Abstract
PURPOSE: To prevent the error recognition of the terminal that the center can not be used by automatically responding to the terminal by the communication control device in case there is generated temporarily the response delay in the central portion.
CONSTITUTION: The circuit corresponding portion 1 for carrying out the receipt or transmission of the data to the circuit or disassembling and asembling of the character is connected to a control processing portion 2 for integrating and controlling the whole device and a response processing portion 3 for producing a response to the terminal. The processing portion 2 is connected to the processing portion 3 and the channel processing portion 4 for carrying out the control in receipt and transmission of data to CPU. The initiation from the terminal is transmitted to the processing portion 2 by the signal A, while in the processing portion 3, in case the command E does not come within a predetermined time T after the command D is received during CPU performs another processing, the signal C is generated in order to carry out the judgement of non-response by the terminal and C is transmitted as the response signal ACK through the circuit processing portion 1 to maintain the connecting condition with the terminal.
