I think I have this set correctly, can be seen in this photo, unless I misunderstand the colouring. Originally it was the other way around and VTserver would throw an error instead of hang. I can try it again, with the originally settings, under xxdp and see what happens. http://aaronsplace.co.uk/private/pics/rx02insides/logic.jpg Manual says it should be S1=off, S2=on for RX211 and RXV21
