It wasn't quite a TSR, it was more like a subshell. I remember using a similar feature in Telix in the early 90s.
It was a bit limited because you were still restricted to the usual 640kB memory space, and the original program remained in memory, so you typically didn't have a lot to work with. You could do things like file management while still connected to a remote BBS though.
