- 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.
