I am running
KStars 3.4.2 (2020-04-13 build),
Ekos (not sure how to find the version in Ekos, but I just installed a couple days ago),
indi_lx200fs2 v.2.2 interface 5.

My FS-2 controller is running 1.21.

I read on a previous thread that the mount doesn't receive a "stop" command after parking, and this looks consistent with both my debug logs and a quick peek at LX200FS2::Park().

My questions are these:
1) Is the current driver written only to support a newer version of my firmware? My understanding is that 1.26 is out, and I'm in the process of seeing if I can get a new EEPROM shipped.
2) Is it possible for me to use an older version of the driver that works with v1.21 firmware?
3) I also found a thread that showed the LX200 commands to use to stop the mount -- I'm happy to write the code and submit a PR, but I want to make sure that I don't stomp any one else's config, and I've not edited an INDI driver before.
