It has been proposed that when a network is monitored to detect a message addressed to a client device in the sleep mode, the server makes a proxy response based on information stored in advance by the server. In this case, the sleep mode of the client device is continued until a message other than the content stored in advance is detected by the server and an instruction to return to the normal mode is output to the client device. Useless return is prevented.
- each of the network-compatible devices is capable of reducing the content of the externally received signal even in the power saving mode.

Sent to response Hap 1 (corresponding to S12 and SI3 in Fig. 3).
- the proxy response hub 2 detects the reception of the sleep notification d 11 addressed to itself and the notification d 12 of the internal information (corresponding to the Y side of S 32), the proxy response hub 2 thereafter performs Then, a predetermined response process is performed on behalf of the printing device 2 in the sleep mode. That is, when communication data including the internal information request command d 13 is received from the host device 3 with the printing device 2 in the sleep mode as a destination, the internal information request command d 13 Is transmitted from the proxy response hub 1 to the host device 3 that is the transmission source of the internal information request command (corresponding to S46 in FIG. 2).
- the printing in the sleep mode from the host device 3 is performed.
- the print data d 21 addressed to the device 2 that is, communication data not including the internal information request command d 13
- the print data d 21 is sent to the printing device 2 addressed to the print data d 21.

- the printing apparatus 2 performs the normal processing in the normal mode. Therefore, even if the internal information request command d 13 is transmitted from the host device 3, it is transmitted (transferred) to the printing device 2 as it is via the proxy response hub 1, and The internal information notification d14 corresponding to the internal information request command d13 is returned.
- the internal information request command is common to all the communication ports 11 1 to 11 11, but, for example, the internal information request command and the corresponding The internal information may be stored for each communication port. Accordingly, even when different types of network compatible devices are connected to the respective communication ports, it is possible to make a response according to each network compatible device.
- the proxy response hap 1 is configured to perform a proxy response only for a network-compatible device connected to a predetermined part of the communication ports lll to lln. Thereby, the capacity of the storage unit 12 can be reduced.
- the concentrator when a plurality of network-compatible devices (for example, the printing device 2 and the like) are connected via a concentrator to form a star network, the concentrator can save power. Instead of the network compatible device in the sleep mode, a proxy response is made to the inquiry from another device, so that the network compatible device can be prevented from returning from the power saving mode to the normal mode unnecessarily. . Furthermore, since each network-compatible device does not need to determine the content of the received signal during the power saving mode, it is sufficient to operate a simple circuit or the like for detecting the presence or absence of a signal reception. Power consumption in the power saving mode can be reduced as much as possible. In addition, a proxy response of a plurality of network compatible devices can be performed by one concentrator, so that a power saving effect proportional to the number of network compatible devices connected to one concentrator can be obtained. .
- a proxy response is made by the concentrator to which the network-compatible device is connected, as in the case of performing a proxy response with a predetermined server, it will not operate properly unless the connection position of each device to the network is considered. There are no restrictions.
