  • Patent number: 6182204
    Abstract: In the CIS installation area of a PC card, the A region contains the basic attribute information of the card, the B region contains data of CIS1 for a modem, and the C region contains CIS2 for an ATA memory. The PC card is provided with a selection signal input means which selectively designates the CIS. A selection signal discriminator receives a signal from the selection signal input means and determines the selective designation of the CIS. When CIS1 and CIS2 are selectively designated together, a CIS switch setting element sets the start of the CIS read-in by a personal computer to the leading address of CIS1, and when CIS2 only is selectively designated, it switchably sets the start of the CIS read-in by the personal computer to the leading address of CIS2.

  • Patent number: 6085982
    Abstract: A PC card includes a plurality of functions and a plurality of CISs each for a single function or a combination of functions among the plurality of functions. A selection-signal input device inputs the CIS signal corresponding to the function to be used. A selection-signal determination section determines the designated CIS. According to the determination result, a CIS-switching setting section sets the designated CIS as the CIS to be read by a personal computer. A function-power-source switching control section supplies a power voltage only to the function corresponding to the designated CIS. An interface-bus-switching control section connects an interface bus for the function corresponding to the designated CIS to an interface bus connected to the main control section of the PC card.

  • Patent number: 6029211
    Abstract: A plurality of CIS1 through CISM are installed in memory of a PC card. Each CIS is provided with basic attribute information and functional attribute information, which are mutually independent, A selection signal for the CIS to be used is input from selection signal input means. A selection signal discriminator determines the CIS selected by means of the signal input from the selection signal input means. A CIS switch setting element sets the designated CIS as the CIS to be read in by a personal computer, and causes the CIS that has been set to be read in by the personal computer.

  • Patent number: 5673392
    Abstract: A method of executing communication programs in a modem apparatus. A plurality of communication programs used to perform data communication or facsimile communication are stored in an internal memory space (e.g., ROM) in a processor after they have been compressed. A communication program to be executed in ROM is decompressed and developed in a work area external to the processor (e.g., RAM). The developed communication program is then executed by the processor. The data decompression is performed according to an exclusive program decompression program or a program in the communication programs which is adapted to provide a data decompression function.
