Having read the thread on Android devices as throttles, I downloaded the Rocrail program. After a bit of cursing and swearing I finally got the program to talk to the controller and move a loco. I have only tried manual control but at some point I'll try automatic and see what happens. The only problem with that is I think I need some sort of feed back sensor and as yet I don't have any. When I get a chance I'll put some details on here.
