In article <681@mecky.UUCP> I write:
about vi hanging after I pressed CTRL-@. I was rather stupid,
because the problem was not in vi but in my terminal driver,
which interpreted CTRL-@ as the "suspend" character (thank you
Roger for the email).

My only excuse is the absence of any reference in the manual about
the suspend character: in stty(C) SCO mentions it, but doesn't
explain it, nothing in termio(M). Probably it's the first step 
to job control, but at present, the behaviour is rather strange: 
If I type the suspend character in the login shell, I logout. 
In a subshell, I become blocked as in vi. Only the input echo is 
activ.

My advice to users of SCO UNIX (and to SCO until job controls works):
Disable the suspend char in /etc/profile with stty susp '^-'.
