Then, when a reply confirmation “required” is received, if the reception is wireless reception, a reply is made by FAX, and if the reception is FAX reception, a reply is made wirelessly. Then, control is performed by the personal computer 14 or the line connection control device 12 of the terminal station 2 (S31). At that time, if reception by transmission type (wireless or FAX) is received for each received command NO, information indicating “reception OK” is returned (S32).
The control station 1 receives this reply confirmation (S33), and resets the reply confirmation flag D45 in the command information memory table (that is, reply confirmation “OK”) (S34). In this case, when the command protocol D42 is “simultaneous command”, the reply confirmation flag D45 is reset by receiving the reply confirmation “OK” from all the terminal stations 2 that are the targets of the simultaneous command. The Rukoto.

If the reply confirmation flag D45 is not reset, that is, if the reply confirmation is NG, or if a reply from the terminal station 2 is not received even after a predetermined time has elapsed after the transmission of the command, the terminal or NG Retransmission is individually performed to the terminal that has become (S41).
