1 The xterm program is the standard terminal emulator for the X 2 Window System. It provides DEC VT102/VT220 and Tektronix 4014 3 compatible terminals for programs that can't use the window 4 system directly. If the underlying operating system supports 5 terminal resizing capabilities (for example, the SIGWINCH 6 signal in systems derived from 4.3bsd), xterm will use the 7 facilities to notify programs running in the window whenever it 8 is resized. 9 10 WWW: https://invisible-island.net/xterm/
