That's not quite true. Many Hayes- compatible modems will reset entirely
when DTR is toggled, but the correct response is merely to break the
connection and go into command mode. The reinitialization is a nuisance
which forces most programs to tediously resend any setup commands they
had already communicated to the modem after each call.
