configuring my modem for dialup
Hey, i'm new to this RH9.0 and i haven't been able to set up my dialup service. Can anyone walk me through this, plus, is there anyway i can make sure my modem is setup correctly. I tried to just dial up any number and couldn't. Thank you all who can offer some badly needed help. Thanks again.

if you want to email me:

first of all is your modem installed correctly? do you have a dial tone and hear it trying to connect?
if not what kind of modem is it? you will have to find some drivers for it.

I am a complete newbie and I just went through the same thing. The easiest way I found was to use wvdialconf, which detects your modem's settings, and then edit the file /etc/wvdial.conf to add the info on what ISP you want to call, and then use wvdial to connect for you.
Hope this can help you somewhat.

How can we help if we don't know what modem you have? :confused:

A pci hardware or external modem is easy. If it's a winmodem, you probably have to find a driver.

# Configuring a pci modem
To configure a pci modem, open an x terminal and su - to the root account:

[phil@fancypiper phil]$ su -
[root@fancypiper root]# cat /proc/pci

Look for your modem in the returned list. Look for something similar to mine:

  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:

[root@fancypiper root]# setserial /dev/ttyS2 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:

[root@fancypiper root]# pico -w /etc/rc.d/rc.local
My file for an example

# 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/ttyS2 irq 5 port 0xc400 uart 16550a

Now, it remains configured after a reboot.

Hey guys, thanks for all the replies, but i think i found the problem. I reinstalled RH and i found out that i have a winmodem. Can anyone help me set it up? From my readings, i hear it's not the best thing in the world for linux os. Thanks for all your help guys. Todd if you'd like to email me

You still haven't given us the specific modem you are using, so it is hard to help without information.

Is it a Conexant/Rockwell?

It is a Lucent Techn.'s WinModem. Sorry about that, i had a brain fart.

Option 1: Search mfg site for Linux driver.
-->Best: Option 2: Open case, pull non-hardware crap out of pci slot and buy a cheap external serial port modem. I find they connect better and have better d/l speeds than even internal pci hardware modems.
