No surprise. MS-DOS assumed that the active program owned the machine and could do anything. DOS apps tended to write directly to the screen instead of using BIOS calls for compatibility, because BIOS writes were too slow. . Windows really doesn't like you to address the hardware directly, because your program won't be the only thing running, and gets surly if you try, up to and including terminating your program. ______ Dennis https://plus.google.com/u/0/105128793974319004519 ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
