Module Name:

  Console.h

Abstract:

  Console based on Posix APIs.

  This file attaches a SimpleTextIn protocol to a previously open window.
  
  The constructor for this protocol depends on an open window. Currently
  the SimpleTextOut protocol creates a window when it's constructor is called.
  Thus this code must run after the constructor for the SimpleTextOut 
  protocol
