Default serial RS232 down

Hi to all and sorry for my bad english.

Last week i have configured hylafax with a serial RS232 modem. it work
good for one day, but the day after it don't work.

i have try with cu -l ttyS0 and the system freeze: "connect... ... ..."
then, i have try with another modem: egual result. after i have try with
no RS232 modem attach... egual.

then i have think to buy and install a new PCI RS232 but the system
(Linux CentOS 5) don't reply at ttyS1.

we have an idea to install the PCI-RS232 ?

tnks to all.

lspci to find the IO address and IRQ of the PCI serial port, and
setserial to assign those values to ttyS1.
