Hi!
Royal TS v26 for Windows (currently available as beta), is able to run local processes (such as cmd or pwsh) in an interactive terminal (PTY).
There are currently no docs for the properties yet but the easiest way to get this done in rJson is to simply configure one custom terminal in a test doc and look at the XML. This way you can find out the property names and values you need in rJson.
Let me know if this helps.
Regards,
Stefan
