Focusing on how to use a microcomputer as a terminal for searching online databases, this digest addresses the following topics: (1) hardware and software requirements; (2) configuring the software; and (3) basic requirements for specific microcomputers. Special features in communications software which allow microcomputer users to do database searching are described, such as print commands, save commands, access to command mode, format display, default setting, and status indicator. Suggestions for software configuration include telephone numbers for three major database vendors--DIALOG, BRS (Bibliographic Retrieval Services), and SDC (System Development Corporation). Finally, the hardware necessary to use a computer as a terminal is discussed, including interface modules, modems, modular jacks, acoustic couplers, and internal modems. A list of 10 different microcomputers and the hardware and software necessary to use them as terminals completes this digest. (JB)
