Well, I should say that it might not work in RSTS/E. RSTS/E were more 
limited than RSX in many ways. This might very well be one of those cases.
I think that in RSX, the interactive stuff makes use of an additional 
process. And that's not really possible to do with RSTS/E since each 
terminal only have one process.

But I haven't tried (or can't remember). I haven't played much in RSTS/E 
in a long time.
