No, it is different and that is just the point. Nobody runs RS-232 
between buildings, do you? If we don't go as far as using fibre then we 
would use a balanced line drive like RS-422, but never ever RS-232. Yes, 
I still want to run those distance, but no, I am not stuck in the 60's 
because I use RS-422/485 or some other means.
