Automatic SendingUsing start-stop equipment, the operator may "type" the message directly "onto the line" or the operator may record the message as perforations in a paper tape (Table I). This perforated tape, when fed into an automatic transmitter, sends the telegraph message to the distant station. Several possibilities exist: first, the tape may feed directly from the tape perforating equipment to the automatic transmitting equipment; and second, operators may perforate tape at their convenience, and then the recorded messages may be transmitted continuously.
