GM_GPSStartTrackingSerial

Starts tracking a GPS device connected to a serial port. The GPS will actually be tracked on a background thread, so this function will return quickly and possibly before a connection is established.

If a callback function is provided, it will be called on the GPS thread whenever new GPS locations are received and when the GPS tracking state changes.

If you provide a format value of GPS_FORMAT_AUTODETECT , a GPS connection will automatically be checked for on connected serial and USB devices.
