In my ignorance of how ptys map to Windows console objects, I held off from asking for this when Mr. Eizenhoefer solicited ideas, but this is what I thought of at that time, too.

In other words, this notion of “virtual terminals” is already implemented multiple times, following a standard that specifies the expected semantics — POSIX — so why not just do that?

Why, in the end, can Windows *not* have ptys?
