Conexant Modem Help

fatherg · 04-05-2004, 07:55 PM

Hi I am currently switching from windows to linux. Right now I'm running Redhat 9. I just bought a shiny new HCF Conexant 56k modem, and when i plugged it in, kudzu recognized it and i chose to 'configure' when prompted. I have since checked the 'hardware browser' and the modem is nowhere to be found. It does show up when i run /sbin/lspci tho.

Unfortunately this must mean that i don't have drivers for it, and of course i look online and find that there are drivers which are $15 to download(linuxant.com) I find this irritating when the drivers for windows are free. linuxant however, has a page dedicated to bullshitting around this notion. Anyway, I just spent $40 on this modem, and i could have bought a US Robotics for the price of the driver and the modem... my question is, if i take my conexant 56k modem back, and get a us robotics modem instead, am i likely to have the same problem? Thx for any help, and if anybody wants to send me a free conexant rpm for redhat and solve the problem that way I certainly wouldn't complain...

You can't go wrong with an external serial port modem.

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

Code:

[fancy@tinwhistle fancy]$ su -
Password: 
[root@tinwhistle 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@tinwhistle 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:

Code:

[root@tinwhistle 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/ttyS2 irq 5 port 0xc400 uart 16550a

Now, it remains configured after a reboot.
