PROBLEM TO BE SOLVED: To easily monitor the communication data of an exclusive terminal. SOLUTION: When a command is inputted by operating an operating part 10 for monitoring a network, a control signal is outputted through a bus 8 for a control signal to an infrared communication, control part 7 and the infrared communication control part 7 performs infrared communication with an infrared communication control part 5. At such a time, when a response from the opposite side can be provided, input/output data are transmitted from a network control part 3 through a bus 6 for data to the infrared communication control part 5 and the communication data of the exclusive terminal are displayed on a display part 12. In the case where the response from the opposite side can not be provided even after the command is transmitted three times, the line is disconnected. |
