ABSTRACT:
A data transfer system has a PC as a host computer, a terminal unit such as a printer and a parallel interface cable through which data is transferred between the PC and the terminal unit. The PC transfers a strobe signal as a rate detection signal which contains points of change to the terminal unit. The terminal unit receives the strobe signal and calculates the data processing rate of the PC on the basis of the points of change of the strobe signal. The PC adjusts the data transfer rate of the PC on the basis of a result of comparison of the data processing rate of the PC calculated by the terminal unit and a processing rate of the terminal unit.
