With SCO UNIX 3.2.2 onwards there is a simpler solution to this.
>From 3.2.2 onwards cu supports an escape that will run a command
with it's standard input and output redirected to the communications
line to the remote machine rather than the local tty (which is what
the ~!command escape does). The new escape is ~+command and I'm afraid
it is only available in 3.2.2 onwards.
