NMEA is just text. Normally, they send a clump of "sentences" every second
so something as simple as hyperterminal should work. If you find something
that looks like lat/long, it probably is.
Some/most devices have a way to turn individual sentence types on/off.
That's usually a proprietary command so you will have to find a data sheet
for your specific device. (or just ignore/filter the stuff you don't want)
These are my opinions. I hate spam.
