Affinite, thanks for your help. I just tested the GPS
on the boat computer it was connected to before I started experimenting with the pi. It now spits out the same garbage there as it did here. Either I managed to break it somehow or it has been (somehow) put into a different mode where it doesn't spit out NMEA 0183
but other stuff. It is a BU353 and I seem to recall
that it has some other mode it can operate in. I will have to figure that out first and maybe things will work .... if not I will go through your setup.
