    Rastport variables for console device Text output are stored in
the ConUnit structure.  The console device modifies the variables
in the ConUnit structure when you write the CSI strings.  At the
start of each write, it temporarily copies those variables to
the window's RastPort so that they are used when it calls Text().
To make the console device print text in a color higher than 7,
you would have to store the color number in conunit->FgPen.
I've been told you should surround your code to modify conunit->FgPen
with a DISABLE/ENABLE pair.  Seems like overkill to me, but...
You should be able to find the pointer to the ConUnit structure
in yourIORequest->io_Unit. (OpenDevice() puts it there).

   There is a new 1.2 Intuition function ActivateWindow(window).
To call it, you need to link with 1.2 Amiga.lib.  In addition,
you'll have to specify version 33 when you open intuition.library
so your program can make sure it's being run on a machine with at
least 1.2 OS.  Abort gracefully if the OpenLibrary fails.

   If you don't have 1.2 Amiga.lib, order the 1.2 Native Developer
Update as described another recent posting of mine. 
(Note - if you are using Manx then get a 1.2 Manx update instead)

   You send a false InputEvent.  See the input.device chapter in the
ROM kernal manual.
