Provided is a data processing apparatus including: a storage unit that stores a first operating system (OS), a first application program executed after the first OS, a second OS, and a second application program executed after the second OS; and at least one processor configured to, in a first activation mode, verify the first OS, execute the first OS, and then execute the first application program, and, in a second activation mode, verify the second OS, execute the second OS, and then execute the second application program, in which the at least one processor is further configured to restore the first OS, in a case where it is determined on the verification of the first OS that the first OS is not valid, with use of the second OS.

In accordance with an authenticated user designating a destination linked to self as a transmission destination, the transmission destination is set, and a transmission setting including the set transmission destination is registered together with first information indicating that the transmission destination was designated by designation of the destination linked to self. Also, in a case where another user is authenticated, and in accordance with a read instruction for the registered transmission setting, the transmission setting that is the target of the read instruction was registered together with the first information, as a transmission destination of the transmission setting a destination linked to the another user, who performed the read instruction, is set.

A multifunction device integrally includes a first device and a second device. The first device has a first system, and the second system has a second system. The second device requests, in response to a predetermined command entered, a first snapshot of the first device from the first device. The first device generates the first snapshot in response to a request from the second device, and sends the first snapshot to the second device. The second device generates a second snapshot of the second device in response to the predetermined command entered, and saves, to a save destination, the first snapshot sent and the second snapshot. The first device starts the first system by using the first snapshot saved in the save destination. The second device starts the second system by using the second snapshot saved in the save destination.

An information processing apparatus configured to control wireless communication by receiving user input of a start instruction to start a cooperation operation, the cooperation operation configured to cause a first apparatus to transmit target data to the information processing apparatus. The information processing apparatus wirelessly receives the target data from the first apparatus through a first access point by using the wireless communication interface after receiving the start instruction, and terminates wireless communication with the first access point. Once wireless communication with the first access point is terminated, the information processing apparatus may establish wireless communication with a second access point through which the information processing apparatus is communicable with a second apparatus, and wirelessly transmit the target data to the second apparatus through the second access point.

Examples to facilitate facsimile communication are described herein. In an example, on receiving a communication error for a call session, values of communication parameters to be used for another call session, which is subsequent to the call session for which the communication error is received, may be determined. The communication parameter may be, for instance, a transmission rate and an error correction mode (ECM). The values of the communication parameters in the subsequent call session may be determined, based on values of these parameters in a previous call session(s), i.e., the call session for which the communication error is received. Further, a communication channel may be established using the determined values of the communication parameters.

In accordance with an authenticated user designating a destination linked to self as a transmission destination, the transmission destination is set, and a transmission setting including the set transmission destination is registered together with first information indicating that the transmission destination was designated by designation of the destination linked to self. Also, in a case where another user is authenticated, and in accordance with a read instruction for the registered transmission setting, the transmission setting that is the target of the read instruction was registered together with the first information, as a transmission destination of the transmission setting a destination linked to the another user, who performed the read instruction, is set.

Provided is a method of generating a workform that defines an order of performing jobs, the method including: setting any one of an image forming apparatus and a mobile device as an input source for receiving a job target; setting a transforming method for transforming a job target received through the input source; setting any one of the image forming apparatus and the mobile device as a transmission destination for transmitting the job target transformed according to the transforming method; and storing a workform defining an order of performing jobs according to the input source, the transforming method, and the transmission destination.

A communication device includes: a signal reception circuit to receive a differential signal and convert the differential signal into binary data; a squelch detection circuit to compare an amplitude level of the differential signal with threshold voltages to detect presence or absence of a signal and detect a non-squelch state and a squelch state; a start pattern detection circuit to enter a receivable state in response to a predetermined start pattern based on the differential signal; a register that stores a squelch setting value associated with the threshold voltages; a DC voltage selection circuit to select two DC voltages in accordance with the squelch setting value, and supply the two DC voltages to the squelch detection circuit; and a squelch setting control circuit to change the squelch setting value to increase or decrease the squelch setting value in steps and sequentially set the squelch setting value in the register.
