Dear subscribers,

After changing the system of our combined mail-/fax-server from W2k to
Linux, receiving faxes sometimes fails. The box is based on SuSE 8.2 and
hylafax-4.1.5-190 is used. The modems are initialized by FaxGetty and
receive facsimiles works fine - at least most times ;-)


During the last days the following error occured: An inbound call was
received, but after logging "MODEM set XON/XOFF/DRAIN: input
interpreted, output disabled" nothing happened. For several hours
'faxstat' looked like this:

mail:~ # faxstat
HylaFAX scheduler on mail.tett.de: Running
Modem ttyS0 (+49 2202 957229): Running and idle
Modem ttyS1 (+49 2202 246754): Receiving from "+49 6432 xxxxxxx"

Only killing the job by 'kill -SIGKILL pid' lead ttyS1 to idle state
again, 'faxabort' didn't work at all.

mail:~ # faxstat
HylaFAX scheduler on mail.tett.de: Running
Modem ttyS0 (+49 2202 957229): Running and idle
Modem ttyS1 (+49 2202 246754): Running and idle

The facsimililes have been sent be different machines, and the problem
occured on both modems. No further devices make usage of the serial
ports.


Strolling through mailinglists and google.de returned this result, but
unfortunately the problem keeps unsolved:
