the author of this app says:

PocketDOS is a powerful virtual PC software environment for your pocket computer that allows you to run a DOS operating system and have instant access to many DOS applications on your pocket computer, whilst simultaneously allowing the use of the pocket computer's native applications. PocketDOS also allows DOS applications to access serial ports, built-in modems, infrared ports, bluetooth devices, removable storage disks, touchscreens and shared network resources, and allows file sharing between the pocket computer's native applications and DOS applications.
