I have some code that does this sort of thing.  It was written by a co-worker
of mine.  It is a memory resident utility, that is smart enough to find any
copies of itself, and handles the chaining of several interrupts nicely.
Basically, it is written in assembly, and starts a process by stuffing
characters into the keyboard buffer, at a set time.  invoking it after
it is in memory, and passing a switch to it, causes it to travers the
interrupt chain, and change times, and /or change the keystroke buffer.
Give me a jingle
