Hi,

The DosBox's docs are telling that the IOCTL API is implemented ("almost"). So I was curious and loaded an external EMM (Jemm386, which can be loaded from the command line) into DosBox. It loaded without errors and the cpu was in v86-mode then, but all attempts to communicate with the "EMMXXXX0" device failed (this is/was sort of a standard to talk to the EMM from real-mode ). Doesn't DosBox scan the list of installed devices if "someone" wants to open a file/device?
