demon dialer n.
A program which repeatedly calls the same
telephone number. Demon dialing may be benign (as when a number of
communications programs contend for legitimate access to a BBS
line) or malign (that is, used as a prank or denial-of-service
attack). This term dates from the blue box days of the 1970s
and early 1980s and is now semi-obsolescent among phreakers;
see war dialer for its contemporary progeny.
