This brought back a memory from when I was a kid. A place I spent occasional
time at had a rotary phone with a lock on the dial. Whenever I needed to use
the phone from there, I'd just dial the number "morse code" style. (Being
ignorant of this method, they'd neglected to turn the rotary dial partway before
locking it, which would have prevented a dial tone.) You can still do this type
of dialing with a modern touch-tone phone, since the telephone system still
recognizes pulse dialing. You have to time the pulses right, though, to
approximate the rate at which a returning rotary dial would generate them.
