Thanks Ken and Barry. I'm away from that job for a while (got to achieve some other stuff around the place while the weather's good
), but I'll check it out maybe this evening.
FYI Barry ATM there are no COM ports allocated. It doesn't make sense that it doesn't work - since it works on my old XP lappy.
I have in the meantime found a fairly non-descript mini-CD with the only marking on it being "USB". When I had a look, there was only one file on the disk: "Telescope Driver.exe". I'm hoping this might be what I need, but haven't tried it yet.
