What xterm is

xterm is a terminal emulator for the X Window System, available for Linux, macOS, and Windows. It emulates DEC VT102 and VT220 terminals, selected features from VT320, VT420, and VT520, and Tektronix 4014. Separate xterm windows can run on remote machines and display locally over the X protocol; SSH support is also listed. The current version implements ISO/ANSI colors using background color erase. Where the operating system supports terminal resizing, xterm can notify programs in its window when the size changes. It works with different flavors of the Athena widgets and supports scripting. The official site links to source and archive downloads, and the FAQ points to a manual page for command-line options, X resources, and other configurable settings. Related components add support for encodings beyond ISO-8859-1 and UTF-8, X resource support, and TrueType fonts. The FAQ documents known limitations, including color behavior that may fall back to monochrome. xterm is free, with no paid plans or usage limits stated.
