/*
 * This is the bridge between the GPSBabel and globalsat sport devices
 * gh625XT. Globalsat has a few devices under the sport brand and they
 * are using a similar USB serial protocol.
 * Currently only gh625XT is supported by this driver but the code could
 * extended (maybe autodetect) support more devices in the future.
 *
 * The code is based on GH625XT-COMMUNICATION_SPECS_20111205-1.pdf from Globasat
 * that they nicely supplied on request.
 *
 * Usage examples:
 * gpsbabel -i globalsat -f /dev/ttyUSB0 -o gpx,garminextensions -F xxx.gpx
 * gpsbabel -i globalsat -f /dev/ttyUSB0 -o gtrnctr,course=0,sport=Running -F xxx.fit
