[hylafax-users] Troubles with external USRobotics

[Héctor Sánchez Sanmartín <hector@xxxxxxxxxxx>]

Dear all,

I've got Hylafax v4.3.4 installed on a CentOS 4.3, configured with one 
3Com USRobotics 56K external modem (connected via the serial port) as 
sending/receiving fax server.
Normally it operates fine but sometimes after reporting a failure in fax 
receiving, the modem hangs (hylafax starts sending the "modem on 
/dev/ttyS0 appears wedged") without any chance to recover it. If  I try 
to communicate to the modem (using minicom or wvdialconf) it reports 
there is no modem.
I reseted the modem (taking the power off and on) but it continues 
hanging. I even reseted the whole server and still the same. The only 
way I found to make the modem work again (a dirty one) is to poweroff 
the server, boot it without the modem attached to the serial port (kudzu 
removes it the config), poweroff the server again, connect the modem to 
the serial port, boot the server once more (kudzu detects and configures 
it) and everything works again.
The problem is that I cannot reproduce the problem, it only happens from 
time to time (not very often) but its very annoying as I need to reboot 
the server. I changed the modem to a new one and today it happened 
again. I suspect the problem comes from the modem, but I'm not sure that 
it could come to a misconfiguration. Let me know if you want me to send 
any config file or log.

Does someone had the same trouble with a USRobotics modem? I would like 
to try changing the modem to see if the problem disappear, any 
suggestion about a modem which is proven to work perfectly with hylafax?

Any clue you could provide to solve this touble would be more than welcome!

Thanks a lot in advance
