This driver (available in the 3rd party catalog) fixes a few tracking bugs in the indi_celestron_gps driver as well as supports direct control via PC Port. It's a beta driver so some option to unlock or accept risks or whatever may be required.
I'm tracking the celestron_gps tracking bug here: https://github.com/indilib/indi/issues/1592 I have a patch that works on my telescope but I want to do more testing before committing to it. (Also it's nearly impossible for me to believe this affects all Celestron mounts, so it may need an option to enable/disable)
