Ok, just tried it.  It does not work.  The command shows up in the
list:

  bindkey | head -1
  "^@"    down-case-word

but nothing happens when I send that character.  It is as if something
somewhere along the input chain is swallowing up that particular
character.  It would seem to be in the zsh chain, as when I run the
command cat -v and press control-space a few times:

  cat -v

  ^@^@^@

In another experiment, I tried to use ^V to escape the ^@ and put the
nul character into the command: no go.  The control-V escapes whatever
character I type *after* the control-@.  If I type control-V,
control-space, then carriage-return, I get ^M on the command line.
The nul character is just swallowed up and ignored.

I'm wondering if it is something with the way zsh interacts with the
HP-UX tty driver?  Doesn't anyone else running HP-UX 9.05 experience
this problem?

Here is the output of stty -g:

502:5:b50:3b:0:3:1c:8:7:4:a:0:1e:502:5:b50:8000003b:3:1c:8:7:4:a:0:1e:ff:ff:ff:4:a:1a:11:13:0:0:1a:ff:0:30:50

If you run the stty command with this as an argument (on HP-UX, at
least), you will end up with the same exact stty settings that I have.
If someone else running HP-UX 9.05 (and doesn't have this problem)
could run stty -g and send me the results, then I could try those
settings and see if problem goes away.
