Try this:

From a command prompt run empgps.

Press and hold the knob until the hijack menu appears. empgps should be in there. Select it. The serial port should then switch to 4800bps and display the first status page. This will show all zeros initially. Hook up the GPS.

empgps will only appear in the hijack menu while it is running. Rebooting will remove it.

I will put a picker script together to help use this. However, once I have the serial interaction with the player solved it can simply be started at boot (via preinit) and left there.

empgps will only output on the serial port in response to the ASTRAL power up prompt from a Tripmate receiver. Otherwise the data is strictly input.

Cheers,

Rex.
