This is incorrect; the setting which causes the modem to reset itself
ALSO hangs up.  There is no way to reset the modem without hanging up
(it's not clear that that makes much sense, anyway).

False. The light tracks the state of the DTR line UNLESS you configure
the modem to ignore DTR entirely, in which case the light remains on.

I have had no problems with my Hayes 2400 that are the result of poor
functional design.  It did fail to survive a lightning strike on
the phone pole across the street...
