<p>PURPOSE:To transfer data in the order smoothly by without increasing the load of the user of a line by informing a DTE of the state when the reception buffer of a DCE is fully occupied and storing the number of the DTE. CONSTITUTION:A microcomputer A controls an entire system and stores the number of a DCE whose reception is disable at the transmission and stores the information of reception disable to a memory C storing the number of an opposite party whose transmission is finished at the reception. Reception data are stored in a storage buffer F. An I/O device D interfaces a communication medium F such as a coaxial cable and the microcomputer A. The sequence timer G is used when the information of a reception disable state is received. The terminal equipment is connected to configure a network as shown in figure and acts like a DTE and a DCE. Even when plural DTEs and DCEs are connected to a data communication channel, the control at a fully occupied buffer is implemented smoothly without increasing the load of the line user.</p> |
