His modification consisted of a paper tape reader from a teletype machine attached to a small device with metal " feelers " positioned to pass electricity through the holes.

If a library routine fails for some reason unrelated to a system call ( for example, because a user name wasn't found in the password file ) and a naïve programmer blindly calls the normal error reporting routine perror () on every failure, the leftover ENOTTY will result in an utterly inappropriate " Not a typewriter " ( or " Not a teletype ", or " Inappropriate ioctl for device ") being delivered to the user.

In 1966, interactive computing ( via a teletype ) was new.

In a demonstration to the American Mathematical Society conference at Dartmouth College on September 11, 1940, Stibitz was able to send the Complex Number Calculator remote commands over telephone lines by a teletype.

** Schematic diagram of a polarized relay used in a teletype machine.

An alternative to cards was punched paper tape, generated by teletype ( TTY ) machines ; these did need special characters to indicate ends of records.

Teleprinters are now largely obsolete, though they are still widely used in the aviation industry ( AFTN and airline teletype system ), and variations called Telecommunications Devices for the Deaf ( TDDs ) are still used by the hearing impaired for typed communications over ordinary telephone lines.

In 1958, Grissom received an official teletype message instructing him to report to an address in Washington, D. C. wearing civilian clothes.

For a teletype or a typewriter this implies moving of the carriage after typing of a character.

These references served to distinguish formatted final output from normal interactive output from the system, which in many cases in line printer days was also printed on paper ( as by a teletype ) but not by a line printer.

Other systems sold by IMR during the late 1950s included a bill stub reader to the Ohio Bell Telephone Company and a page scanner to the United States Air Force for reading and transmitting by teletype typewritten messages.

Typically, a single 75WPM line supported three or more teletype operators working offline.

Dell purchased his first calculator at age seven and encountered his first teletype machine in junior high, which he programmed after school.

CMS started in the era of teletype-style paper terminals, and the later " glass teletype " dumb terminals.

The power then operated the mechanicals of an electric typewriter to type the encrypted letter, or alternately simply lit a bulb or paper tape punch from a teletype machine.

During this time, the residents ' only contact with the outside world was via the Navy shortwave radio and teletype system, the military MARS radio system, and amateur radio, which allowed residents to talk to anyone by telephone via mainland amateur radio operators ' phone patches.

Bletchley Park is mainly remembered for breaking messages enciphered on the German Enigma cypher machine, but its greatest cryptographic achievement may have been the breaking of the German on-line teleprinter Lorenz cipher ( known at GC & CS as Tunny ).

The teleprinter includes a keyboard, which is the main means of entering text, and a printer or visual display unit ( VDU ).

When a key of the teleprinter keyboard is pressed, a 5-bit character is generated.

When a sequence of start bit, 5 data bits and stop bit arrives at the input of the teleprinter, it is converted to a 5-bit word and passed to the printer or VDU.

The modem is sometimes called the terminal unit and is an electronic device which is connected between the teleprinter and the radio transceiver.

From this analysis, it is clear that the transmission speed is a characteristic of the teleprinter while the shift ( the difference between the tones representing mark and space ) is a characteristic of the modem.

Although its use has decreased in recent years with the demise of Morse code and the obsolescence of the teleprinter, and with the increased availability of native-font software, it is still used for the quick and handy platform-independent recording and transmission of Arabic terms and text.

A teleprinter ( teletypewriter, Teletype or TTY ) is an electromechanical typewriter that can be used to communicate typed messages from point to point and point to multipoint over a variety of communication channels that range from a simple electrical connection, such as a pair of wires, to the use of radio and microwave as the transmission medium.

The native mode of communication for a teleprinter is a simple series DC circuit that is interrupted, much as a rotary dial interrupts a telephone signal.

When the line is broken, the continuous spacing ( open circuit, no current flowing ) causes a receiving teleprinter to cycle continuously, even in the absence of stop bits.

Although printing news, messages, and other text at a distance is still universal, the dedicated teleprinter tied to a pair of leased copper wires was made functionally obsolete by the fax, personal computer, inkjet printer, broadband, and the Internet.

* A teleprinter exchange facility signal that automatically causes a calling station to retry the call-receiver number after a given interval when the call-receiver teleprinter is occupied or the circuits are busy.

A related example is based on a loader for a Nicolet Instrument Corporation minicomputer of the 1970s, using a Teletype Model 33 ASR teleprinter as a paper tape reader.

A telecommunications device for the deaf ( TDD ) is a teleprinter, an electronic device for text communication over a telephone line, that is designed for use by persons with hearing or speech difficulties.

Some have taken Turing's question to have been " Can a computer, communicating over a teleprinter, fool a person into believing it is human?
