1. A system for managing a port, comprising an interface that establishes a data-connection to the port, another interface that receives command-requests and stores command-messages in a buffer, and the interface periodically suspends the established data-connection with the port when command-messages are located in the buffer wherein the interface selectively sends command-messages from the buffer to the port and resumes the connection with the port within a prescribed time interval, wherein the prescribed time interval is determined by a heuristic calculation.
