DOCUMENT RESUME ED 375 804 IR 016 847 AUTHOR Baker, Christopher; And Others TITLE Telecommunications Handbook: Connecting to NEWTON. Version 1.4. INSTITUTION Argonne National Lab., IL. Div of Educational. Programs. SPONS AGENCY Department of Energy, Washington, D.C. PUB DATE Mar 94 CONTRACT W-31-109-Eng-38 NOTE 26p.; For an earlier version of this handbook, see ED 366 323. PUB TYPE Guides Non-Classroom Use (055) Reports Descriptive (141) EDRS PRICE MF01/PCO2 Plus Postage. DESCRIPTORS Computer Uses in Education; *Electronic Mail; Elementary Secondary Education; Information Dissemination; *Information Networks; *Online Systems; *Science Education; Scientists; Teachers; *Telecommunications IDENTIFIERS *Argonne National Laboratory IL; *Newton Bulletin Board System ABSTRACT This handbook was written for use with the Argonne National Laboratory's electronic bulletin board system (BBS) called NEWTON, which is designed to create an electronic network that will link scientists, teachers, and students with the many diversified resources of the Argonne National Laboratory. The link to Argonne will include such resources as scientists, research programs, and educational programs (workshops, conferences, and instructional materials), and serve as a forum for sharing knowledge, new ideas, and teaching materials. Through the BBS, students will be able to interact with fellow students throughout the nation, and/the BBS will help to build a teacher support group that will work with established teacher-alliance networks and worldwide research networks, including Internet. This manual begins with the mission statement which identifies objectives, primary users, materials, and services of NEWTON. The introduction then examines telecommunications and education and the NEWTON BBS. Additional sections contain information on accessing NEWTON; equipment needed to login to NEWTON; the setup of the equipment; the login procedure; and a list of NEWTON's features including system, personal, and group features. -

Using C-Kermit 2Nd Edition
<< Previous file Chapter 1 Introduction An ever-increasing amount of communication is electronic and digital: computers talking to computers Ð directly, over the telephone system, through networks. When you want two computers to communicate, it is usually for one of two reasons: to interact directly with another computer or to transfer data between the two computers. Kermit software gives you both these capabilities, and a lot more too. C-Kermit is a communications software program written in the C language. It is available for many different kinds of computers and operating systems, including literally hundreds of UNIX varieties (HP-UX, AIX, Solaris, IRIX, SCO, Linux, ...), Digital Equipment Corporation (Open)VMS, Microsoft Windows NT and 95, IBM OS/2, Stratus VOS, Data General AOS/VS, Microware OS-9, the Apple Macintosh, the Commodore Amiga, and the Atari ST. On all these platforms, C-Kermit's services include: • Connection establishment. This means making dialup modem connections or (in most cases) network connections, including TCP/IP Telnet or Rlogin, X.25, LAT, NET- BIOS, or other types of networks. For dialup connections, C-Kermit supports a wide range of modems and an extremely sophisticated yet easy-to-use dialing directory. And C-Kermit accepts incoming connections from other computers too. • Terminal sessions. An interactive terminal connection can be made to another com- puter via modem or network. The Windows 95, Windows NT, and OS/2 versions of C-Kermit also emulate specific types of terminals, such as the Digital Equipment Cor- poration VT320, the Wyse 60, or the ANSI terminal types used for accessing BBSs or PC UNIX consoles, with lots of extras such as scrollback, key mapping, printer con- trol, colors, and mouse shortcuts. -

Modems Matter from 300 Baud to 56K the Modem Is a Gatekeeper, Boundary-Walker, Border-Crosser, Turnstile-Hopper, Time Traveler, and Translator
Modems Matter From 300 Baud to 56K The modem is a gatekeeper, boundary-walker, border-crosser, turnstile-hopper, time traveler, and translator. In the early days of the net, the modem was a technology of distinction. Those who knew the modem's song were identified with it-- they were modemers, inhabitants of a modem world, agents of a modem era. Properly cared for and initialized, the modem's incan- tation revealed a new communicative field enveloping the mundane. Operating at the brittle edge of rationality, the modem was a charged device, transforming data into song using a vibrating crystal to keep time. The term "modem" is a contraction of its two core functions: modulation and demodulation. In practical terms, a modem transmits a stream of digital information (e.g., 1001110100101) over a plain old telephone line by first generating an audible "carrier" signal and then periodically altering, or "modulating," that signal to represent a sequence of 1s and 0s. The receiving modem recovers the 1s and 0s by listening for changes in the carrier signal. The precise pitches and tempo of the modem's song are defined by a "protocol." Communication protocols are produced by committees of engineers aiming to efficiently push the maximum amount of information through a noisy medium. While modems typically include an error correction mechanism, they don't really care about the meaning of the data they transmit. A rogue messenger, the modem is a technology of communication rather than computation. In the late 1970s, dial-up modems brought together the long tradition of amateur telecommu- nications and the emerging technical culture of microcomputing.
