Starting from a clean Raspbian installation:
<ol>
<li>Use raspi-config to enable the serial port (or add enable_uart=1 to config.txt) and reboot.</li>
<li><span class="mono">sudo apt-get install screen</span></li>
<li>Connect the three wires of the RS232 adaptor to pins 6, 8 and 10 of the Pi's header, and plug the USB plug into a free port on the Pi.</li>
