ABSTRACT:
A method and an apparatus for emulating a console at a graphics workstation terminal uses a second central processing unit to perform the console emulation. A windowing system operating on a first central processing unit interfaces with the operation of the console from the second central processing unit to provide non-destructive console emulation at the workstation terminal. The windowing system maintains a separate console window that the second central processing unit can access transparently to the other windows. The first or host cpu can still perform graphics functions while the second cpu operates the console.
