Logging in This section describes how to log into the system. The first step
to logging in is to get to an "ENTER PASSWORD: " prompt.
From a modem, dial into the controller and wait for the modem
to connect. After the modem connects you will be presented with
the log-in prompt. If you don't see the log-in prompt after the
modem connects, you may have to press the ENTER key in
order to see the prompt.
