Abstract
A telephone device for accessing electronic services includes a housing having a front portion with a display device and a telephone keypad. The telephone device provides a graphical user interface whereby user selectable options are presented in a graphical format on the display device and a user is allowed to make selections therefrom with, for example, a point-and-click mechanism. A processor, preferably a single programmable digital signal processor, is responsive to the telephone keypad and the user selectable options and executes a variety of modem functions, telephone functions, and application programs. The programmable digital signal processor also supports the graphical user interface.
