I just got a Sprint AirCard (Merlin EX720) that has GPS capabilities.
It's on a MacBook Pro. I can see the data:
kosh:dev kurt$ cat /dev/cu.wwancntl2
$GPGGA,235945.0,5717.746771,N,05717.746771,E,0,32,99.9,1.0,M,,,,*3B

The permissions of the port are:
kosh:dev kurt$ ls -l cu.wwancntl2
crw-rw-rw- 1 root wheel 17, 11 Jun 5 10:38 cu.wwancntl2
However, comma, when I define it in Xastir, I get an interface error.
It's defined as a Serial GPS on /dev/cu.wwan2cntl2 I left the port
settings and Port Style on their defaults.
Anybody ever done this before? I'm thinking that the ioctls to set the
settings are barfing and resulting in the errors:
ENOENT ERROR
