No. We are talking about serial ports, which are very slow anyway. > that is why I refactored the buffer handlers > so you can do. Did you measure any actual performance improvement ? A function call is at most like a few instructions, i.e. the order of a nanosecond. On serial ports, at the very very best, characters take an order of a microsecond to transfer. Again, complex code is really not what you want in the end if it doesn't bring much improvement.
