In a blocking design this wait loop would of course not have been

But here the program's GUI stops working, as the software hangs in the
blocking read or write,
So IMHO, the only decent way to handle a serial interface is doing
blocking communications calls in threads and fire events in the main
thread (e.g. by Application.QueuAsyncCall (avoiding the "Windowish"
PostMessage() stuff ) ) .
And here, of course, you do need buffers to transfer data between the
main thread and the threads
