Try setting ModemPageDoneTimeout to 60000. I can also send you the patch I later sent to Thorsten.

I've found some similar (but not identical) posts in the archives and
I've installed 4.1.7 over my old 4.1.5 trying to solve the problem but
nothing changed.

So this problem happens both with 4.1.7 and with 4.1.5 ?

I've tried to configure Zyxel as Class 1 but I can't send or receive
faxes succesfully :

Set Class1FrameOverhead to 2. I think that may solve your Class 1 problem here.

And same thing here.

It seems there are problems related to Training phase but I'm not a
fax communication expert....

It appears that the modem does not report the FCS bytes in received Class 1 HDLC frames. Setting Class1FrameOverhead should resolve this.

What's the best way to configure Zyxel U90E for Hylafax usage ???

Ultimately I'd say that fixing the chinks in Class 1 for you will work best in the long-run, but it may take a little bit of configuration effort on your part.
