Recovery apparatus and control method of resource recovery apparatus

An information processing apparatus generates a command for a communication terminal apparatus and a retry command and successively outputs the generated command and retry command to an information processing terminal apparatus. The information processing terminal apparatus acquires the command for the communication terminal apparatus and the retry command that have successively been output from the information processing apparatus and outputs the acquired command to the communication terminal apparatus. Further, in a case of performing a retry process due to unavailability of a response to the command, the information processing terminal apparatus outputs the acquired retry command to the communication terminal apparatus. The retry process can be performed without waiting for the information processing terminal apparatus to output a command request to the information processing apparatus and acquire a retry command. Accordingly, a process between a communication terminal apparatus and an information processing apparatus via an information processing terminal apparatus can be performed efficiently.
