Abstract
Abstract A communications system is provided in which at least the receiving terminal is a display terminal. The receiving terminal has the capability of storing substantially more data than just the data the alphanumeric representations of which is being displayed. The data receiving display terminal includes the text storage buffer for storing the received data. The text storage buffer has a capacity greater than just the data being displayed. The receiving terminal also includes apparatus operative during data transmission for displaying only part of the stored received data. The display terminal further includes expedients for selectively designating portions of the displayed received data and apparatus for printing such designated portions.
