[hylafax-users] Receiving corrupted faxes.

[APS <dev.malst@xxxxxxxxxxxx>]

Hi,
 
I?m looking for support on the following problem.
I have an instance of Hylafax (v. 4.4.4 ) running on linux (debian v.
5.0.4) with 8 modems, some of them connected via serial port, some
through a serial to usb adapter.
All modems are Digicom (model BOTTICELLI WEB CX

http://www.digicom.it/digisit/prodotti.nsf/ITProdottiIDX/BotticelliWebCx?OpenDocument
) 
 
Hylafax is used only as a receiver.
The daily average load is about 100 fax (300 pages) received.
 
About 75%-80% of the documents are received without problems, but on the
remaining part I have seen the following behaviors:
-        Fax receiving aborted (log
included at the end of the message)
-        Documents without pages or
with pages made only of 5-10 lines (not understandable at all)
-        Pages missing several lines
or with lines replaced by black line or inconsistent data
 
The following is the log of an aborted transmission and the configuration
of the related modem.
 
Thanks in advance to anyone who will contribute.
