Terminal emulation |
|
There are several methods for determining how your keystrokes and screen interact with a public-access site's operating system. Most communications programs offer a choice of "emulations" that let you mimic the keyboard that would normally be attached directly to the host-system computer. In the "old days" of computing, a "terminal" was an input/output device that was a slave of a CPU, such as a terminal for minicomputer or mainframe. Generally, terminals, had no computing power of their own, but simply provided an interface to a remote host computer. "Terminal emulation" refers to a mode (character-based) in which a PC emulates one of these terminals to communicate with a remote host-- typically a BBS computer or a corporate mainframe that only "knows" how to talk to a terminal. |
