Emax

Fantastic !

...seeing my test program actually say "successful" :-) !
I hope the upload will work too, that's the more interesting one of course.

So don't hesitate to send me the prototype !
I'm almost done with the next version of EMXP (v207, SoundFont2 translation support), which means I will have time for this RS422 stuff very soon ! 

Good work.
