GPS Port Checker

GPS Port Checker is a simple application which inspects the ports on a system searching for an attached GPS. These types of GPS are searched for a Garmin USB GPS attached to a USB port, a Garmin serial GPS with the interface in the GPS set to Garmin mode (in older models this is called "GRMN/GRMN Host" mode) and the GPS must be connected to a serial port (also known as a Com port), and a Garmin GPS with the interface in the GPS set to "NMEA Out" mode. A Magellan GPS must be configured to output NMEA data. With all other GPS types all Serial Ports are scanned looking for NMEA data. Therefore the GPS must be outputting NMEA data if it is to be found.
