To: xpert@expo.lcs.mit.edu

I rummaged around through the xterm code and came up with the following
stuff. No guarantees. I'm headed out of town for a couple days and thought
it better to get it out than let it get stale. Comments, bugs, and other
notes are welcome. Somebody else can convert it to troff. I prefer LaTeX.
:-) I will try and get to the Tek mode stuff when I return, although I doubt
it's changed much from X10 XTerm.

I gleaned the basic stuff out of the charproc.c code, by hacking VTparse()
so it spit out leaves of the parse tree. I was mildly surprised to see
things like "ESC # BEL" turn up.

For most folks, the most interesting stuff will probably be "ESC ] Ps ND
string NP" down near the bottom. That's what you use to change the icon and
window labels, and the log file name. Most other things appear the same as
the X10 documentation, although a few DEC-ish mode parameters (42, 43, 48, &
49) seem to have disappeared.
