expect script only fails in cron

[Michael Jinks <michael twopoint com>]

I'm in the midst of my first experiment with automated interactive
processes, and I've confused myself again, I think.

I have an expect script which pages me using cu.  It works fine if I
call it from the command line, but when I put it in cron, root gets this
mail:

(header skipped)
spawn /bin/bash 
failed to get controlling terminal using TIOCSCTTYparent sync byte
write: 
broken pipe


I think there's a way to tell expect not to use a controllying tty, but
I've been through the manpage and I can't find it.  Or is something else
wrong?
