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.
ROTE is a simple C library for VT102 terminal emulation. It allows the programmer to set up virtual 'screens' and send them data. The virtual screens will emulate the behavior of a VT102 terminal, interpreting escape sequences, control characters and such. The library supports ncurses as well so that you may render the virtual screen to the real screen when you need to.
JChassis ANSI Terminal Controller is a Java API for controlling ANSI-compliant terminals and terminal emulators such a Linux virtual terminals, xterm, Gnome Terminal, and KDE Konsole. The library can be used to display character styles and colors and graphical characters in those environments. It is a repackaging of various JChassis modules into a standalone library that does not require the JChassis SDK or framework.
JChassis TermUI is an API for simple GUI-like user interfaces on ANSI/VT100-compliant terminals and terminal emulators, such as Linux virtual terminals, GNOME Terminal, and KDE Konsole. The intent is similar to that of the ncurses library, but done in pure Java. Several commonly used widgets are available.
