Plug in the RS-232 0 port to a pc via NULL modem and then look at the Device manager for Communications Port (COM x) under Ports (COM & LPT). Attach a terminal program like PuTTY to the serial port (COM x) for the board, x means which COM is open for Communications Port in Device Manager. The serial parameter to use is 115200 Baud rate. Once connected, turn on the device Power button and you should see the am335x getting initialized on the terminal.
