Abstract
Abstract Dot matrix method of entering and transmitting script. For example, Chinese script in the form of a character or ideograph is written upon a dot matrix "keyboard", then registered and stored within a conventional computer memory. As desired, the computer may print the individual Chinese character or a plurality of Chinese characters, constituting the entire memory, upon a dot matrix printer. The present method is characterized by its capability of registering the entered script or character as digital information within a latch matrix, then transferring the digital information from the latch matrix as groups of bytes into an input/output control. The accepted digital information may be transmitted from input/output control to random access memory, read only memory, a microprocessor controller or external communications.
