This is coming back.  A little.  The reports meet NMEA standards.  The 
first field determines the data structure.  I think it is GPS for GPS.  
You might also get data in other formats.  I think I was able to 
convince it to give me raw delay data.  Or maybe that was the GPS 
reports.  You might get Loran C reports or others.  I'm pretty sure I 
was able to get Lat, Long, and altitude in some report.  I had to do 
some filtering and averaging and tossing out of data.  I think.

The commands to change the reports may be non-standard and proprietary.

Look at ship standards, I think.

(Or maybe I dreamed all this; use a clue only.)

Because of the ship-board emphasis on serial, I'm thinking the chance 
of the GPS UPS drivers creating a serial view is good.
