Data structure containing ponters to programmed I/O functions used by the

emulator. This is used so that the user program can hook all programmed

I/O for the emulator to handled as necessary by the user program. By
|

default the emulator contains simple functions that do not do access the
|

hardware in any way. To allow the emualtor access the hardware, you will
|

need to override the programmed I/O functions using the X86EMU_setupPioFuncs
|

function.
