12. The interactive terminal as defined in claim 1, further comprising: H. keyboard encoder and control logic means communicating with said keyboard and said shift level control keys for generating a corresponding 6-bit binary word; I. transmitting means accepting the 6-bit binary word from said encoder and control logic means, incorporating means for adding a start bit and a stop bit to said binary word, and transmitting the resultant 8-bit binary word to the external data processing means; J. receiving means accepting an 8-bit binary word from the external data processing means, incorporating first means for masking the first and last bit of said binary word, and second means for transferring the 6-bit information portion of said word to memory in response to a memory transfer signal; and K. character address control means for determining available positions in said memory and incorporating second means for generating said memory transfer signal when the determination of available space in memory is made.
