Raspberry Pi port, piCore-15.0 is available!
I made a gpsd extension a while back but never submitted it. I'll do that.
i have completed gpsd 2.39 but requires testing
Version 2.39 is about a year old. I built 2.92 (released March 3) simply because it was the latest, but does tangogps require 2.39? As for testing, I have a BU-353, Garmin LVC 18, Garmin GPSmap 76CSx, and one other.
