Hi,
A TSR is a Terminate and Stay Rsident Program.One of the standard example of
the
TSR is teh doskey .What happens is that when ever u press a key on the
keyboard
then an interrupt is generated and the appropraite ISR (interrrupt service
routine) is  called
which  takes  care of the handling of the key pressed  in the keyboard.What
happens is that
in  MSDOS is that the doskey TSR sits instead of the ISR and stores the keys
pressed in the buffer until a enter key is pressed and also calls the normal
ISR for each key pressed.
Coming to  TSR'sthey have become extinct as windows doesn't allow u to
modify
the ISR etc.The DOS that u r running on windows is not the real one but a
simulated
one and so is the doskey Program.In Linux u r not allowed to access the ISR
and hence
the prospect of TSR's become impossible.If it is allowed it may lead to a
security  bug
may be.
Thanx,
Harishankkar.S
