Already been down this path. Unfortunately cron has no controlling  
pty and so the script errors with a stty error.

couldn't write file "/dev/tty": no such device or address
     while executing
"exec /bin/stty cols 140 >/dev/tty"
     invoked from within
"stty cols 140"

I tried this by using the stty command within the expect script, as  
expect sees stty as a valid option. from the man page:-
     stty args
              changes terminal modes similarly to the external stty
