DEVICE SERVER SIMULTANEOUSLY COMMUNICABLE WITH MULTIPLE CLIENTS

PROBLEM TO BE SOLVED: To simultaneously use a device connected to a device server from a plurality of client PCs, in a device server system.SOLUTION: In a device server system in which a device performs unidirectional communication to a client PC, the device server stores information (initial information) at the time when the client PC and the device are connected. When a connection request from another client PC is received, communication with the device is not performed and the stored initial information is returned. By this way, the other client PC can perform pseudo-connection with the device and can receive data from the device.
