- Exactly!
-
- (Of course, a future "enhancement" by Digital to the terminal driver may
- resurrect the bug, or a similar one. It's happened to us before. In fact,
- if I remember correctly, I tried something that looks very much like the
- current "end of call" code under VMS 4.7, and it would sometimes get wedged...)
-
- You will also sometimes see SS$_ILLIOFUNC, illegal I/O function, for a similar
- reason.

- (One wonders just how many centuries of VAX cpu time has been spent checking
- IOSBs over the past 15 years. Not to mention probing buffers, copying buffers,
- etc.)
