<P>PROBLEM TO BE SOLVED: To transmit a model-dependent character as it is to a receiving-side client terminal in a specific environment without a user's recognition for that the model-dependent character is a model-dependent character not usable between transmitting-side and receiving-side client terminals in a general environment. <P>SOLUTION: The data communication network system comprises a model-dependent character determination means which receives, when transmitting data from the transmitting-side client device 1 to the receiving-side client devices 2 and 3 in reference to a database, the data prior to the transmission thereof to the receiving-side client devices, and checks whether a model-dependent character of the transmitting-side client device is contained therein or not; a model-dependent character interchangeability determination means which determines, whether the model-dependent character is contained in reference to the database, whether the model-dependent character is compatible between the transmitting-side client device and the receiving-side client devices or not; and a predetermined processing means which performs, when the character is determined to be compatible in reference to the database, communication processing to a communication line without converting the model-dependent character. <P>COPYRIGHT: (C)2009,JPO&INPIT |
