PURPOSE:To release automatically a system deadlock, by deciding the deadlock when a communication buffer is filled for a fixed time or longer. CONSTITUTION:A counter monitor part 4 always monitors the value of a transmitting buffer counter SBC0. When the counter SBC0 shows the value obtained when a buffer is filled, a set signal is transmitted to a timer part 5. While a reset signal is sent to the part 5 when the counter SBC0 shows a level lower than the above-mentioned value. In case the part 5 is set and no reset signal is produced from the part 4 for a fixed time set at the part 5, i.e., if the buffer is filled for a fixed time, an initial state setting part 6 is actuated by the output of the part 5. As a result, information processors 21-2n are initialized and a system initialized. |
