The GPS data comes in via bluetooth com port 5

And The Cap'n, which I don't think will talk to more than one com port (at
least ours won't), is transmitting your data out on Bluetooth through the
same port.....

Now all we need is a Bluetooth Tillerpilot and we'll have a wireless
networked boat!....(c;

Use a Bluetooth to serial converter.

That'll be about 2025 as slow as the NMEA bureaucrats respond to changes
in
technology. They're still talking RS-422 from 1975....

Oh please, quit with the whining about NMEA, willya? It's gotten more than
old....
