5. FAQ

5.1 I have a winmodem. Will it work under Linux?

Probably not. Please see the section "Which Linmodem hardware is supported?" above, and check the Linux Modem Compatibility database at Rob Clark's site.

5.2 I get a "device or resource busy" error.

If you have an ISA modem, did you use the isapnptools to allocate IRQ and DMA resources to the card? See "ISA Plug-n-Play", above, for more information.

5.3 My PCTel modem doesn't work.

5.4 The modem dials and connects fine, but then it drops the connection.

In this case, the module is most likely installed correctly and is working, but you may have a problem with your ppp configuration. See "Configure your PPP dialer", above, for more information.

It has been reported that, with some kernel/module mismatches, a program like kppp will give this error, while an alternative like wvdial does not, for the same modules and hardware. You may wish to try a different ppp dialer and see if that helps.

5.5 The modem dials and connects fine, but I get a kernel panic on closing the connection.

This has been reported with ESS modems and wvdial. In this case, kppp may work better instead.

5.6 Nothing seems to work. To whom can I turn for help?

If all seems lost, please see the section "Troubleshooting", below , and consider sending a message with the complete information described there to the mailing list at Linmodems.org.

5.7 Who wrote the driver for my winmodem, and how do I contact him/her?

Probably somebody on contract to the manufacturer, who probably does not have the authority the update/release/change the source code, and who probably doesn't have time to reply to your email in any case. See, for example, http://lwn.net/1999/1209/a/lucent.html
