# RINO GPS polling script by Wes Johnston KD4RDB.  April 07 2006               #
# This script uses GPSMan to poll a garmin rino gps unit and detects changes   #
# in the location or symbol used from one iteration to the next.  If a waypoint#
# moves, it will be published to xastir via the xastir_udp_client program      #
# Press <cntrl c> to stop execution                                            #
