Such codes are found in com and techniques, the latest being the addition of the ASCII computer code. mon use with computer and line printer devices.

Interchange(ASCII) as well as the older "Baudot" code for RTTY com munications. This paper discusses the differences between the two codes, The Baudot TTY Code provides some definitions for RTTY terms, and examines the various inter facing standards used with ASCII and Baudot terminals. One of the first data codes used with mechanical printing machines uses a total of five data pulses to represent the alphabet, numerals, and symbols.

Teletypewriter Communication Codes
Teletypewriter Communication Codes Gil Smith [email protected] 2001 (Document Notes) Abstract Preliminary -- 5/01 gil smith Corrections or comments to [email protected] This information is pulled from a variety of sources, such as various emails of the greenkeys group. For more discussion of teletypewriter code development, see: http://www.nadcomm.com/fiveunit/fiveunits.htm http://fido.wps.com/texts/codes/index.html http://www.science.uva.nl/faculteit/museum/DWcodes.html FIVE-UNIT CODES: USTTY and ITA2 (aka BAUDOT) There were a few variations in character codes for five-level teletypewriter machines. The two most-common character codes were ITA2 and USTTY (a variation of ITA2). The USTTY and ITA2 5-level teletypewriter codes are commonly referred to as "Baudot" codes. While this is technically incorrect, these popular 5-level codes evolved from the work of Jean Maurice Emile Baudot of France - - it seems fitting to accept the defacto reference to "Baudot" as implying USTTY or ITA2 codes, since they were the 5-level codes that saw practical use in teletypewriter systems. However, the true Baudot code dates to around 1874, when Baudot designed the "Baudot Multiplex System," a printing telegraph. The system used a 5-level code generated by a device with five keys, operated with two left-hand fingers, and three right-hand fingers -- this required great skill on the part of the operator who entered the code directly. However, it was still a major improvement in communications -- prior to Baudot's design, communication was carried out using Morse code with a telegraph key. The 5-level "Baudot" code was actually designed by Johann Gauss and Wilhelm Weber. -

OS 360; PI. I; Teletype ABSTRACT The design and operation of a time-sharing monitor are described. It runs under OS/360 MVT that supports multiple application program interaction with operators of CRT (cathode ray tube) display stations and of .a teletype. Key. design features discussed include:1) an interface. allowing application programs to be coded in either PL/I or assembler language; 2) use of the teletype for:subsystem control and diagnostic purposes; and 3)a novel interregional conduit allowing an application program running under the Chapel Hill Alphanumeric Terminal (CHAT)_: monitor to interact--like a terminal operator--with a conversational language processor in another region of the OS/360 installation.

Published in: Encyclopedia of Library and Information Science, vol. 49 (New York: Dekker, 1992), pp. 268-78 Author’s address: [email protected] WORD PROCESSING (HISTORY OF). Definition. The term and concept of “word processing” are by now so widely used that most readers will be already familiar with them. The term, created on the model of “data processing,” is more vague than commonly believed. A human editor, for example, obviously pro- cesses words, but is not what is meant by a “word proces- sor.” A number of software programs process words in one way or another--a concordance or indexing program, for example--but are not understood to be word processing programs.’ The term “word processor” means a facility that records keystrokes from a typewriter-like keyboard, and prints the output onto paper in a separate operation. In the meantime the data is stored, usually in memory or mag- netic media. A word processor also can make improve- ments in the stream of words before they are printed. At their most basic these include the ability to arrange words into lines. An “editor,” such as the infamous EDLINE distributed with the Microsoft Disk Operating System (MS-DOS), lacks the ability to structure lines. Commonly a word processor is understood to be a software program, and in the 1980s and 1990s it usually meant a program written for a microcomputer. However, preceding this period and continuing through it there have been hardware word processors. These are pieces of equip- ment sold for the sole purpose of word processing, con- taining in one package a keyboard, printer, recording and playback device, and in all recent examples a video or liquid crystal display screen. -

During recent years, however, their use has been extended beyond this tradi- tional field to a rapidly growing number of non-telegraphic applications such as the provision of input and output facilities for digital computers and the increased automatisation of existing systems such as punched card accounting and mechanised addressing. As a result of this sudden increase in the number of applications that are being found for Teleprinters and Punched Tape, considerable interest is being shown in this equipment by engineers and others who wish to discover whether it can be applied to their own special problems but who lack sufficient knowledge of the basic principles involved to permit them to do this. -

COMPUTER TIME-SHARING (T-S) "AN ENGINEERING TOOL" FOR THE ENGINEERING APPLICATIONS OF THE SMALL COMPANY BY JAMES BINFORD SUMMERS, 1938- A THESIS submitted to the faculty of the UNIVERSITY OF MISSOURI - ROLLA in partial fulfillment of the requirements for the Degree of MASTER OF SCIENCE IN CIVIL ENGINEERING Rolla., Missouri 1970 T2478 c.l 62 pages Approved by ~Jt£.~ ~.(advisor)~~ 187982 ~tiM/ ii ABSTRACT The objectives of this investigation were to illustrate the capabilities of the time-sharing (T-S) industry, identify the means by which the small sized company, with a need to solve engineering problems, can best be served through T-S, and to present T-S to these potential users. Investigation was made of distinctive T-S services to formulate a com posite of the T-S industry. Examples of three distinctive T-S services were used within this composite to exemplify the variations of services within the industry.
