Bonjour je suis actuellement en train d'essayer de remplacer un programme basic qui controle un robot via le port serie RS232

par un programme c++. Je ne comprend pas, mon programme c++ envoie les commande et le robot ne bouge pas... Pourtant j'ai

r�gl� la bonne vitesse en baud le bon nombre de bits de parit� et de stop et le bon wordlength.
J'ai utilis� le logiciel portmon pour capturer les agissemnts des deux programmes et je ne comprend pas ce qui cloche, les

deux me semblent faire la m�me chose(alors que seul le programme en basic arrive a faire bouger le robot).

Voici ce que m'affiche portmon pour chaque programme

programme en basic :
