Re: [hylafax-users] TR: Sending Errors with 4.2.5

 Hi !

Just to inform you that my problem il nearly solved !
For some other reason I've moved the machine to another room, configuring
the same telephone lines from the PABX. But physically the plug are others,
and all my problems disappeared. From about 20 % the errors dropped to about
3% !! Without changing anything to the configuration nor to the machine
itself. 

Anyway thanks for your help and congratulations to the development Team ;-)

[I  have had a problem for posting this reply]

Lee & Andrew, thanks for help.

I've stopped the internal modem to exclude Linuxant and Linmodems problems
-> to see if some problem disappear I am a little lost identifying where the
problems come that's why I gave all of them, in case you found a _big_
configuration error :-) This may explain the messy presentation, sorry

 From now I looked in the transmission logs and the main remote fax machine
that fail are :

Canon Laser Class 2060
Canon Laser Class 9000 series
Brother MFC-3100C/MFC-8600

I'm trying to get informations on the receivers fax, and I'll post the
errors one by one as requested.

It's very hard to generalize a solution for you this way because you're
presenting a list of different error descriptions (and each error can occur
for different reasons) and you're using a variety of different modems.  The
best thing that you can do would be to post a typical error log for each
situation and to work at it error-by-error.

This (FCS errors in V.21 HDLC) seems to be a common issue with
Linuxant/Conexant modems these days.  I would recommend turning to Linuxant
for a solution on this... especially if you can reproduce it. 

I can send you a patch to disable the usage of CRP at this point (since it
may be confusing the receiver) to see if that helps alleviate the
consequences of the FCS error... but the real problem here, I suspect, is
with the modem.

Thanks,

Lee.
