Abstract: To efficiently diagnose local and remote adapters without using dedicated hardware in a communication network to which a plurality of terminals are connected through associated adapters, a local logical address which is different from logical addresses reserved for communication between the terminals, is assigned to communication with a local adapter, and a frame including the local logical address and a diagnostic command is transmitted to the local adapter. When a remote adapter is to be diagnosed, a frame including a logical address assigned to communication with a remote terminal associated with that remote adapter, a diagnostic command, and at least one invalid character, is sent out from the local adapter to the network.
