Abstract

PURPOSE:To facilitate the build-up of a job system of a computer by connecting an external equipment of a data communication section of the computer to a communication line via an independent equipment for high-speed unidirectional synchrornizing communication reception so as to relieve the load rate on a CPU. CONSTITUTION:The titled equipment consists of a serial synchronizing communication control section 4 being a communication equipment installed to the input side of the computer receiving unidirectional and random serial synchronizing data, two data buffer sections 5 analyzing the serial reception data and storing them in the unit of a prescribed word length, a data buffer control section 6 switching the data to other data buffer 5 if the data buffer 5 is occupied during reception, in case of reception timeout or the remaining data buffer capacity is not enough for the maximum received text length and a parallel data transfer control section 7 transferring the data of the data buffer section 5 finished for reception in the DMA transfer to the computer. The communication interface is connected to the line via the independent unidirectional synchronizing communication equipment of the computer to relieve the load attended with the reception processing of the computer.
