Abstract
A portable, hand-held data telecommunications terminal for use with a telephone system having a memory for storing data, a signal generator for generating signals corresponding to the data, a signal coupling device connected to the signal generator for coupling the signals to the telephone system, a keyboard, a microprocessor, and a self-contained power supply. The microprocessor is connected to the memory, the signal generator and the keyboard device so as to control, under the direction of the keyboard, the receipt of data from the keyboard, the storage of the data by the memory, and the generation of the signals by the signal generator. Data is entered into the memory from the keyboard device so that the data is available at a future time, to be coupled to the telephone system.
