ABSTRACT:
A data communication apparatus as a device. A discrimination data of own device is sent. When the discrimination data is received from another device, the discrimination data is stored as a direct communicatable device for the own device. A direct communicatable device list including the stored discrimination data is generated and sent with the discrimination data of the own device. When the direct communicatable device list is received from other device, the direct communicatable device list is stored as an indirect communicatable device for the own device. In response to selection of the discrimination data as a destination address from the discrimination data of the direct communicatable device and the indirect communicatable device, data with the destination address is sent. When the data is received from other device, the destination address of the received data is decided to coincide with the discrimination data of the own device or the direct communicatable device. If the destination address coincides with the discrimination data of the direct communicatable device, the received data is relayed to the direct communicatable device of the destination address.
