With a bit of fiddling the Option's COMBO EDGE datacard works great under Linux.

The COMBO EDGE card is a combined EDGE/GPRS and 802.11g datacard.

Here's how I did it...

Plugging the card into the PC-card slot is a pleasure: as soon as it is inserted  the serial port is mapped as a PCI serial interface to a standard port (in my case it was /dev/ttyS14).

If you trawl through system messages you will find that a new "ethernet" interface has been reported also - ths is the Broadcom Wifi 802.11g chipset.

(E)GPRS

Using the serial port is a two stage process:

First you open the port at 57600 baud and send the command:

AT+CFUN=1

This switches on the Radio interface and allows the port to now operate at higher datarates!

You can now close the port and re-open it at  230400 baud or higher.

WLan

Basically this card uses a Broadcom chipset - you can use the Linuxant driver wrapper to load the Windows XP NDIS drivers supplied wih the data card.

That's all for now - I shall work on a full blown HOWTO very soon.
