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.


Manual says it should be S1=off, S2=on for RX211 and RXV21
