VT220/ANSI Display Emulation
The PEN*KEY 6400 Computer’s liquid crystal display
(LCD) shows PEN*KEY computer and VT220 prompts, and
information you type. Because the VT220 terminal’s screen
is 80 columns by 24 lines, the PEN*KEY computer repre-
sents a part of the information on the larger VT220 screen.
Screen Size
You can select the number of display lines and characters
per line. The options are 3, 6, 9, or 18 lines by 10, 13, 16,
20, 26, or 32 characters per line. To set the screen size open
the firmware and select the following options in this order:
LCD PARMS, SCREEN SIZE.
Screen Modes
The PEN*KEY computer has these screen modes: center
cursor, corner, page, lazy, screen lock, and locked. The
modes present a window onto a standard VT220 terminal’s
80-character by 24-line display buffer. You can set the type
of screen mode through the PEN*KEY computer’s firmware
menus.
