As a bit of a followup to my earlier post - I've cobbled together a brief howto + driver for the AirPrime PC5220 EVDO card for FreeBSD. The code is just a stripped down version of the existing uplcom.c driver - the EVDO card looks like a serial port, but it doesn't actually need things like dtr, etc., since there's not a real serial device attached. In essense, all the resulting driver does is find the USB device IDs and attach them to a ucom. So the code is kind of ugly and stupid, but I'm sure someone could make something elegant from it. :-) It works - I've had pings running through it for the last day or so - but I haven't tested it extensively. The thread I started earlier about the "remove the card and the machine crashes" bug with the USB subsystem probably makes it a little less attractive until that's fixed too. Tested only under -stable near 5.4 release. http://www.cs.cmu.edu/~dga/dot/fbsd_pc5220/ (If anyone could test it in an EVDO-enabled area and see if bumping the bitrate up in their PPP config just works like I think it should, let me know! You should be able to get a full speed EVDO connection... I think.) -Dave
