It's nothing to do with mush, Bart.  Sorry to have bothered you.

The tty driver in SCO System V/386 3.2.0, with ISTRIP on will
match a 0x80 from the keyboard with the 0x0 that the suspend character
has been set to (ie. when not in use) and send a SIGTSTP to the process.

Now, can someone tell me whether this is right or wrong ?
What does BSD do in this case, and what does POSIX say ?

My mush binary was compiled under Xenix, which *doesn't* have
SIGTSTP, and I don't have a jobcontrol shell yet, so the process just
stopped where it was. :-)
I didn't notice the 'T' in the ps listing before -- I'm not
used to stopped processes in a System V format ps output :-)
