Configuring my modem to work with Red Hat

My modem works fine in Windows, but not in Red Hat 9. The modem is soft56k. Can you help me with the configuration?
First you should try to find out what kind of chipset the modem is using. You can find this by listing the PCI devices (I am making an assumption that the modem is s PCI modem). You can do this by becoming the root user and listing the PCI devices using the lspci command. Here's an example of the output from one of my systems.

[root@localhost mrhinkle]# /sbin/lspci
00:00.0 Host bridge: Intel Corp. 82815 815 Chipset Host Bridge and Memory Controller Hub (rev 02) 00:01.0 PCI bridge: Intel Corp. 82815
815 Chipset AGP Bridge (rev 02) 00:1e.0 PCI bridge: Intel Corp.

What you should look for is a line mentioning your modem I don't have a 56K soft modem so I can't be sure what the output will look like for yours, but this will give you some clues to the chipset. I am assuming that it will include Lucent, Conexant, or Aegere as the chipset. Then I would visit the following sites:

  • Linmodems support
  • If your chipset indicates that it uses a Conexant chipset than you may want to check out Linuxant. They make a HSF (softmodem) driver for Linux.

    You may find their scan modem tool very helpful as well. You can download it here.
