Get a USB to serial converter, wire pins 2, 3, and 5 from the converter to the header on the board. I don't remember the pin numbers on the header .. I'll have to look tomorrow when I get home.
Communications is 115,200 baud, no parity, 8 data bits, 1 stop bit. Use a terminal program. Hyperterminal was included for free with XP. I don't think it comes with anything newer. there are many free or cheap programs that will do terminal communications. Many (not all, sadly) USB serial converters have a link to a terminal emulator in their documentation.
When your new board boots up, you should see the firmware version on the screen after a few seconds. If you don't you may have wires backward or not connected well.
From there, you can press enter to get a prompt.
