The mount is set up in equatorial mode, using the built in wedge. Before connecting to the driver I make a rough alignment and start equatorial tracking using the hand controller.

From what I've seen in my last test session I am pretty sure that the 4SE firmware can handle these commands. My test setup was the following:

• 4SE mount is equatorial aligned but tracking is off so the mount does not move.
• I open the "Manual tracking tool" in PHD2, which should work with the pulse commands. I configure the pulse length to the maximum of 5s.
• I manually move to any direction using the buttons of the tool and I hear the drive moving for ~5s.

It's possible to get logging data by enabling full logging in the driver, this will show all the commands that te INDI driver sends to the HC.
