In her book, former ABC news person Lynn Sherr writes about how, for one election, she was giving exit poll results. The graphics people had rigged up a graphic that would spring up at the end of her desk, and told her to point at a spot on her desk when the graphics were supposed to pop up. She had trouble getting that down, so they took some bottle caps and glued them to the desk as "buttons" that she would "push" to bring up the screens. Peter Jennings got such a kick out of the display that during a slow period of returns, he insisted on going over and pushing one of the buttons.
So I would be 99 44/100 percent sure nothing was connected to anything at the Lingo desk.
