I N T R O D U C T I O N These days, there is a great deal of talk about the Information Superhighway. The world of telecommunications is experiencing astonishing growth. BBSs (Bulletin Board Systems) got their start in January 1978. That was when Ward Christensen and Randy Suess produced the first BBS software. They called their BBS software CBBS for Computer Bulletin Board System. They wanted to electronically emulate the cork bulletin boards found in public areas such as meeting halls or laundromats. Here, people could post messages on all kinds of subjects. All you needed was a computer, a modem, modem software, and a phone line. In the early days, most people who used BBSs were experts in computers. This is not true today for a number of reasons. Modern communications software is much easier to use. The BBS software is dramatically improved. Modems are much faster and better. Today, there are at least 55,000 BBSs in the United States alone. It is estimated that by the year 2000 there will be around 20 million BBS users in this country. BBSs offer message systems, private e-mail, and usually a huge library of files. Most BBSs can be accessed by almost any modem software program. However, some commercial online services (for example, America Online and Prodigy) require special software to obtain access. Incidently, "modem software" is another name for "terminal program," which is another name for "telecommunications program," which is another name for "communications program." All these terms mean the same thing, and this brings us to the most perplexing problem of modems. The most daunting aspect of telecommunications is the unique terminology. If you are dumfounded by terms such as stop bits, parity, FOSSIL driver, and UART, you are not alone. It behooves the gentle reader to first check out the section on Telecommunications Terms to get a handle on this peculiar jargon. =========================================================
