PROBLEM TO BE SOLVED: To easily provide environment for an active communication abnormality processing test similar to real operation by providing the setting, storing and judging means of an error generating condition so as to generate isolated serial communication errors. SOLUTION: The setting, storing and decision means of an error generating condition are provided. Communication error equipment 17 consists of a pair of serial input/output devices (SIO) 13, 14, a CPU 15, an inputting device 16, etc. The equipment 17 is arranged between a pair of serial data communication equipments 11, 12, inputs serial data transmitted from both of the equipment 11, 12, and generates an error in the serial data sent from both of the equipments 11, 12, and generates an error in serial data in accordance with a set condition to output to the equipment 11, 12. The CPU 15 sets a communication condition to SIO, 13, 14 in accordance with a communicating condition set from the device 16. In this communication condition, in order to execute serial communication opposed to the equipment 11, 12, the communication condition of the SIO 13, 14 is equalized with that of the equipment 11, 12 to communicate with each other. |
