I don't know if anyone else even cares about this feature, but I've used
it since the earliest days of MPE.

When you've started to type a command or a line of input, and realize
that you don't really want to send that line, you can, of course,
backspace over the entire line.  

But the right way to handle this is to type a CNTL-X (line cancel)
character.  The terminal driver puts out three exclamation marks and a
CR-LF, and ignores everything on that line.

Maybe everybody knows that, but I've run into a number of HP-3000 users
who aren't aware of it, especially in shops that use the Minisoft
terminal emulator.  Searching the archives, I found that this was
discussed about five years ago, but apparently Minisoft did not release
a fix.

Good news!  I brought this to their attention, and the current release
of the Minisoft 92 terminal emulator now handles CNTL-X.  I just thought
you would like to know.
