This invention relates to a transmission terminal unit responsive to transfer instructions from a computer for serially transferring a plurality of information segments one at a time between successive locations within a region of a serial memory of the computer and an external system. The transmission terminal comprises buffer means for temporarily storing an information segment presently being transferred, means for serially transferring the information segments between said buffer means and the successive locations in the serial memory. Furthermore the transmission terminal comprises means responsive to the instructions from the computer for controlling the direction of transfer of the information segments by said transferring means and to signals from said computer and said external system for controlling the timing of the transfer by enabling, after the receipt of a ready signal from the external system, said transferring means to operate to transfer the next successive information segment when the location within the region of the serial memory which is next to be operated upon is available for transfers.
