Hi everybody,
I have a brand new NYX-101 (Pegasus) mount and it worked almost perfectly with the [indi_lx200_OnStep] driver (v1.17 from indi-1.9.9) on a M1 Mac. Only I had problems with the Ekos MOUNT CONTROL pad, it didn't move the mount in any direction.
After digging a bit in the code I've seen that the function to send commands to the mount should be sendOnStepCommandBlind() and not simply tty_send_string() because a mutex is needed to work correctly. Then I have overrided functions MoveNS() and MoveWE() on lx200_OnStep.cpp to use the correct function and now it work Ok. I've attached the modified files.
I don't know it that is already fixed in git or in an other branch or if it is a common problem, but may be any of the developer can be interested and they can add the patch if necessary.
Bests,
Alberto.
