If the 1 or 1.5 stop bit end is sending data full bore with no time between bytes, then the 2 stop bit end _should_ report a framing error. In many cases there is space between the bytes, so it's not an issue, but I certainly wouldn't want to base the stability of my system on this shortcut. But the reality is that you can only "guess" what the stop bit length is with a microcontroller in the middle. If two bytes are never sent in sequence with no space between them, you'll never know the stop bit length. -Adam - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
