Spawning a console in Windows (similar to forkpty on linux)

[wobbles via Digitalmars-d-learn]

This isn't specifically a D question, but seeing as it's for a D 
library I figure it can go here :)

On Windows, I want to be able to spawn a console and then 
interact with its stdin/out asynchronously, similar to how 
forkpty [1] works on linux.

I'm improving my dexpect library [2] to work with windows 
machines and this bit has me stumped. There doesnt seem to be 
much info about it that I can find (though my google-fu mightn't 
be good enough!!)

I'm sure theres someone here who knows something?

Thanks!
