Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Hayes command set is a specific command-language originally developed for the Hayes Smartmodem 300 baud modem in 1977. The command set consists of a series of short text strings which combine together to produce complete commands for operations such as dialing, hanging up, and changing the parameters of the connection. Most dialup modems follow the specifications of the Hayes command set. Prior to the introduction of the Bulletin Board System, modems typically operated on direct-dial telephone lines that always began and ended with a single modem at each end. The user would usually dial the phone manually before connecting, or pick it up if it rang. In a few cases the computers themselves had to call a selection of numbers, and for this task they used a separate peripheral device, a "dialer" plugged into a different input/output port on the computer.
