Don't hurt yourself... the diagram wasn't needed
You aren't supposed to press enter twice at BIOS... you need to use a terminal emulator for whatever operating system you have. Settings should then be:
2400-8-N-1
Or replace 2400 with whatever the baud rate is set to on the Jr. Default is 2400bps. Also, just another thought... you should try keeping all of this stuff to one thread. That other one was hijacked so I'm just throwing out my thoughts.
