It uses the serial port on the GPIO pins. I have had a lot of problems with USB to Serial adapters on normal Linux systems, so I didn't want to go that route on the Pi.
I haven't written up my blog post on the X10 interface yet, but you can see the other progress I have made on my blog.

- I've downloaded the .tar.gz file from here, and expanded it into a folder (containing 7 files) on my mac.
- I've sftp'd the expanded files into a new folder called sunwait in the home folder of my pi.

Any ideas much appreciated...
