Telephone DTMF signal accessible data processor with calculator program
First Claim
1. A method of using a data processor having a telephone accessible application program, wherein said application program carries out functions in response to commands received from a telephone, comprising the steps of accessing said application program by telephone, sending a command from said telephone to said data processor to cause said data processor to switch from said application program into a calculator program which responds to commands received from a telephone to carry out mathematical operations, transmitting commands from said telephone to said data processor to cause said calculator program to carry out a mathematical calculation to determine a numerical result, then sending a command from said telephone to said data processor to switch said data processor from said calculator program to said application program, and using said numerical result in said application program.

Abstract
In a data processor having an application program accessible from a DTMF telephone, a calculator program is also provided. When a user has accessed the application program by means of a DTMF telephone, the user can switch to the calculator program to carry out a calculator function by means of a hot key input, in which the user presses the star key twice. Once in the calculator program, the user can enter numbers by pressing the telephone numerical keys and enter key sequences to command mathematical operations to be performed. The user can hot key back to the application program to continue the application program at any time by again entering the hot key transfer sequence in which the user presses the star key twice.
