- Actually, any keystroke is a hardware interrupt. There's nothing
- particularly special about CTRL-ALT-DEL.
-
- You've hit upon what the result will probably be, namely that
- CTRL-ALT-DEL will have to be struck twice, but its basic function will
- be preserved.
-
- From what I've been able to gather, IBM was severely annoyed that
- Microsoft decided to redefine CTRL-ALT-DEL. I suppose IBM's viewpoint
- was that CTRL-ALT-DEL (on a single user system, anyway) should be
- preserved as the "I've fallen and I can't get up" key, and do an
- immediate, safe reboot (it does). Other keystrokes (e.g. CTRL-ESC)
- should be used for task switching and shutting down tasks.
-
- However, for better or worse, Microsoft has redefined CTRL-ALT-DEL
- (although they probably weren't the first). You may have noticed that
- the Service Pak introduces a warning message when you use CTRL-ALT-DEL
- indicating that the system is rebooting. I expect this will evolve to
- something like, "Press CTRL-ALT-DEL to reboot or ESC to abort." I
- think that's the best solution -- CTRL-ALT-DEL is a bit too dangerous.
-
- Reviewers have complained that OS/2 doesn't seem to offer the
- CTRL-ALT-DEL facility in Windows, whereby it can shut down errant
- applications (sometimes). It does, in fact. CTRL-ESC is extremely
- robust -- this is a protected operating system, after all. I suppose
- IBM felt that an extra keystroke wasn't required to convey robustness
- (whether it actually exists or not).
