I was testing a GPS module last night, everything was going well, I received GPS messages via RealTerm. I also tested output to RealTerm via COM2 of my Fez Domino, which also worked fine.
I played with the wires abit and now I can’t get the same results. I get nothing from the GPS module and get gibberish from COM2. (See attached screenshot) - Also I get the ERROR light turning on when bytes are received.
I’ve tried a few different things - trying another USB->serial cable (same result).
Connecting the GPS module on its own to the USB->Serial cable (no output).
BTW, if you don’t already know I have already rendered COM1 IN useless.
I checked the voltage at 3.3V and it is fine. I tried an onboard LED test on the Domino and that works fine.
Have I burnt something else out?
