A method and apparatus for a connection manager have been disclosed. By providing for persistent connections with clients, the connection manager allows for servers to communicate with clients, which would otherwise be inaccessible.

Method and apparatus for a client connection manager

A network comprising a server and a remote client including an input output pin is disclosed. The server and the client are connected through a Transmission Control Protocol (TCP) connection. The server controls the client input output pin, e.g., switches it on and off. The input output pin control instruction is transmitted from the server to the client. The control instruction is not stored in the client memory upon its execution.

Method and system to program programmable input output (PIO) pins via non-storage of a control message in a client

A single integrated circuit chip interfaces device control circuitry of a device to a client machine via a computer network. The chip comprises an internal data bus; a central processing unit connected to the internal data bus; an internal memory connected to the internal data bus; a device interface connected to the internal data bus, wherein the device interface comprises circuit blocks for communicating digital information between the integrated circuit and the device control circuitry; and a network interface connected to the internal data bus, wherein the network interface comprises circuit blocks for communicating digital information between the integrated circuit and the computer network. The internal memory comprises instructions for implementing complete internet protocol functionality on the network; translating information between network protocol formats and a format of the device; transferring information between the network and the device control circuitry; and sending customized software to the client machine over the network, wherein the software is executable on the client machine, and wherein the software enables the client machine to generate device control signals and to receive device status information. The single integrated circuit chip provides inexpensive, compact, powerful, and versatile interfacing of a large variety of devices to high performance computer networks.
