[hylafax-users] MODEM /dev/ttyS1 appears to be wedged on a linux Redhat 7.1 system

["sachin" <sachindra.nath@iba.com.sg>]

Hi Guys,
   I urgently need some help to counter this problem, I had been facing for
the last couple of weeks. I have been trying to do a fresh installation of
hylafax 4.1.3 (as well as, later 4.1.4) on a linux redhat 7.1 system, doing
a source build. I am using a Class 1 modem It is a US Robotics 56K FAX EXT
Rev. 11.13.14 ...
I have been continuously getting the message
MODEM /dev/ttyS1 appears to be wedged

On a closer look on the server's trace log, I see that there is a timeout
encountered after Hylafax sends a ATZ message to the device. Attached is the
tracelog.

Sometimes, this call succeeds, but the modem times out when Hylafax sends a
ATE0 message to it. Can someone point out the problem ?

ps: When I try to send these same messages through minicom, it works fine.
All the test commands given in hylafax manual to check the modem, appear to
work fine for me. Could anyone throw some light on this please ?
thanks in advance...
regards
Sachin
