using gnome-ppp i was able to connect to verizon’s cdma network using the v640 card. all i literally had to do at this point was plug the card in, start gnome-ppp, click on ‘detect’ so it’s not looking at /dev/modem, and done. (i did set the speed to 115200, i’ll have to rtfm to see if that’s too low)

flipp@borked:~$ ifconfig ppp0

update: edit /etc/ppp/options and add ‘lcp-echo-interval 65535′ (or set it to 0). i was only able to stay connected for 2.5 minutes w/ the default (i believe it was 30)

i’ve had the v640 card for awhile, just needed to wait for my expresscard to pcmcia adapter. surprisingly enough, my dell latitude d620 is listed as supporting the card. ha! atleast i have a small warm-fuzzy about this possibly working in ubuntu and not having to just use it inside a winxp vm.

after plugging the adapter in, and then inserting the v640, the output of `dmesg` verifies that the system does see the v640.

i am curious why the card attached itself to ttyUSB0 and ttyUSB1 though. `ifconfig` doesn’t show any new devices either. after checking del.icio.us for bookmarks tagged v640, i can either start configuring the v640 manually, or use a gui ppp client to connect with the v640. one thing i should have done was actually read the bookmarks while i was waiting on the card. i have no clue what the 10-digit verizon number is that is associated with my card. boo. guess this is on hold till i figure that out.
