Computer communication system

Abstract

Abstract PURPOSE:To realize an access to the data received from a computer of another end office in parallel with the key input processing, by using a communication control means which transmits and receives data and a key input control means which exchanges data between a transmission/reception buffer and a data file. CONSTITUTION:The signal received from an end office, e.g., a CPU A1 is converted into a signal having a frequency of a reception band by a frequency converter E connected to a transmission line D and can be received by each end office. A communication control means performs the transmission/reception of data between the transmission/reception buffers of each office as a background job. A key input control means decides the presence or absence of the reception data in the transmission/reception buffer while a computer is reading the key code data supplied from a keyboard. Then an access is given to a data file in a response to said reception data and the data are exchanged between the transmission/reception buffer and the data file.
