The answer is the same.  Type `trap "" 2' to your interactive sh or ksh
before invoking `script'.  If your shell is ignoring a signal, its
child will ignore it, too.

The `onintr' directive to csh doesn't seem to have an option to cause
the shell to ignore one signal.  `onintr -', though, will cause it (and
its child, the `script' process) to ignore ALL signals, including
SIGINT.  This will make it more complicated to recover control of your
display if your application hangs.
