You might try looking at the source to LS 3.1; it was posted recently.

The pr_ConsoleTask pointer in the Process structure is a (real)
pointer to the pr_MsgPort field in the Process structure of the
console handler device -- i.e. CON:...  runback replaces this field
with a pointer to NULL: instead to background programs more
effectively, so a program openning "*" won't hold the window open.  If
you just want to talk to the console, you can open "*", but it's
probably nicer to use Output() instead.
