getting back to Speckfisher's original post, is there a way to test
NMEA out/in with a meter, or do you need a laptop/software to do so?

You can see if an NMEA device is outputting data using a voltmeter. I
prefer an analog meter, but DVMs can also work, unless they are very
slow reading.

Set the meter to read 5 volts, and, if there is data present, you
should see it wiggling - with the voltage varying around 2 - 3 volts.
The data line will acutally switch rapidly between 0 and +5 volts, but
the meter won't be able to follow it.
