/* The central entry point for the emulator interrupt. This is used by

* Look at emuint.h for definitions and a list of the currently defined
* subfunctions.
* To call emuint from VM86 space do:
* push ax Save original ax value (*must be done* !)
* mov ah, funcnum Emuint function number to ah
* mov al, subfunc Subfunction number, optional, depening on func
* int 0xff
* ..
* ..
* Emuint saves the function and subfunction numbers internally, then
* pops ax off the stack and calls the function handler with the original
