This document describes the setup for a vt220 to work with the enclosed
termcap on 4.2bsd UN*X. The vt220 is operated as a vt100 except when
the extra function keys are needed. The reason for operating in vt100
mode is that in vt220 mode the ESC, BS, and LF keys are not operational.
If desired the termcap could be modified to use the left arrow as a
backspace key (:kb=\E[D:) and then run in vt220 mode, but it's nice
to be able to use the ESC key when required.
If you are a RAND editor user and if you choose to use the vt220 in native
vt220 mode, the .randrc file provided will have to be modified to not
reset the vt220 to vt100 mode after the edit session is ended.
(More about the .randrc later).
-------------------------------------------------------------------------
SETTING UP THE TERMINAL:
Setup the vt220 as follows using the set-up menus on the terminal:
DISPLAY: 80 columns
Interpret Controls
Auto Wrap
Cursor (gotta see it)
GENERAL: VT100 mode
VT100 ASCII
User Defined Keys Unlocked
User Defined Features Unlocked
Numeric Keypad
Normal Cursor Keys
No New Line
COMM: 7-bit EVEN PARITY (this is a must)
KEYBOARD: Auto Repeat
Break
No Answerback
These options are required - the ones not listed are up to the user's
discretion.
-------------------------------------------------------------------------
SETTING UP THE TERMCAP:
Now the termcap (one entry per line to make it easier to understand):
#DEC vt220 TERMCAP for terminal operating in 7-bit vt100 mode
#The terminal must use EVEN parity

The termcap sets up the vt220 as a vt100 with automatic margins, and
assumes that the terminal is setup (as described above).
----------------------------------------------------------------------------
SETTING UP THE RAND EDITOR STARTUP FILE (RAND editor users only):
The following .randrc file allows the vt220 to be used as a suitable
workstation for the RAND editor. The keystrokes are set up to look
like WORDSTAR with the exception of the CTRL-Q sequences. The vt220
operates as a *true* vt220 while in a RAND session, with the terminal
being switched back to vt100 mode at exit. The reason for running in
vt220 mode is that all the function keys are available, while in vt100
mode they are not. Since the vt220 plays games with CTRL-Q (x-on) it
is necessary to map all RAND sequences to function keys if you want them
to work. The CTRL-Q/CTRL-S keyins do what they should - start and stop
the screen display. By looking at the .randrc you should be able to see
what keys are mapped to what RAND functions. If you are not used to
using a .randrc to make the editor look like WORDSTAR, then you probably
won't want this .randrc. Here goes:
dv vt220 VT220
instring = \[[62;1"p\[>\[[?3l\[[?4l\[[?5l\[[?7l\[[?8h
end string = \[[61"p\[>\[[?7h
auto margin = 3
