VT220

P >

The v1220 video display terminal combines advanced capabilities with human
engineering to give you a high-productivity tool that’s remarkably easy to use.
This monochromatic text terminal includes all the capabilities of Digital’s vr100
video terminal as well as convenient new features, such as 15 programmable
function keys and selective erase.
Human engineering makes the vr220 terminal comfortable to work with, so it
boosts your productivity. The keyboard is the best height for efficient typing.
The three keypads and function keys are separated and arranged in a layout that
is logical and easy to use. This helps reduce fatigue and eliminate errors. Plainlanguage setup menus (available in English, French, or German) make it easy for
first-time users to operate the terminal.

The v1220 terminal is truly international, with multinational character set support, multiple language keyboards available in normal (typewriter) or word
processing versions, and a universal power supply.
The combination of advanced capabilities and human engineering make the
v1220 terminal a high productivity tool that can be used in almost any environ-

ment in the world.

to run on Digital and many nonDigital host computers. It can operate
in vr200 mode (7-bit or 8-bit controls), vr100 mode, and vr52 mode.

Except for v152 mode, all modes support standard AnsI functions. The
V1220 can connect to a host computer
