Sorry to break it to you, but your question has nothing to do with C++ 
language (the subject of this newsgroup).  Perhaps you can find a better 
place to ask your OS- and hardware-specific question.  So, to answer 
your question, somebody in the newsgroup dedicated to serial 
communication in Windows (if such exists) would likely know and be able 
to help with your problem, or maybe in the general Windows programming 
forum...
