Subject: UNIX SCO V / 386 --- the final story

Well, friends, the problem with ^@ (set-mark) on SCO Unix appears to
be an incomplete implementation of a very strange abstraction called
"shell layers," which is a poor-man's job control which uses multiple
shells, run by the shell-layer program "shl," instead of putting
job-control into the shell the way Berkeley did.

^@ is the system-default for the suspend character.  You type it and
the TTY driver happily suspends your program and leaves you at the
shell, which happens to be in raw mode.  Typing ^Jstty sane^J will
take you to a regular mode.  

Unfortunately, there is no easy way to get the emacs to restart.

The simple workarround is to type "stty susp ^_" (or put it in your
.login file), so that ^_ becomes the suspend character.  AND DON'T
TYPE ^_!!!!

I now have gnuemacs running on SCO UNIX 386 with no problems.  If
anybody wants the diffs, let me know.
