A telephone device (100) that enables a user to perform data processing functions. Data processing functions include calculator, recorder, data transmission, facsimile, and answering device functions. A macro function is further provided to enable an invocable sequence of telephone buttons (104) to be defined by the user. Telephone calls can be received and processed (112) while the telephone device is in an off-line mode.
