it sounds like he's a little confused about what ctrl-z does... he says he uses it to send the process to the "background", but that's not what ctrl-z does at all. ctrl-z just *stops* the process. while stopped, it can't do anything. it can't respond to input, create output, or receive events from blackbox or anything else. what you need to do to send the process to the background is press ctrl-z and then type "bg", as martin illustrated in his example but didn't point out explicitly.
