老牌

The xterm program is a terminal emulator for the X Window System. It provides DEC VT102 and Tektronix 4014 

說是最早針對dec t102開發的直接終端機，並沒有視窗考慮 compatible terminals for programs that can't use the window system directly.

This version implements ISO/ANSI colors using the "new" color model (i.e., background color erase). It also implements 

後來他實做了更多，標準色彩模式跟更多相容機種most of the control sequences for VT220, as well as selected features from other DEC terminals such as VT320, VT420 and VT520.

後來x11問世後，他也融入x11世界了，現在應該是每個版本都有了
