たものである。The present invention provides, in a host computer device connected to a terminal via a communication line, an address correspondence table in which terminal attributes are defined for each address range of the communication line, and addresses of messages received from the terminal are present in the terminal table. By creating a new terminal table using that address and the address correspondence table, even if a message is received from a terminal whose address is undefined, the communication between the terminal and the host computer that determines the terminal attributes can be maintained. This makes it possible to obtain optimal attributes and communicate even without the existing protocol.

端末の属性を知るための属性通知プロトコルがホストコ
ンピュータと端末間で必要である方式とがある。Conventionally, this type of terminal attribute determination method has an information area in which the address and terminal attributes are determined in advance for each terminal that attempts to perform data transfer with the host computer, and the information area defined by this network SG is One method communicates within the range of a terminal, the other has an information area where the attributes of undefined terminals are fixed in advance in consideration of connection requests from terminals with undefined addresses, and the other method has undefined addresses. It has an information area in consideration of connection requests from terminals, but the terminal attributes have not been determined.
There is a method that requires an attribute notification protocol between the host computer and the terminal to know the attributes of the terminal.

なるためそのプロトコルをサポートしていない端末とで
は端末属性が決定されない欠点がある。With the conventional terminal attribute determination method described above, when a new terminal is added, the address is undefined and communication is not possible, or even if communication is possible, the terminal attributes are fixed and the optimum attributes cannot be obtained. However, even if communication is possible, an attribute notification protocol is required to know the attributes of the terminal, so the terminal attributes cannot be determined with a terminal that does not support that protocol.
本発明はこのような欠点を除去するもので、ホストコン
ピュータと端末との間のプロトコル無しに最適な端末属

ことを特徴とする。The present invention provides a host computer device that is connected to a plurality of terminals via a communication line and includes a terminal table that stores addresses and terminal attributes corresponding to the plurality of terminals. If the address correspondence table with defined attributes and the address of the message received from the terminal are not in the terminal table,
The present invention is characterized by comprising terminal attribute determining means for creating a new terminal table using the address and the address correspondence table.

る。If the address of a message received from a terminal is not in the terminal table that stores addresses and terminal attributes corresponding to each terminal, terminal attributes are determined for each range of addresses and the addresses of each communication line. A new terminal table is created using the existing address correspondence table.
これにより、アドレスが未定義な端末から電文を受信し
