RS232 ports
(properly designed ones) are fairly hard to damage
electrically.
Well, that depends on what counts as "hard". From one point of view,
it's really easy to damage them electrically - just connect straight to
mains power; few RS232 ports will withstand that, even over here where
mains pwoer is only half the voltage it is on your side of the pond.
