Lucent Winmodem may work with KNOPPIX

[funkea]

Please can someone test this, and fix any error you find - perhaps this can later be used at the hardware FAQ of knopper.net. Thanks!

I wanted to browse the internet while running KNOPPIX CD, and I was disappointed by not having a real modem. Since I have previously installed linux drivers for lucent-based winmodems (ltmodem) in HD-based linux installations (Mandrake, Conectiva), sometimes successfully, sometimes not, I developed a small guide to the subject:

INSTALLING LUCENT-BASED WINMODEM DRIVERS IN KNOPPIX

1. PREPARE YOUR BIOS
- Plug-and-Play OS = NO
- Turn on AC97 onboard modem controller (if availble)

2. Download ltmodem driver source to your windows partition or to a floppy disk

http://www.linmodems.org
(Lucent/AGERE resources, tar.gz file).

3. Boot knoppix

4. cd /tmp

5. tar -zxvf path-to-the-modem-driver-sources.tar.gz

6. cd newly_created_directory

7. ./build_module

8. Install will not work because depmod and install complain of read-only filesystem (they can't save modules to /lib/modules/2.4.20-xfs). Instead do:

9. cd source
then save lt_modem.o and lt_serial.o to the floppy disk (or vfat partition).

10. Create the following script using a plain text editor (save it to the floppy disk too, with a suggestive name like "modem.sh"; if you save it to another directory, adjust the second line to reflect the right location). Don't forget to make the script executable. For example, if you save it as modem.sh, then run "chmod +x modem.sh", or right-click the file in Konqueror, choose Properties, Permissions, and add "Exec" permissions to the file:

#!/bin/bash
cd /mnt/floppy
mknod /dev/ttyLT0 c 62 64
chmod a+rw /dev/ttyLT0
ln -sf /dev/ttyLT0 /dev/modem
insmod -f lt_modem.o
insmod -f lt_serial.o

11. Start kppp then -> Configure -> Talk to modem.

12. If the previous option works, just add a new dial-up account.

13. don't forget to save your config to another floppy, so you keep the account info for next boot...

14. Should the insmod program complain that gcc 2.95 should have been used instead, "cd" to the "source" directory and recompile the drivers, but after the "./configure" and before the "make" steps edit the Makefile and replace "gcc" with "gcc-2.95"

I used your idea to install drivers for my pctel hsp 56k micromodem. It worked for me!
Please refer to my post under Hardware re: HSP micromodem.

Thanks!

Cool. It would be nice to have a script on Knoppix to automate this. The problem is that if your modem doesn't work and it's the only way you can get internet access, how do you download the driver. Perhaps it could be used together with persistent home and a usb key drive.

Great! It does work indeed for the LT Winmodem!

I had quite some trouble using my modem with the CD version, but thanks to this contribution I managed to get things working.

Thanks,

Thank you funkea very much! Without your explanation I did not know how to start. Than, I was lazy and lucky - I did ./build_module than ./instal2 and ./autoload and modem works! They saved modules to /lib/modules/2.4.20-xfs. Modem is Lucent PCI winmodem.

Thanks a lot, it worked for me, but I had to run "su" before I ran the script and before I ran KPPP, otherwise it gave "Permission denied" errors.

I ran the script and the line with mknod gives me an error Input/output error

I used apt-get to put the lt-drivers on my remaster, but I have no way to test whether they work as is, or if I need to do some configuring for them to work.

I put a shortcut in my autostart folder to run a script that activates my modem at startup. Then when I want to get on the internet, I click on a desktop KPPP icon that connects and launches Mozilla. Here's the script:

#!/bin/bash
# Save this file as modem.sh in /home/knoppix
# Set up a persistent home with Knoppix so files will stay put
# Make a shortcut called Modem on the desktop or in your autostart folder.
# In the shortcut under Execute put: sudo -s /modem.sh
# Check Run in terminal and it will do that as root
# Run this Modem shortcut to dial-up if your modem has not been activated.
# These lines, will be run as root, and activate the Lucent winmodem:
cd /home/knoppix/tmp
mknod /dev/ttyLT0 c 62 64
chmod a+rw /dev/ttyLT0
ln -sf /dev/ttyLT0 /dev/modem
insmod -f lt_modem.o
insmod -f lt_serial.o
# This line changes the user to knoppix, starts KPPP, and connects to MyISP.
# Uncomment the line if you want to use it:
# su knoppix -c 'kppp -c MyISP'
# --------------------------
# Make a desktop shortcut called KPPP. In the shortcut
# Under Execute put: kppp -c MyISP
# Where "MyISP" is the name of your dial-up account
# Run this KPPP shortcut to dial-up if your modem has already been activated.
# Set KPPP to redial on disconnect if pppd always dies on the first try.
# In KPPP, under your account, execute, on connect, put: mozilla
# If you want Mozilla to launch automatically on connect.


I use a custom autostart folder so that Konqueror doesn't launch every time I start Knoppix:
Right click on the desktop, click configure desktop, then paths, to make the change. I use: /home/knoppix/autostart. Then move showindex.desktop out and put the modem shortcut in.

i tried to use your script under knoppix 3.3 unfortunately it didn't work for my ac'97 modem
complaining that the kernel is not suiting to the modules .o ,has anybody got any idea ?
thank you!
