Filed: 1988-03-29
Abstract: PURPOSE:To prevent the abnormal end at the transmission side by executing the readout processing urgently if all of plural reception data buffers are occupied by the reception data and making a busy reception data buffer idle to attain the succeeding reception. CONSTITUTION:When the readout processing is executed and the transfer of a data of a relevant reception data buffer is finished to a host system 50, a communication controller control section 3 resets a bit corresponding to the operating state management flag. If there is no bit in off-state in existence in the operating state management flags, the communication controller control section 3 reports an emergent readout processing request to a host system control section 1 via an interrupt line 10 by interruption. The host system control section 1 stops tentatively a task under execution in response to the interruption at that time, executes the readout processing and restart the task stopped tentatively after the end of the readout processing. Thus, the abnormal end of data transmission from other external equipment is prevented.
