Sending commands between stamp''s (networking)

Djr,
Hooking up two Stamps to talk to each other is easy. There is a complete
example of how to do so in the manual, downloadable at the Parallax site.
Also, search the archive for fuel injector stuff, that has been a thread
many times, and there will be a lot of information there. I have never tried
such a thing, but I hear it isn't easy.
Good Luck!
