Anibody can tell me the diferences betwen V3.1 and V2.0? Or better,
who have the NMEA 183 specs can send me a copy?


The NMEA specs are copyrighted material and can only be obtained, at a cost,
from www.nmea.org.


I'm a little confused about this. There are numerous explanations of
the NMEA sentences on the net, examples are Peter Bennet and Glenn
Baddeley's web sites:

http://vancouver-webpages.com/peter/nmeafaq.txt
http://home.mira.net/~gnb/gps/nmea.html

Those seem to contain most or all the NMEA 0183 information that anyone
would want. If you paid NMEA's sort of costly membership fee and
acquired their not too cheap specs, what more would be gained by doing
that?

Do you have to be a NMEA member to use the standard in firmware? Or
software?
