Subject: Must I Purge a TSR's HotKey from the DOS Keyboard Buffer?

	In an Interrupt 09h handler, I detect a Ctrl-Alt-x combination 
as a HotKey for a TSR  after first simulating an interrupt to the prior 
INT09 handler.

	Is something placed into the DOS keyboard buffer?

	If so, what exactly is placed there?

	Further, how do I purge the buffer of the HotKey so that other
software never sees it?	

	Also, if I hold the HotKey down for an extended time and cause
multiple enterings of the original INT09 handler due to key repeats 
before my new handler (for which I've prevented re-entry) finishes, 
the keyboard will fill up (assuming no buffer purging), will it not? 
What happens when it does fill up?

	Thanks.
