Control device and control method

Abstract

A control device includes a first processor, a relay device, a second processor, and a third processor. The first processor is configured to perform data communications with an electronic device. The relay device is configured to relay the data communications. The relay device includes a buffer for storing data to be transmitted or received in the data communications. The second processor is configured to check a state of the buffer to detect a buffer full state in which the buffer is full. The third processor is configured to check a state of the first processor to detect a halt state in which the first processor has halted. The third processor is configured to reset the relay device upon detecting the halt state and upon the second processor detecting the buffer full state.
