Terminal Mode Control
The Terminal Mode Control allows the use of an external terminal or computer to monitor and
control the modem from a full screen interactive presentation operated by the modem itself. No
external software is required other than Terminal Emulation Software (e.g. "Procomm" for a
computer when used as a terminal. The Control Port is normally used as an RS–232 Connection
to the terminal device. The RS-232 operating parameters can be set using the modem Front Panel
and stored in Non-Volatile Memory for future use (refer to Remote Protocol Manual for setup
and 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.
