It is mostly the guiding pulses I am interested in, when it is possible to send them via the mount and not via ST4 then I could use a simple camera that I have here for guiding instead of building an USB-based Arduino ST4 interface.
I will try if eqmod also works for me and will report back here.
The only thing I do not understand is that when eqmod actually works a little better why Star adventurer was aliased to the Az Driver. But perhaps that has to do with the possibility to use WiFi to connect and not Serial via USB.
