John,

Here are the command descriptions:

So Ekos appears to be asking if the focuser is moving and waits until it's stopped. Although, I'm wonder if once the CMD <:00#> is issued and responded to that the focuser physically stops moving. Maybe? It seems to appear that it does based on the logs.

Let's see what Robert says.
