Newline

  When DECterm receives a line feed (LF), form feed (FF),
  or vertical tab (VT) character, the cursor moves to the first
  column of the next line.  When you press Return, both a
  carriage return (CR) and line feed are received.

  If you click on the Newline option and DECterm receives an
  LF, FF, or VT character, the cursor movers to the current
  column of the next line.  When you press Return, DECterm
  only sends a CR.
