Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
178 words
A computer, comprising: process means for effecting a data process; means for effecting data communication through a communication line; means for effecting voice message communication through the communication line; means for detecting a request for communication from the communication line; a memory storing both a program from controlling said process means and a program for controlling said data communication means and said voice message communication means; control means for controlling said process means, and said data communication means and said voice message communication means in accordance with the programs of said memory, wherein said control means executes said data and voice message communication means controlling program in response to a detection signal from said detection means, and wherein upon receipt of the detection signal from said detection means during the execution of the process means controlling program, said control means alternately executes the process means controlling program and the data and voice message communication means controlling program so that said process means controlling program and said data and voice message communication means controlling program are executed in parallel.
Claim 2
Dependent Claim
178 words
A computer, comprising: process means for effecting a data process; means for effecting data communication through a communication line; means for effecting voice message communication through the communication line; means for detecting a request for communication from the communication line; a memory storing both a program from controlling said process means and a program for controlling said data communication means and said voice message communication means; control means for controlling said process means, and said data communication means and said voice message communication means in accordance with the programs of said memory, wherein said control means executes said data and voice message communication means controlling program in response to a detection signal from said detection means, and wherein upon receipt of the detection signal from said detection means during the execution of the process means controlling program, said control means alternately executes the process means controlling program and the data and voice message communication means controlling program so that said process means controlling program and said data and voice message communication means controlling program are executed in parallel.
