Abstract: A function executing device may be configured to receive a related instruction related to execution of a scan from an external device, and in a case where the related instruction is received from the external device via a first communication path for executing an encrypted communication, send an authentication information request to the external device. In a case where the related instruction is received from the external device via a second communication path for executing an unencrypted communication, the function executing device may be configured not to send the authentication information request to the external device.

Abstract: A reading system includes a terminal device including a first controller and a storage, and a reading device including a second controller, the reading device being connected to the terminal device and configured to read an object to be read. The storage is configured to store a first program, a second program, and a third program, the first program being an application program corresponding to the reading device, the second program being a general-purpose driver application called from the first program, the third program being a predetermined application program different from the first program and the second program. The second program includes a first mode in which a user interface of the second program is used, and a second mode in which an other user interface that is not the user interface of the second program is used.

Abstract: A reading apparatus includes a user interface, a scanner, and a controller configured to perform a push scan that causes the scanner to read a document according to an execution instruction corresponding to an operation on the user interface, and a pull scan that causes the scanner to read the document according to an execution instruction from an external device. The controller is configured to set a restriction setting value relating to a restriction on the push scan, and in a case where the controller receives an execution instruction of the push scan via the user interface, restrict the push scan according to the restriction setting value. In a case where the controller receives an execution instruction of the pull scan, the controller is configured to specify whether authentication is necessary with respect to the execution instruction of the push scan, based on the restriction setting value.

Abstract: There is provided a reading apparatus including: a user interface; a communication interface; a scanner; and a controller configured to execute a first scan in response to an instruction to execute the first scan based on an operation to the user interface, and a second scan based on an instruction to execute the second scan from an external apparatus connected to the reading apparatus via the communication interface. The controller is configured to: execute the first scan without requiring authentication in a case where the controller receives, via the user interface, the instruction to execute the first scan; and perform the authentication in a case where the controller receives, via the communication interface, the instruction to execute the second scan, and then execute the second scan in a case where the authentication succeeds and not execute the second scan in a case where the authentication fails.

Abstract: A communication apparatus can perform an appropriate process in response to a job notification received from a server. The communication apparatus sets an operation mode to a first mode. The first mode is a mode to receive a job notification from a server using a connection established for server-push communication between the communication apparatus and the server. The job notification indicates whether a job to be performed by the communication apparatus is occurring. The communication apparatus disconnects the connection before completion of a first job in response to a first job notification being received from the server using the connection during the first mode. The first job notification indicates occurrence of the first job to be performed by the communication apparatus. The communication apparatus performs the first job in response to the first job notification being received from the server.

Abstract: A communication device may set an operation mode of the communication device to a first mode, the first mode being for repeatedly sending a polling signal to a specific server on the Internet so as to receive target data from the specific server. The communication device may receive a response including related information which is related to the target data from the specific server, and receive a response not including the related information from the specific server. The communication device may set the operation mode of the communication device to a second mode instead of the first mode in a case where a first predetermined condition is satisfied in a state where the operation mode of the communication device is the first mode, wherein the second mode is for receiving the target data from the specific server without sending the polling signal to the specific server.

Abstract: A communication device may determine whether the communication device is in a proxy environment or in a non-proxy environment. The communication device may set an operation mode of the communication device to a first mode in a case where it is determined that the communication device is in the proxy environment, the first mode being for repeatedly sending a polling signal to the specific server so as to receive target data from the specific server. The communication device may set the operation mode of the communication device to a second mode in a case where it is determined that the communication device is in the non-proxy environment, the second mode being for receiving the target data from the specific server without sending the polling signal to the specific server.

Abstract: A management device transmits to a target device a first GETNEXT request comprising a first group of Ma-combined IDs. Each combined ID is a combination of a target ID and one of Ma-index values. Each index value has a first value in its highest digit(s) and one of consecutive values in its lowest digit. The management device obtains Ma-partial information and a second group of an Ma-combined IDs corresponding to the Ma-partial information, identifies a greatest combined ID having a greatest index value from the second group, and transmits a second GETNEXT request comprising Mb-combined IDs comprising the identified greatest combined ID. Each combined ID is a combination of the target ID and one of Mb-index values. Each index value has a second value different from the second value in its highest digit(s) and one of consecutive values in its lowest digit.

Abstract: A management device may determine, with reference to a table, whether target information to be obtained, from a target device, corresponding to a target ID is index information. The management device may transmit a first main request including Ma-combined IDs to the target device when the target information is the index information. Each of the Ma- combined IDs may be a combination of the target ID and one of Ma- consecutive index values. The management device may determine whether Ma- partial target information corresponding to the Ma- combined IDs cannot be obtained. When the Ma-partial target information cannot be obtained, the management device may transmit a sub-request to the target device. The sub-request may comprise N- combined IDs forming a subset of the Ma- combined IDs in the first main request. N may be an integer that is 1 or greater and may be smaller than Ma.
