I've built that interface circuit and it does work. Hyperterm
definately wont do the job. Larry must be confusing Seatalk with
NMEA.



No, you can see the streams of Seatalk with hyperterm....

If there is NOISE OR RF INTERFERENCE OR SOME SEATALK GOING CRAZY
Hyperterm will fill with graphic gibberish! You don't have to decode
the Seatalk to see the crap in there with it....

Wrong. It's a binary protocol and the signal levels are inverted from
RS232. There no ASCII characters involved in it. Read the document that I
posted the link to in rec.boats.electronics. If there's anything readable,
it's only by pure chance.
