10bd37d32SmrgThe xterm program is the standard terminal emulator for the X 20bd37d32SmrgWindow System. It provides DEC VT102/VT220 and Tektronix 4014 30bd37d32Smrgcompatible terminals for programs that can't use the window 40bd37d32Smrgsystem directly. If the underlying operating system supports 50bd37d32Smrgterminal resizing capabilities (for example, the SIGWINCH 60bd37d32Smrgsignal in systems derived from 4.3bsd), xterm will use the 70bd37d32Smrgfacilities to notify programs running in the window whenever it 80bd37d32Smrgis resized. 9
