I have this strange problem with a serial driver of mine using CreateFile/ReadFile/WriteFile
All characters sent have their most significant bit cleared.
Am I missing something obvious? Have tried to search MSDN and google, but haven't come up with good solutions. Debugging is of course possible, but a bit tricky not having a good Terminal program.
Could supply code, but it is really lengthuy, and I have no idea which part of the code might be wrong (or just bad sync - which I don't believe, as MSb is sent as the LAST one!).
Have tried with bot 1 and 2 stop bits, and with 2400-57600 Baud - the problem is exactly the same. I think I'm going to explode... Oh well
