This type of input is followed by pressing the Enter key. Abort input at any time by pressing the
ESC key. Invalid input keys cause an error message to be shown on the terminal.
The Terminal Control Mode supports serial baud rates of 150, 300, 1200, 2400, 4800, 9600,
19200 and 38400. The connection must be set for 8 data bits, 1 stop bit and no parity (8,N,1).
Three terminal emulations are supported: VT-100, WYSE 50 and ADDS-VP.
Use the character $ for setting the screen when the terminal is used for the first time. The non-
volatile memory is reset.
3.3.4 Modem Setup for Terminal Mode
Terminal Mode communications and protocol are set from the Web browser by setting the Control
Mode parameter to Terminal. Then, set the Modem Port, Term Baud and Emulation Parameters
as desired. Next, connect a terminal to the J1connector.
All operating software for the Terminal Mode is contained in the DMD1050TS modem internal
control software.
These actions initiate full screen terminal mode printing and redrawing of the full screen: a break
signal on the communications line, pressing ESC on the terminal, or Power On of the modem.
The Terminal Mode shows the status of all user parameters controlled and read by the processor.
It offers a menu that allows changes 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 Web browser matrix columns. Use this screen for
setting the parameters of the Modulator, Demodulator, Event, Alarm, Latched Alarm and Interface
areas.
The Terminal Control Mode is menu-driven. The permitted values for each item number are
shown. To change an item, enter its number and press the Enter key. If the parameter to be
changed requires a numeric value, enter the number and press the Enter key. If the parameter is
non-numeric, press the Space bar to cycle through the list of available entries.
Items that do not have ID numbers are Status only, and cannot be changed.
