	Greetings netters,
		I have a need to write a program for MSDOS that will act
		as a TSR to redirect IO manipulation by another program
		to my own custom hardware. That is to say:

		1. Trap any IO reads/writes to a specific port
		2. Simulate Interrupts from hardware

		This is somewhat like writing a debugger that allows traps
		whenever low level IO is accessed.
		Needless to say this must all be done in software.
		The software can be specified to only run on 386 class PC's.

		Does anyone have experience in writing this kind of software?
		Are there any books which might discuss this kind of hardware
		simulation?

		I will post a summary of any email if there is interest.
