Panel. All operating software for the terminal mode is contained within the DMD2401 LB/ST
modem internal control software.
A "break" signal on the communications line, pressing "ESC" on the terminal or Power On of the
modem will initiate full screen terminal mode printing and redraw the full screen. The terminal
mode displays the present status of all user parameters controlled and read by the processor,
and offers a menu allowing change to any controlled parameter.
The Terminal Mode uses eight "Screens," each of which have the basic contents of the three
modem monitor and control areas as set in the Front Panel matrix columns. This screen is used
for setting the parameters of the Modulator, Demodulator, Event, Alarm, Latched Alarm, Drop
Controls, Insert Controls, and Interface Areas.
Representations of the terminal screens are shown in Figures C-1 through C-10. These screens
may differ from the exact screens displayed due to changes in software and the presence of
options in the modem hardware. For instance, the presence of a Drop and Insert will result in
added options available on the screens, or additional screens to be available.
