The comport communication is initiated by the 'MyFileHandler=CreateFile(....)' function. Overlapped mode is used. It all seems to work fine, but, if 0x00 characters are received they are NOT detected by my application. The 'WaitForMultipleObjects' function does not initiate an event. The GetFileType(MyFileHandler) returns FILE_TYPE_CHAR. Does this mean that by definition 0x00 charaters can not be handled because they act as an END-OF-STRING character? Anybody has any experience or idea? Thanks Henk Back to top Henk van Winkoop Guest Posted: Mon Dec 05, 2005 9:36 pm    Post subject: Re: Comport receiving Well let me answer myself. After many hours and searching the web I found out it was my fault I had set the DeviceControlBlock.fNull bit to '1' so 0x00 characters where ignored. euhhh...... ;-) Anyway, thanks for listening.
