Which TOS? I had a look at this some years ago and TOS writes directly
into the screen buffer, when drawing the Fuji-logo. Maybe this changed
with TOS >= 4, but I doubt it.

As I remember the specs, it's not possible to open an virtual workstation.
Well, it is, but you should not be able to use it.

AES is not initialized, when a program runs in auto ordner, so graf_handle
would return a random value and without luck, it would crash the VDI.
What you described is what you have to do, if a program already owns a
physical workstation.
