sl@0: // Screen Driver for Text Window Server
sl@0: // TO DO: (mandatory)
sl@0: // This is the screen driver for the simple text Window Server supplied as part of
sl@0: // E32. It is required to run the text shell, E32 & F32 tests etc.
sl@0: // This is a working generic implementation which you shouldn't need to alter, but
sl@0: // you may customise it if required. e.g. Change the default display mode or colors.
sl@0: // ASSUMPTIONS MADE BY THIS IMPLEMENTATION
sl@0: // * The start of each character on the display is byte aligned.
