Rotator Timeout adjustable?

Perhaps the fault of the ASCOM driver, but with my DIY rotator I am seeing this:

however when the sequence recovers everything is fine without further rotation adjustment, so it seems like just a timeout problem.

This is SGP 3.1.0.452

Targets, with different rotator angles, are working fine, other than this issue which seems to happen at the start of the sequence each night.

That error is being thrown from inside of your ASCOM driver and SGP is merely logging it.

Once we start the move we also ask for the current position and a hunch would be that the driver is not protecting against any overlapping I/O on the serial port. Just a guess though.

OK thanks so much for looking into this.

I do have C# source code for the driver (I didn’t write it) so maybe I can figure something out.

It is an ASCOM hub, with PHD2 and SGP both connected.
