Hi!
As pointed out by @mateuszmacheta CV is quite taxing, and furthermore is not as reliable as the more traditional approaches (Computer Vision relies on visually extracting the text).
Here’s a screenshot of the “Configure Connection” you will have to do with the Terminal Session activity:
Just install the Terminal Activities package in your Studio and take a look.
Using the Direct Connection you could “bypass” the emulater and connect directly to the “source”.
Read up on it here Activities - Terminal Session
The terminal emulator will surely have som sort of information regarding what kind of connection, type, protocol etc somewhere.
