A method and apparatus for coding, transmitting, receiving, and displaying remotely or locally, all Arabic-Farsi characters or letters, basic arithmetic signs, numerals, punctuation marks and diacritical marks, as well as teleprinter operation commands in 5-bit standard Baudot codes. An Arabic-Farsi teleprinter similar in operation to the English teleprinter and compatible with the International exchange systems is provided without eliminating any letter forms. The teleprinter operation (the ability to compress the data into 5-bit characters) is based upon two basic criteria of the Arabic-Farsi languages, namely: (1) the form (start, middle, end or independent) of a character can be known if the preceding character and the following characters are known; and (2) there are six characters that are identical except for the presence or absence of a dot. The digital logic circuits make use of the above criteria to permit the encoding and decoding and thus the transmitting and receiving of complete Arabic-Farsi alphabets. A particular grouping of characters with level coder for each grouping, as well as a keyboard arrangement and control circuits for more versatile use of input/output devices are also disclosed.
