rswindell authoredwhen set, force a clear-to-end-of-line sequence to be sent to the remote terminal before sending a carriage-return (CR, '\r') character. This is useful in scenarios where you want to move/home the cursor and *not* clear the screen and then display or execute something that assumes clean lines are being displayed on and thus wouldn'd bother with any clear-to-eol sequences before line-endings. Any scripts that enable this mode should disable it upon exit (e.g. using js.on_exit() to restore the original console status).
