Abstract
Existing voice telephone communications are augmented in a simple and understandable way by the addition of a "dumb" display terminal at a subscriber's location. Text, graphics, and picture data can be transmitted in ASCII code or other protocol, over existing, standard telephone lines and displayed on the terminal. The "dumb" feature is due to the display terminal having a voice/data selector that can automatically recognize digital data and switch from voice communication to data communication modes. Accordingly, this display terminal is entirely self contained and is controlled from a remote location, such as a telemarketing agents position, requiring nothing more from the subscriber than mere possession of the display terminal.
