Eterm is a vt102 terminal emulator intended as a replacement for xterm. It is designed with a Freedom of Choice philosophy, leaving as much power, flexibility, and freedom as possible in the hands of the user. It is designed to look good and work well, but takes a feature-rich approach rather than one of minimalism. Current features include color support, background images (all Imlib-supported formats), theme support, and pseudo-transparency.
Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets).
Twin is a text-mode window environment. It turns a text terminal into a X11-style display with window manager, terminal windows, and can also serve as display for remote applications. Each terminal window provides the functions of a text-mode Linux console. Twin runs on X11, libggi, itself, the Linux console, and any termcap/ncurses-compatible tty. It supports multiple simultaneous displays, and can attach/detach each display on the fly.
Wterm is a color VT102 terminal emulator for the X Window System. While lightweight, it provides an elegant interface, including NeXTSTEP style scroll bars and an application menu that integrates well with the Window Maker window manager and GNUstep based applications. Wterm works well with any window manager or desktop environment. Other features include background images, transparency, and reverse transparency. Support is included for the Latin, Chinese, Greek, and Kanji character sets. An extensive set of runtime options is available.
xremote is a simple tool that lets you grab the mouse and keyboard of another machine and control them with your local mouse and keyboard. It creates a form of remote control of other machines. All mouse- and keyboard-actions on the local machine are forwarded to the remote display.
The xterm program is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.
