A portable terminal executes instructions to perform processes including determining whether initial acquisition information is set, and determining whether designated device information is stored. The processes further include performing, when (1) it is determined that the initial acquisition information is set to the first value and (2) it is determined that the designated device is stored: receiving the operation identification information; updating the operation identification information; specifying the operation object; receiving a user operation of designating an object; and, when the user operation is received, preparing the designated device to execute an designated operation. The designated operation identified by the operation identification information corresponds to the designated operation object.
