A terminal device may supply a communication executing instruction to an OS program. The OS program may supply a signal sending instruction to a first wireless interface in response to obtaining the communication executing instruction, and the first wireless interface may start sending a polling signal in response to obtaining the signal sending instruction and establishes a first wireless connection with the communication device. The first wireless connection may be for causing the communication device to execute a specific process. After the first wireless connection has been established with the communication device, the terminal device may determine whether a predetermined condition is fulfilled; and in a case where it is determined that the predetermined condition is not fulfilled, may supply the communication executing instruction to the OS program without the specific instruction being inputted.
