Add  ***NEVER**** use direct RS232 input into a microprocessor pin via  a
resistor and assume that the processor protection diodes will clamp the
voltage swing adequately. In such cases you must ALWAYS ensure that the
voltage never swings outside the processor supply range (or, where
specified, the maximum limits specified by the manufacturer for NORMAL (not
absolute maximum) operation.).
