BitCom, a trashy DOS based terminal program, would lower the signal on the DTR pin, which would hang up the modem instantly, when it saw the text, "NO CARRIER" on a line by itself. Obviously, that line got dropped in forums and chat rooms as the "word of the day for BitCom users" on a regular basis.
