ABSTRACT:
Disclosed is an extension device for use with a computer system which includes a memory for storing an application program which can perform at least one software function. A modem is operative to encode the at least one software function to first tone signals and transfer the first tone signals onto a telephone line. The modem is further operative to decode second tone signals received from the telephone line and transfer the first tone signals in response thereto. The second tone signals are operative to control the at least one software function. The extension device includes a user operable keypad for inputting command signals corresponding to the at least one software function. A display is included on the extension device for displaying information related to the at least one software function. The extension device also includes a controller which is coupled to and controls the keypad, display, a signal generator and a signal decoder. The controller and signal generator are operative to convert the command signals to the second tone signals. The controller and signal decoder are operative to decode the first tone signals to control the extension device to operate in accordance with the at least one software function.
