communications A term applied by Western Union Telegraph
Company to teletypewriters that are not part of a
multiplex system. They usually provided for alternate
transmission in both directions. If working simplex or
half-duplex, what was keyed in at the keyboard would be
typed out at the printing portion. If working full-duplex,
sending would be blind as the printing portion was being used
only for reception.
