If you telnet or socat to the gpsd port (tcp/2947), you can see if it returns the information kismet uses for a lock.

Type "PAVMH" - I don't think H (heading) is supported, but the other three will return ? if not locked, or the lat/lon, altitude, speed if locked.

Meanwhile, the kernel shift past 2.6.20 seems to be creating some annoyances with the cx3110x opensource driver. I may need a new kernel (with a few more exported symbols).

I used to have a patch that would decode the NMEA stream for kismet instead of the GPSD commands. I'll have to see if I can find and adapt it. I also have a few of my own GPSD programs.
