Refer to Remote Protocol Manual for terminal screens.

4.5.1 Modem Terminal Mode Control

The modem can be interactively monitored and controlled in the Terminal Mode, with a full
screen presentation of current settings and status.
The Terminal Control Mode supports several baud rates, however the connection must be set for
8 data bits, 1 stop bit and no parity (8,N,1).

4.5.2 Modem Setup for Terminal Mode

Terminal Mode Communications and Protocol is set from the Front Panel Control by setting the
"Control Mode" Parameter to "Terminal", and then setting the "Modem Port", "Term Baud" and
"Emulation" Parameters as desired. Then a terminal is connected to Connector J20 on the Back
Panel. All operating software for the Terminal Mode is contained within the 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.

Terminal Port User Interface

The Remote Port (J20) of the modem allows for complete control and monitoring of all
parameters and functions via an RS-232 Serial Interface. 'Terminal Mode' can be entered from
the front panel by selecting "System" and then "Control Mode" followed by "Terminal". The
baud rate and evaluation type can be changed at the front panel by using the System>Baud Rate
Menu.
The Terminal Control Mode is menu-driven and the allowable values for each item number will
be shown. To change an item, type in its number followed by <ENTER>. If the parameter to be
changed requires a numeric value, enter the number followed by <ENTER> If the parameter is
non-numeric, press <SPACE> to cycle through the list of available entries.
