  • Patent number: 5737540
    Abstract: In a data communication system, a plurality of personal computers are connected through respective terminal adapters to a telephone line. Each terminal adapter includes a communication control section, a storage section and a network control unit (NCU). The communication control section includes a central processing unit (CPU), a read only memory (ROM) and a modulator-demodulator or modem. The terminal adapter has a power supply independent of a power supply of the personal computer so that power can be applied to the terminal adapter even when the personal computer is not connected to the power supply. The terminal adapter can automatically receive a mail regardless of the status of the personal computer. The received mail is stored in the storage section of the terminal adapter. When a recipient reads the received mail, the personal computer is started up and a key board connected to the personal computer is operated in accordance with a menu.

  • Patent number: 5568164
    Abstract: A cursor display system causes a cursor to move on a screen in the same direction as that of a pointing device, such as a mouse, operated by an operator viewing the screen, even if the display on the screen is inverted, i.e. turned round through 180 degrees. To display the cursor, which is moved by operating the pointing device, on a display device which is capable of inverting the display on the screen, a display status holding device is provided for memorizing whether the screen displayed on the display device is in a normal status or in the inverted status. The display status holding device is connected to a changeover device for changing data of operating directions supplied from the pointing device depending on the status memorized by the display status holding device.
