I could have sworn that I just saw something like this
posted on Freshmeat a few weeks ago. It seemed like
it was basically like this (or like the old FAKEY.COM
program for Messy-DOS).
It might be fun to wrap this function with a
command line parser and a --help message and post it
to [fm].
There was one Messy-DOS utility that a friend of mine
wrote as a throwaway. This one was for quality
assurance. It was different because it would somehow
reprogram the keyboard controller (not the 8042 on the
motherboard but the 80xx inside the keyboard itself)
and force it to send the keystrokes back after a short
programmed delay. This allowed him to guarantee that
there was NO TSR present when the software to be tested
was loaded.
(If we really wanted something like that for Linux
I'd suggest a device driver. If I really needed something
like that for my own QA buy a serial to keyboard converter
out of the back of Circuit Cellar Ink and use a second
computer to feed the keystrokes into the target port).
