Hi all...

Im am doing the following simple line that is running about 40 times a second:
WriteFile(ComHandle, Block, Length, &BytesWritten, NULL);

ComHandle is pointing to a COM port opened at 19200.
Length is never more than 20 (verified).

It will work for a random amount of time then, WriteFile gets called but doesnt return... ever.

Anyone know what the problem could be?
