Will file a PR tomorrow when my wife isnt browsing facebook on that laptop :) Regarding the USB serial adapter, I was supplied it though work a while back. I believe from my rather fuzzy memory we got it though these guys http://www.usbnow.co.uk/Cables-USB_to_RS232_Cables/c1_23/index.html Although I wouldn't swear to it.
