** It enabled terminals and 3705 communications processors to send " frames " of data one after the other without waiting for an acknowledgement of the previous frame-the communications cards had sufficient memory and processing capacity to " remember " the last 7 frames sent or received, request re-transmission of only those frames which contained errors that the error detection and correction codes could not repair, and slot the re-transmitted frames into the right place in the sequence before forwarding them to the next stage.
