Abstract
PURPOSE:To improve the efficiency of data transfer in a case where transfer data length in each information processor is different from each other, by deciding the optimum transfer data length in the information processor with each other by transmitting test data length when transferable data length is different. CONSTITUTION:A received response instruction is decided whether it is affirmation or negation by a managing part 12, and when a result is decided as the negation, no logical communication path is connected, and no data transfer is performed until a connection instruction is issued newly. When the response instruction is decided as affirmative response as a result, it is decided whether or not the data length assembled in a transmitted connection request instruction is equal to that assembled in the response instruction. And when the data length assembled in the response instruction is equal to the test data length, the managing part 12 decides the data length as the transfer data length, and delivers decided transfer data length and the response instruction to a connection control part 14.
