If that is a real hardware modem, this will work.

# Configuring a real hardware pci modem
To configure a pci modem, open an x terminal and su - to the root account:
Code:
[phil@fancypiper phil]$ su -
Password: 
[root@fancypiper root]# cat /proc/pci
Look for your modem in the returned list. Look for something similar to mine:
Code:
  Bus  2, device   2, function  0:
    Communication controller: PCI device 151f:0000 (TOPIC SEMICONDUCTOR Corp) (rev 0).
      IRQ 5.
      I/O at 0xc400 [0xc407].
With this info, I use the setserial command:
Code:
[root@fancypiper root]# setserial /dev/ttyS0 irq 5 port 0xc400 uart 16550a
Then I test the modem with the internet connection wizard and it works. I edit /etc/rc.d/rc.local and enter the setserial command:
Code:
[root@fancypiper root]# pico -w /etc/rc.d/rc.local
My file for an example
Code:
#!/bin/sh
# Redhat /etc/rc.d/rc.local file
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
# configure modem
setserial /dev/ttyS0 irq 5 port 0xc400 uart 16550a
Now, it remains configured after a reboot.

This was the reply that I got :
Bus 0, device 31, function 6:
Modem: Intel Corp. 82801DB AC'97 Modem (rev 2).
IRQ 9.
I/O at 0x2400 [0x24ff].
I/O at 0x2000 [0x207f].

I noticed that there were 2 I/0 values, which do i use? I tried the first one and it crashed my system

I don't know as I don't use a winmodem. I have been posting a link that is supposed to help. Have you tried clicking on it?
