how do I tell the size of a pseudoterm window?

Err, umm, maybe I missed something, but it sure sounded like Doug Gwyn
said you could achieve what is really desired here, which is to run a
display-oriented program on a machine other than the one to which the
tube is directly physically connected, so the answer is, apparently,
"yes", not "no".  My guess is that the "TCP gateway" in this case is
something like "rlogin", passing characters from the network connection
to the terminal and *vice versa*.

Now, if you had some terminal-based window system that *didn't* allow
that, for whatever reason, the superiority of X over the hypothetical
window system in question would be that such support wouldn't *have* to
be written for X....
