I'm not sure if I should post this to GpsTools or SerialTools so here goes nothing..
I would like to receive the $PGRMZ sentence from my eTrex as this sentence represents the barometric altitude instead of the GPS altitude. I understand that this sentence is only available when I switch my eTrex over to GARMIN from NMEA. When I do this GPSTools looses it's connection to the GPSr. I have GPSGate so if I can figure out how to get the $PGRMZ sentence from the eTrex on my iPAQ's USB port I can still get all the other data from the CF GPSr and GPSTools.
Anyone know how I can get the proprietary GARMIN $PGRMZ sentence from my eTrex?
