Abstract: A communication protocol available to any type module on the computer bus. Application programs are treated as clients or servers. A serveport is created in the server module. A client issues a connect request to the server identifying the serveport. The server assigns a N-slot TID capability to identify, describe and protect a storage location for receiving a start buffer from the client and sends the N-slot TID to the client to establish a connection. The start buffer includes a TID list which permits the client and server to reliably communicate back and forth. Once a connection has been established, data can be moved between the server and the client. High-level instructions and commands are sent as data through these connections. After the communication has been completed, the connection can be disconnected by the client or broken by the server.
