I think this is possible from Apex 4.0 and later. There is a subsystem - lower_predefined.ss- which implements the "transportation" of your I/O. Check the apex_predefined_io_implementation.os_dependent_io package in there for details. --Fredrik On 2005-03-20 19:01, John McCormick wrote: > For the embedded systems class that I teach, I need to implement > keyboard input and text output to EGA / VGA on a bare metal (no > operating system) AMD (Intel clone) platform.
