IBM systems typically communicated over a Bus and Tag channel, a coaxial cable using a proprietary protocol, a communications link using Binary Synchronous Communications or IBM's SNA protocol, but for many DEC, Data General and NCR (and so on) computers there were many visual display suppliers competing against the computer manufacturer for terminals to expand the systems. Typically terminals communicate with the computer via a serial port via a null modem cable, often using an EIA RS-232 or RS-422 or RS-423 or a current loop serial interface. IBM 2250 Model 4, including light pen and programmed function keyboardMost terminals were connected to minicomputers or mainframe computers and often had a green or amber screen. Examples include the family of terminal control sequence standards known as ECMA-48, ANSI X3.64 or ISO/IEC 6429. Terminals usually support a set of escape sequences for controlling color, cursor position, etc. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine.

These may be running either on the same machine or on a different one via telnet, ssh, or dial-up. A terminal emulator inside a graphical user interface is often called a terminal window.Ī terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications.

Though typically synonymous with a shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces. Windows Terminal, an open-source terminal emulator for Windows 10Ī terminal emulator, terminal application, or term, is a computer program that emulates a video terminal within some other display architecture.
