On AIX 5L,
Code the functions for switching between
graphics and text modes
in an appropriate place in the driver itself.
To simplify development and maintenance,
you should create a single table
that includes these hardware definitions
and can be called in the driver as needed.
The
SetGraphics( )
and
SetText( )
routines can then call these hardware definitions
as part of the coding to switch between
graphics and text modes.
