each time i try to query my modem using KPPP and specifying my modem device as /dev/ttyS0 - /dev/ttyS3 it says "Modem Busy"

Im using an internal modem from Agere Systems

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

Okay..so what do i do next to configure it to work?

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?
