The simulate_keypress() function adds an entry to the Allegro
keyboard buffer, but this has nothing to do with the win95
input handling mechanism. I'm not aware of any way for a DOS
program to fake keypresses that far up the chain, because 
win95 processes these events many levels higher than anything
that your program has access to. There may be some special
API functions that you can use to minimise your program (look
in the Interrupt List), but I have no experience of that.
