PURPOSE:To confirm the past data having the high secrecy that are inputted and outputted through a communication circuit without using any special tool like a circuit monitor, etc., by registering the input/output history of data into a storage means. CONSTITUTION:The remote maintenance is carried out to an information processor 2 from a maintenance center system 4 or a fault occurs at the processor 2, and the contents of the fault of the processor 2 are transmitted to the system 4. Under such conditions, a maintenance diagnosis executing means 11 generates the data which are sent to the system 4. These data are sent to the system 4 by a communication control means 14 via a communication circuit 5. At the same time, the same data as those transmitted to the circuit 5 are also outputted to a data editing means 12. Thus a display means 3 can confirm the data. |
