Thanks! :)

I had given up all hope -- this is the second time you've been able to dig
up documentation for me :)))

I figured you (Sun) would be.

Getting the documentation might be good enough for me, though... [exports
it from pine, scp's it tohome machine, reading, reading, reading, "Aha,
AccessX Protocol", mumble, mumble]

Yes, I think sending an X_AccessXSelectInput request and then listening
for XAccessXEvents with the subtype X_AccessXModifierXX might work :)


(I'm writing a hack for text-mode = terminal applications that will enable
them to distinguish between things like ctrl-left arrow and
shift-ctrl-left arrow -- nice for selecting text in editors -- by using
XKeyboard to get events every time the modifier keys change and keep the
newest shift-state around in a variable which gets combined with whatever
escape codes are read from stdin into a 16-bit keycode.  It works well
enough to be useful for XKeyboard and the terminal emulators I have tried
it on.  It's not combined with S-lang yet but it will be.

In short, I wanted something similar to just reading the byte at 40h:17h
under DOS.

A similar hack for the Linux console (the same idea is also used by the
Linux version of Turbo Vision and in RHIDE, a Turbo C++ IDE clone):

[Xpert]Pointers to the AccessX programming API?

[Peter Finderup Lund]

I know, wrong forum :)

XFree86 implements XKB which is newer and better than AccessX anyway ...
but I want my program to work well on old and outdated equipment that only
supports AccessX, such as the Sun equipment my university uses ;)

(Lots of SunRay1 terminals served by three big Sun machines, calling
themselves something like "sun4u sparc SUNW,Ultra-250")

So, can anyone (from Sun or DEC^WCompaq^WHPAQ) point me to some docs on
it?
