<div dir="auto">I suspect we'll be stuck for with serial interfaces to GPS hardware for quite some time due to the NMEA-0183 "standardization". Many systems use gpsd to talk to actual hardware and supply a processed feed on a network port, quite often on a loopback address for internal use only, e.g. Android and other mobile devices.
