Interface Informatique

/!\ DOUBLE POST /!\ (je m'auto modere ^^)

finalement j'ai réussi a faire fonctionner le code du site, juste un affection qui servait a rien

donc voila le code fonctionnelle : (tester sous Code::Blocks, Win7 64bits)
je meterai en ligne mon application de console et un mini manuel de fonctionement, pour l'ajout et/ou l'ajout de modification de comande de controle

Serial.cpp
