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.
