Overview
xterm is a terminal emulator for the X Window System, designed to provide compatibility with DEC VT102 and Tektronix 4014 terminals for applications unable to directly utilize the window system. Operating as a separate process for each window, xterm allows execution on both local and remote machines via the X protocol. It supports ISO/ANSI colors using the modern color model and implements a significant portion of the control sequences for VT220 terminals, along with selected features from VT320, VT420, and VT520 terminals. The tool facilitates interaction with programs through terminal descriptions, adapting over time to support advanced features, evolving from VT102-based descriptions to VT420-based descriptions. xterm is primarily utilized by developers and system administrators needing a reliable terminal environment within the X Window System, offering a versatile and customizable interface for command-line interaction and application execution.
