probleme port com QBASIC / C++ svpp

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

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

deux me semblent faire la même 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 :
