This is an updated version of Daniel Dorau's Aspi Router device driver. It is designed to support simultaneous access to the driver from more than 1 process (currently limited to 4 in this Beta version). For the programmer, it simplifies and enhances the interface whilst retaining backwards compatibilty and removes the need for application semaphores to signal command completion.
