Emulation

The emulation supported by GNOME terminal is the same as the xterm program as provided by the X consortiums xterm program (which is in turn an almost complete emulation of the DEC VT102 terminal).

The GNOME terminal supports the same extensions to the VT102 that the xterms provide (trough special escape sequences. More recent changes to xterm have also been incorporated into gnome-terminal as they have been discovered. This includes emulation of the newer DEC VT220 escape sequences.
