Networking (inc wireless & modems)

Thinkpad Win/Linmodems:
Most of the T21s have the Xircom combo mini-pci card with an Intel (eepro100) ethernet card and a Lucent winmodem. If you have a T21 and /proc/pci has an entry like this:

Serial controller: PCI device 115d:000c (Xircom) (rev 0).
IRQ 11.
I/O at 0x1840 [0x1847].

then you probably have one of these cards.  You can probably ignore the IRQ and I/O entries.

Go to www.linmodems.org for some general information on Winmodems under Linux, or to download the driver directly, go here:

The driver is a binary driver with a compilable wrapper. If you get oopses while using this driver, don't complain to anyone, especially not the kernel mailing list.
