S.O.S was a distress call that was used in MORSE CODE, long before telephones were used. To send a call for help, a telegraph operator would send " ... --- ... " It was simple and universal.
To send for help S.O.S = dot dot dot dash dash dash dot dot dot, repeatedly. If you are traped somewhere just tap S.O.S. on the wall.
