[hylafax-users] Modem hangs on receiving

[Salvatore brigaglia <opensourcecat@xxxxxxxxx>]

Hi guys

I'm try to set up a complete send/receive environment with HylaFax+ on
a xen dom0 openSUSE machine but while i can send faxes without any
problem, when receivin the modem hangs. config.ttyS0 and one of the
failed receives log follows.

I am really new to hylafax, but for what i'v read here and there i
know that is better to have a rt kernel to operate with a fax
environment. A xen enabled kernel is not really rt so this can be the
problem. But what i need to find out (something i can't really
understand) is if it is clearly a kernel problem or a modem problem.
Please have a look at the logs:
