Terminal Mode

980548-001 Rev. A KDU Plus User’s Manual 6/12/06
Overview
The operation of Terminal mode is similar to Windows™ Accessories software program
Hyper Terminal and could be described as generic terminal.
All data typed (and displayed if Echo mode is active) is sent immediately to the
printer.
Printer responses are immediately sent back to the KDU Plus and displayed (if
printable).
Every typed action by the operator is sent to the printer. Typing ‘123’ and then
following that with a backspace will display ‘12’ with the ‘3’ alternating with a
blinking cursor. The printer received the ASCII characters for 1, 2, 3, and backspace.
Custom Applications - Displayed data does not need to match data sent to the printer.
The KDU Plus recognizes ANSI Escape sequences for display cursor control, see
External Terminal Control on page 63.
Debugging with Terminal Mode
The typical reason the KDU Plus is in Terminal Mode is that communication has not been
properly established between the printer and KDU Plus. Common reasons for communication
failure include:
EPL printer does not have the cover closed with media (labels) properly installed.
(Load media and print a status label using AutoSense to verify printer operation).
The operator was running an AutoSense or a Feed Button mode process immediately
upon printer/KDU Plus power up. (The printer is busy and can not respond).
The Auto-Detect feature is turned off and the KDU Plus can not reconfigure the
communications to match your printers settings. See “Port Settings” on page 17.
The KDU Plus’s PRINTER/COM port or the printer’s COM port communication
settings have been changed from default.
EPL - The printer may be running an AUTOFR form. See the EPL2 Page Mode
Programmers manual for details on the AUTOFR command (form).
