    Description

      (as a placeholder - needs to find a software that does not suffer from the lack of PIT synchronization limits in current ntvdm)

      It requires https://www.highrez.co.uk/downloads/inpout32/ - install the driver via InstallDriver.exe and copy inpout32.dll on the system directory.

      inpout32.dll is loaded dinamically (the bundled .lib has method bundled - the inpout32.dll has cdecl functions prototypes but they are really stdcall functions - forcing to link them in cdecl causes the function return goes hayware due to the different calling convention)

      Similarly it could be used for serial COM1 communication or other I/O ports.
