flexfax: Modem fax´es thin strokes frequently

[Ekkard Gerlach <SPS_Gerlach@online.de>]

platform Linux (Suse 6.1), hylafax, faxgetty
============================================



Hello,

my external modem ("Arowana", 57,6 , 1/2 year old, 
Texas Instruments-chipset) faxes 
frequently thin strokes in confused order 
in then second part of some of my fax´es
thant I send.

Who can help?

Thanks in advance, Ekkard



Further data :

1. using Linux, Hylafax, faxgetty

2. The thin strokes that appear on serveral 
receiving stations. The fault is with the 
sending station (my modem).  The fault happens
with 9600 baud or with 14400 baud (tested with 
an old 9600baud-receiving station and with an 
newer one with 14400)

3. The thin strokes are dependant of the format of 
the fax. The errors I have detected so far always
occured with letters with standard letter format:
sender, receiver, place & Date on the top. 
When I delete the sender and receiver on my letter
the fax was sended without error (=fine strokes) !!!!

4. I can send the fax for serveral times. The error
occurs each time. The error is 100% reproduceable.

5. faxgetty doesn´t detect any fault. In 
/var/log/messages   there appears "... done ..."
as if all would be all right.

# We normally append the "@" symbol to the dial string so that

# repeatedly dialing a number that doesn't have a fax machine
# (kudos to Stuart Lynne for this trick.)
