I think we have violently disagreeing opinion on what constitutes
"sane". I have used DEC VT-52 clones, VT-100 clones (and a vt102),
and vt-220s. I'm *used* to the delete-to-left key being ASCII DEL.
What I'm *trying* to do is to set up al lthe mappings to approximate a
vt-220 style approach. Since that's exactly what I have on all my
pmaxes, and it's what NetBSD used, more-or-less, to support.

hat is *precisely* what i'm trying to fix; it's what the current setup
does once I rlogin to my netbsd-1.4 box, or to a SunOS box. Except
that I have DEL mapped to the key labelled "backspace".
I want to set up x keybindings that are vt100/vt220-like.
Then, everything pretty much Just Works. Or at least, it used to, up
until the current batch of changes.

Historically, the VT series *was* the standard. It's PC keyboards
which were/are incompatible :).

Yes, except for the short-sighted, insular, badly-engineered changes
to our xterm (is it all platforms, or just i36? I'm going to be
__really__ unhappy if the <X] key on my pmax LK-401 now generates
ASCII backspace in an xterm.

No, I don't. I get the Esc-[-3-~ braindamage. That's not a
`proper' keybinding: it should be ASCII DEL.

Lucky, lucky, you. NCD did the right for their market, imho.

I thought real VT100s also had a DEL key where PeeCees have backspace?
What, if anything, does the wscons binding have to do with how
X handles keycodes? Do the keycodes as seen by the Xserver
go through wscons' mapping?
And that still doesn't explain how I can get the "Delete" keysym
to generate ASCII DEL. Now, *that* is just broken.
