Abstract: A communication device may include a first type of interface and a second type of interface. The communication device may execute the communication of object data with a mobile device using the second type of interface after executing a specific process for causing the communication device to shift to a communication-enabled state, in a case where it is determined that the communication device is not currently in the communication-enabled state. Also, the communication device may execute the communication of the object data with the mobile device using the second type of interface without executing the specific process, in a case where it is determined that the communication device is currently in the communication-enabled state.

Abstract: A communication device may include: a memory configured to store management information in which, for each of a plurality of OIDs of a MIB, the OID and a setting value are associated with each other; and a controller, wherein the controller may be configured to: receive a setting command which conforms to TCP; write the setting value included in the setting command to the management information in association with the OID included in the setting command; and send a response command which conforms to the TCP.
