A bit more info:

I am able to talk to the telescope through the RS-232 port by manually sending commands, and can get the telescope to slew successfully there (:Mn# :Qn# etc). The scope does *not* however respond to the ACK command, but all the other commands work. I found this thread  from a year ago where another LX200 scope didn't seem to respond to the ACK command, granted the scope from the thread was not an LX200 Classic like mine.

Any ideas on why Ekos is unable to slew the telescope if I can make it slew through manually-sent serial commands?
