Abstract
A LAN system comprises LAN controllers provided for computer systems that constitute a multi-computer system. Each LAN controller has a memory section in which a LAN address common to the multi-computer system is set in accordance with a command from a master computer of the computer systems, and a register section for holding a reception permit command (flag) from the master computer system. Only when the reception permit command is held in the register section, a transmission frame whose destination address is the LAN address held in the memory section is selectively received from a LAN and transferred to the master computer system.
