Emulating system for developing a home network

PURPOSE: An emulating device for developing a home network is provided to verify whether data transmitted/received between a home server and a client computer corresponds to a CIM format and whether the data has an error. CONSTITUTION: A packet receiver(211) receives a packet including certain data by using serial communication from a home server or a client computer. A packet verifier(212) verifies whether the packet has a CIM format, and if the packet has the CIM format, the packet verifier(212) checks whether the data has an error. A data extracting unit(213) extracts data from a packet which is verified to have the CIM format, does not have an error and has not been repeatedly received. A packet transmitter(214) transmits the packet, received from the packet receiver(211), which has the CIM format and does not have an error. A display unit(215) displays the packet or the data.
