I'm wondering if their is a way from within CDC to command a scope to nudge +/- in RA and DEC at a defined slew rate?

If my gotos are a tad off, and I'm remotely controlling the scope from inside, at present I guess I have to share Comm port which has the physical connect from the PC to the hand controller - either physically or virtually.

A Physical sharing might go...

Under CDC grab control of teh aligned scope, then execute a goto from its skycharts. With a PHD window open get a realtime view if it hit its target well. If it is off, relinguish CDC control of the scope (disconnect telescope control) start Nexstar, skip alignment, set slew rate to say 4 or 5 then press the RA or DEC I want until the object is centred in PHD window. Then you have to switch this off and re-grap control of the scope with CDC for teh next goto and so on.

Under Windows each software utility wants exclusive access to the handcontroller via Comm Port 1.

A Virtual port sharing might go...

Map two logical ports say 8 and 9 to Comm port 1 and allow two applications to both exclusivel grap 8 and 9 respectively, which are all being merged into port 1. I think this would be trouble bound as I'd expect the information flow is two way all the time.

Can anyone suggest the best way forward for me? If there was a simple way in CDC to say nudge that scope in a set direction - that would be incredibly useful!
