Minix 1.1 and 1.2 didn&= #39;t have them. Unsure of later versions since they aren't packaged ni= cely for quick checking.

Coherent didn't seem = to have them, but=C2=A0it's kinda hard to tell for sure without=C2=A0mo= re study.
=C2=A0
My bet would be to look at ITS, WAITES and Twenex = for the origin story.=C2=A0

=C2=A0TOP= S-20 had a way to attach and detach from a PTY. But they didn't keep th= e state of the screen... programs did, but not the kernel.
