For a dot -- a sharp tap

For a dash - a prolonged scrape

I used to send morse to my buddy in company meetings with a tapping pencil
Folks were so busy yakking -- no one noticed --- Typical message was BS or
GEE

Navy pilots captured and held in POW camps in North Vietnam could
communicate with each other in code while in their cells by tapping on a
wall or the floor.

I have used morse code with a key (ve3gqx) but have always wondered how
people sent and recieved code by tapping on pipes etc.
Can anyone explain how this is done? How does one distinguish between a
dot
and a dash?

tnx
