This file was posted on America Online this week. I've found it to be the best source for information about modems, protocols, transfer compression, etc. that I have yet seen. This file is one chapter from a three chapter book entitled "The Joy of Telecomputing" Ordering information is at the end of the file. I hope ya'll find this as informative as I did.

This article is Part One of a three-part report entitled "The Joy of Telecomputing." As a plain ASCII file, it cannot contain any of the illustrations and graphic elements provided in the printed version. For further information about "The Joy of Telecomputing," see Appendix C.
This article should be useful to anyone interested in high-speed modems (or 2400 bps modems with MNP-5 or V.42bis). Most modems mentioned in this article are external units. These modems can be used on any microcomputer system, be it a PC, a Macintosh or an Amiga. Although only certain communication programs are used as examples, the discussions about setting up software apply to packages not covered herein.
It is assumed that the reader knows the basics about going online. For example, we would not discuss how to connect an external modem to your computer, nor would we explain what 8-N-1 means.
This file is in the IBM ASCII format. Each line ends with a linefeed and a carriage return. If you use a Macintosh, open the file with a text editor and get rid of the linefeeds. (I recommend McSink, a shareware text editor widely available. Just launch McSink and open the file, then choose the Convert menu and select Strip Linefeeds.)
To print this document, use a 10-pitch (12 characters per inch) mono-spaced font such as Courier.
Every effort has been made to supply complete and accurate information. However, information contained herein is subject to change without notice and should not be construed as a commitment by the author who assumes no responsibilities for any errors that may appear.
