Looks like NMEA stuff. I haven't found the NMEA specs on line. Looks like they (nmea.org) want BIG$ for it. I have found various pieces in specs from various manufacturers that use it. I think the PM is either a manufacturer code or a source/dest tag. I didn't have any luck with google when looking for the GLK sentence. Maybe I didn't ask the right question. > On the sending side, the Odetics sends a series of commands to the > receiver at power-up, all prefixed with $PMGLI.

The normal operation is that they send a set of "sentences" every second or every N seconds. They have some default pattern and usually a tiny flash chip to store the current settings. My guess is the PMGLI is just smashing the GPS card to the "right" mode. -- These are my opinions, not necessarily my employer's.
