Start uxterm center of screen3/20/2023 ![]() This option indicates that auto-wraparound should be allowed. This is equivalent to setting the vt100 resource activeIcon to " true". This option enables active icon support if that feature was compiled into xterm. This is equivalent to setting the vt100 resource activeIcon to " false". ![]() ![]() This option disables active icon support if that feature was compiled into xterm. ![]() This option indicates that xterm should do text cursor highlighting based on focus. By default, xterm displays a hollow text cursor whenever the focus is lost or the pointer leaves the window. This option indicates that xterm should always highlight the text cursor. This option causes the DECCOLM escape sequence to be recognized, and the xterm window will resize appropriately. Normally, the VT102 DECCOLM escape sequence that switches between 80 and 132 column mode is ignored. Print the version information for xterm, and exit. If no shell is specified, and the SHELL environment variable is undefined, xterm uses the Bourne Shell, /bin/sh. This pathname can be an absolute path or a relative path, and xterm will search the user's PATH environment variable for the specified shell if it cannot find it. This shell can be changed, however, by providing a parameter to xterm, after all other options, which specifies the pathname of a shell to run. When xterm runs, it normally checks the SHELL environment variable for which shell to run. The -version and -help options are interpreted even if xterm cannot open a display, and along with the -class option, are checked before all other options. If an option begins with a " +" instead of a " -", the option is restored to its default value. Originally written in 1984 for the DEC VAXStation as a stand-alone program, xterm was quickly integrated into X, and today most X terminal emulators are variations of the original xterm code. Several instances of xterm can run at the same time within the same display, each one providing input and output for a shell or another process. See Window Size Sync Script for more.Xterm is the standard terminal emulator of the X Window System, providing a command-line interface within a window. We've also put together a script that can be run on some types of target device that will automatically query the terminal for the current window size and set it accordingly. Serial 1.1.7 and later provide a "Send Window Size" ⌘ + y shortcut that automatically sends the appropriate command to adjust the window size to the remote device. If the current window size is 132x48, for example, you would type: stty cols 132 rows 48Īfter doing this, screen-based programs such as vi and emacs will now fill the screen. Most Unix machines support the "stty" command to set the current screen size used for formatting output from programs. In bash, you would type the following: export TERM=xterm-256color Window Size We recommend setting TERM to "xterm-256color" if this is supported by your device. To set the terminal type, you will need to set the "TERM" environment variable. Many devices assume 80x24 and a terminal type of VT100, but if you're connected to a Linux (or other Unix) based machine, you can make use of larger window sizes and use more advanced terminal features. If the current size of the terminal window gets out of sync with the remote device you may experience visual artifacts and the scroll back buffer may not work correctly. As a result, you will need to configure these manually on the remote machine for the screen to display correctly. This channel does not exist when using a serial port, however. When connected to another machine via SSH or Telnet, the current screen size, terminal type, and other environment variables are automatically transmitted to the remote device using an out-of-band communications channel.
