Hi Bud , It works !!! INDI was up and running , after installing it with : sudo apt-get install indi When I started Carte du Ciel 3.0.1.4 , I got this error message in Carte du Ciel when connecting : Telescope : Error connecting to port com1 . Make sure you have BOTH write and read permission to your port . I know that the serial port ( com1 in windows ) is TTYS0 in Linux , but that wasn't in the list . I checked in the older discussions and there I found something about the COM1/TTYS0 "error" . In the links , there is a link to version 3beta 0.1.5 . I downloaded and installed that and problem solved !! No more Comx in the list , but TTYSx . I can use either LX200 Basic,generic or classic . They all work . Thanks a Million for your help and inspiration !!
Marc
