[Xastir] New toy, but doesn't work yet.....

[Kurt A. Freiberger]

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
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,3,1,12,14,65,320,,22,63,035,,18,42,084,,31,29,191,*7F
$GPGSV,3,2,12,21,17,154,,09,16,039,,19,14,275,,06,11,236,*76
$GPGSV,3,3,12,30,11,118,,03,08,248,,12,07,085,,26,07,050,*7B
$GPVTG,,T,,M,,N,,K*4E
$GPRMC,,V,,,,,,,,,,N*53
$GPGGA,235945.0,5717.746771,N,05717.746771,E,0,32,99.9,1.0,M,,,,*3B
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,3,1,12,14,65,320,,22,63,035,,18,42,084,,31,29,191,*7F
$GPGSV,3,2,12,21,17,154,,09,15,039,,19,14,275,,06,11,236,*75
$GPGSV,3,3,12,30,11,118,,03,08,248,,12,07,085,,26,07,050,*7B
$GPVTG,,T,,M,,N,,K*4E
$GPRMC,,V,,,,,,,,,,N*53

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
Fri Jun 05 10:56:03 CDT 2009:
         Interface Error!  Error opening interface 1 Hard Fail

         ENOENT ERROR
Fri Jun 05 10:59:39 CDT 2009:
         Interface Error!  Error opening interface 1 Hard Fail

This will be a very cool toy to have.....

Thanks,
Kurt
