gps-debug

The gps-debug is a program monitors the GPS data stream, prints out verbose status information about the GPS unit, and sets the tri-color LED on the MSB to indicate the GPS status. This program only works with SiRF GPS modules using the binary protocol. The debugging output is useful only if you have some knowledge of the SiRF binary protocol and how GPS works.
