Of course this is true. However... How many of those emulators and people
really require these particular few DEC VT100 graphic codes? Will their
usage increase over time?

I think that if Digital originally didn't bother with them, they're better
left alone.

Then they should band together and get themselves organized so they can
request the addition of their required graphical segments and line-drawing
stuff. I don't believe there's that much interest.

Of course that's true. It'll just get less like "dumb terminal" emulation.
I don't see a big, continuing market in the 24x80 one-column-one-char
terminal emulator. However, I do see a great long-term need for the
command-line interface and interpretive languages, such as shells, LISP, etc.
 Those just don't require the line-drawing legacy stuff. I use a terminal
emulator all the time, daily -- I almost never need even a rudimentary cursor
positioning interface, and *NEVER* need a line drawing interface to it.
