Here is a termcap for the Radio Shack TRS-80 Model III,
running under Tandy's VIDTEX+ smart terminal software.
This termcap is adequate for vi and, as far as I can
tell, for emacs as well. VIDTEX+ is probably simulating some
known terminal, but I don't know which one.
I keep this termcap in a file in my home directory
called "myterminal", and setup the shell variable TERMCAP to
access it by including the line
TERMCAP=$HOME/myterminal; export TERMCAP
in my .profile file. To use vi, I include
VISUAL=/usr/ucb/vi; export VISUAL
and initialize window size and word wrapping for my screen by
EXINIT='set window=15 wrapmargin=2'; export EXINIT
NOTE:
If you have not specified a "wrapmargin" for vi, it is
important to disable the word-cleaning function of VIDTEX+ when
running that editor (i.e., to use the VIDTEX command meta-B
[up-arrow + B] which allows word breaking).
If this is not done, when, for example, vi redraws the
screen (^L), what you see will not correspond to the editor's
own screen map, and cursor movement commands will appear to
work quite peculiarly. Whether something like this holds true
for emacs as well, I don't know. I tend to use vi almost
exclusively.

This termcap corresponds to a 16 line x 64 column screen
with automatic line wrapping at the right margin (am) and
standard backspacing by ^H (bs) which wraps from column 0 to
the last column of the preceding line (bw).
Standard escape sequences are provided for cursor
movements and screen clearing:
escape-C = non-destructive space (nd)
escape-A = upline (up)
escape-B = down one line (do)
escape-J = clear to end of display (cd)
escape-K = clear to end of line (ce)
escape-j = clear screen (cl)
escape-H = home cursor (ho)
Cursor positioning by row and column (cm) uses escape-Y,
followed by the row number and the column number offset by a
blank character [=20H].
The left arrow key sends ^H (kl); the right arrow key,
^I (kr). Under VIDTEX+, the up- and down-arrow keys serve
control functions.
Most of you probably knew most of this already, but
I'm including all the minute details anyway, in case there are
some other folks like me out there. I logged on cold a couple
of months ago knowing *nothing* about Unix, and what you see
above represents many hours of grubby exploration and
discovery work. If I can spare one new user that, it's worth
it.
