This is one of those rare posts that gives information instead of asking for it. I received a reply from eriksmartt elsewhere about setting up a Bluetooth Terminal on OSX since it isn't covered in the Python for Series 60 Documentation.
1. Pair your phone using the Bluetooth Setup Assistant. No special services have to be chosen, just get the phone and your computer to exchange a passcode.
2. Create a Serial Port using the Bluetooth Serial Utility. Incoming, RS232, name: bt_console (anything works but this is what you are using it for, right?!)
3. From the Terminal Application, type: screen /dev/tty.bt_console
Now run the BT_Console script on your phone as indicated in the PDF documentation and everything should work fine.
