PURPOSE:To reduce the time for debugging and memory maintenance, etc., and the quantity of a memory by preparing processings whose connection systems are different from each other as the same program and executing a transfer processing of data. CONSTITUTION:A connection system deciding part 3 decides the designation of the connection system from a protocol processing module 1 and selects a connection system corresponding processing part 4. The selected processing part 4 saves information which is necessary when control is moved to a common processing part 2 and processes the connection corresponding to the connection system. Then, at the time of finishing the connection processing, the saved information is restored and the control is moved to the processing part 2 so that information without using a connection system is transferred. Thus, by preparing the processing having different connection systems as the same program, only the connection system may be added at the time of increasing a connection system and the time for the debugging and memory maintenance, etc., can be reduced. Besides, the quantity of the memory can be reduced, as well by putting the plural programs together into one.
