Abstract:
A modem apparatus comprising:a modem circuit, operatively connected to a control unit external to the modem apparatus and a communication line, for modulating a carrier signal so as to generate a modulated signal according to signal data inputted from said control unit and transmitting the modulated signal through said communication line, and for demodulating a modulated signal received through said communication line so as to generate a signal data and outputting the signal data to said control unit;first storage means for storing a communication program to be executed by said control unit;second storage means for storing a telephone number list data including a plurality of telephone numbers of further parties which are used when the communication program is executed;interface means for connecting said first storage means, said second storage means and said modem circuit to said control unit, and executing an interfacing process between said control unit and each of said first storage means, said second storage means and said modem circuit, wherein the first storage means and the second storage means are separate from a ROM and a RAM located in the modem apparatus; andthird storage means for storing an initial operation program of said control unit for directly accessing said first and second storage means of said modem apparatus, executing the communication program stored in said first storage means, and reading out the telephone number list data from said second storage means,wherein said interface means connects said first storage means, said second storage means, said third storage means and said modern circuit, to said control unit, and executes an interfacing process between said control unit and each of said first storage means, said second storage means, said third storage means and said modem circuit.
