This is additional information related to Roger Perkins post related to the Magellan II not working. My Magellan 1 does not communicate with version 6. This is my first version so I do not know if it worked in previous versions. I connected my Magellan 1 to my laptop's planetarium software and turned on my serial log. Maybe these details will help. The Magellan 1 communicates at 1200 baud. The transmission string from my software to get RA/DEC values was:
# : GR# : GD#
The response from the Magellan 1 is: (just using generic RA/DEC values)
18:11.4#-25b40#
where the b looks like the beta symbol in ascii.
Maybe this data can help the developers make version 6 communicate with the Magellan 1
