3. Installing a modem driver
You have not to read this section entirely; just read one matching with your modem. For the moment, it just describes how to install a LT Modem, using the Lucent and OpenSource driver. If you have written or used an other Winmodem driver, Open or Closed Source, you can email me (alexandre12@mageos.com), and I will include it in this section.
3.1 ltmodem 5.78
URL: http://www.tux.org/pub/dclug/marvin/ltmodem-5.78e.tar.gz
Author: Lucent
License: Non-GPL
Supports: ISA/PCI modem, with a Lucent chipset (Mars family)
Features: Kernel module; simulate a serial port. Does PPP, Fax and Voice
Current Version: 5.78e
Documentation: README-1ST
Requires: 2.2.x or 2.4.x; ISA PNP Support; Loadable module support; C Compiler
How-to-use: Read README-1ST. It is very clear.
Problems:
- Unresolved symbols: xxx_isapnp_xxxx: run modprobe isapnp.
- Device or ressource busy: your modem is not compliant with the driver
3.2 The LT WinModem (from Lucent) 5.68 (OBSOLETE)
URL: http://www.linmodems.org/linux568.zip
Author: Lucent Technologies
License: Non-GPL
Supports: ISA/PCI modems, with a Lucent chipset (Mars family)
Features: Kernel module; simulate a serial port. Does PPP, Fax and Voice
Current version (as far as I know): 5.68
Documentation: README
Requires: A 2.2.12 or higher RedHat kernel; loadable module support
How-to-use: Unzip the package ('unzip linux568.zip'), and run ./ltinst. That's all !
Problems:
- 'insmod: ltmodem: Unresolved symbol(s) *****': You have not a kernel matching with ltmodem. Get the 2.2.12 kernel from ftp.kernel.org, compile and install it
- 'Warning: kernel version mismatch...": It is simply because ou have not the 2.2.12-20 kernel. It's only a warning, and it doesn't make the modem failing
- 'ltmodem: init_module: device or resource busy':
- You have no lt modem or compliant installed
- If you have a ISA modem, it is not configured by isapnp
- If you have a PCI modem, the PCI support in the kernel was not configured
3.3 The LTMODEM program (OpenSource driver)
URL: http://www.close.u-net.com
Authors: Richard Close and Pavel Machek
License: GPL
Supports: ISA/PCI modems, with Lucent chipsets (Mars family)
Feature: User-space driver; does Voice calls; does not PPP (V90)
Current version (as far as I know): 0.99
Documentation: README
Requires: GNU C Compiler, automake
How-to-use:
- PCI: make ; make install - Then use the 'ltmodem' program to communicate with the modem
- ISA: (read the README.ISA file) mv Makefile Makefile.PCI ; mv Makefile.ISA Makefile ; edit config.h and change for the correct values for your modem (I/O Address, DMA, IRQ) ; make ; make install - The use 'ltmodem' program to communicate with the modem.
- "Sorry, I can't found any modem...":
- You have not LT modem
- You have an ISA modem not configured by isapnp
- You have an ISA modem configured ; but ltmodem was not compiled as ISA
- You have a PCI modem with no PCI support included in the kernel
- You have a PCI modem and a compliant kernel, but ltmodem was not compiled as PCI
