I have installed RHL8.0 on my Toshiba Laptop and I am having difficulties with my modem being detected. Below (esp. for CARLYWARLY) is the dump from running lspci (apologies for the formatting):

00:00.0 Host bridge: Intel Corp. 82815 815 Chipset Host Bridge and Memory Controller Hub (rev 11)
00:01.0 PCI bridge: Intel Corp. 82815 815 Chipset AGP Bridge (rev 11)

02:0d.1 CardBus bridge: Toshiba America Info Systems ToPIC95 PCI to Cardbus Bridge with ZV Support (rev 31)

This is contrary to Windows XP's listing of my modem details as a Toshiba Software Modem AMR (which is attached to COM3).

I do not come on (linuxquestions.org) at frequent intervals, so if some help is offered/information is requested, please check back the same time you post information the following day.

Software modems can be difficult in Linux....you probably need some drivers....check out http://www.linmodems.org/ as a starting point
