    摘要: A data communication system, capable of operating in an error correction mode, is capable of producing, when data received in an error correction mode could not be correctly recorded, information indicative of the occurrence of such a recording failure. When an error exists in data received in the error correction mode, a message is recorded subsequent to the recording of the received data to announce the presence of the error, thus facilitating recognition of the occurrence of error.

    摘要: A data communication method includes the steps of: sending a communication procedure signal prior to data communication; sending a data signal; and sending a stop signal for stopping an echo suppressor function on a communication network; wherein the stop signal is sent prior to the data signal in such a way that a time interval during which no signal is generated does not occur, after the stop signal is sent, until the data signal is sent. A data communication apparatus includes: a communication unit for sending and receiving a data signal; a discrimination unit for discriminating if the apparatus is a calling station; and a control unit for controlling to change a communication controlling mode based on the output from the discrimination unit.

    摘要: There is a data communication apparatus having a transmitting section to divide data into a plurality of units and transmit the data and a memory section to store the data. This apparatus reads out the data of the designated unit from the memory section in response to a retransmission request signal from the reception side and a signal indicative of the designated unit and then retransmits the readout data from the transmitting section. Thus, even if the transmission error occurs the data can be retransmitted from the corresponding line and the retransmission is efficiently executed.

    摘要: A multi-function apparatus having a wider variety of uses and easily employed when carrying a USB cable only without having a power source cord. The apparatus includes means for detecting a connection between the USB interface and the PC, means for detecting a connection to the power line, and control means for selecting a function depending on a detected state of the connection between the USB interface and PC and a detected state of the connection to the AC power line. All the functions in the multi-function apparatus are operable in a connected state of the AC power line to the AC power source, while even in an unconnected state of the AC power line to the AC power source, if the USB interface is connected to the PC, a possible operation is enabled using electric power of 5 V at 500 mA supplied from the PC.
