Abstract
A method and apparatus implement a communications protocol whereby a host application program can communicate with a computer subsystem without the use of special driver software. In this way, the application program is able to invoke virtually any vendor-unique function on a compatible subsystem controller using only standard read/write system calls. This avoids platform dependency and greatly improves the portability of the application program.
