I am just starting using KStars on macOS. I could connect my scope Celestron GPS, my two ZWO cameras but I cannot connect my Microtouch focuser. I selected the right port /dev/cu.SLAB_USBtoUART but INDI Control Panel says that it is busy. To avoid any interference no other devices are connected to KStars. In this configuration Nebulosity and TheSkyX connect to the Microtouch focuser. Interestingly I encounter similar connexion difficulties when I try to connect the focuser to AstroImager (also using the INDI protocol) !
I was informed this was an issue with incorrect baud rate settings and now it is working.
Yes Jasem that was the case. As Peter told me I changed the rate from 9600 back to 19200 and it worked. Thanks
