Abstract
A frame transmission method for a terminal having system control unit, a reader, a recorder, an operator interface unit, and a communication control unit. The system control unit includes a line memory, which is connected to the reader and the recorder, and a buffer memory, which is connected to a flow buffer provided in the communication control unit, which, in turn, is connected to a transmission line or network. Thus, buffering in transmission of data is provided between the line memory and the buffer memory and also between the buffer memory and the flow buffer. With this structure, the data is transferred to the transmission line in frame format, and the frame transmission condition is varied by detecting the speed of production of data to be transmitted and/or the empty condition of the transmission line depending on the amount of the data to be transmitted accumulated in the flow buffer so as to optimize the transmission efficiency.
