Next Previous Contents 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 The LT WinModem (from Lucent) URL: http://www.linmodems.org/linux568.zip Author: Lucent Technologies License: Non-GPL Supports: ISA/PCI modems, with a Lucent chipsets (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 3.2 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): 0.9.2 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.
