Describes a condition of suspended animation in which something is
so wedged or hung that it
makes no response. If you are typing on a terminal and suddenly the
computer doesn't even echo the letters back to the screen as you type, let
alone do what you're asking it to do, then the computer is suffering from
catatonia (possibly because it has crashed). There I was in the
middle of a winning game of nethack and it went
catatonic on me! Aaargh!
