I would have loved to have seen that ono pop up on the scrren.
Back in 1994, Boeing considered equipping each seat with a serial modem.
Laptop users could hook up to the modem and dial out. (Dial-up was the primary means of connecting to the Internet back in those days.)
We chuckled at the though of attaching the serial cable and getting a Plug-and-Play pop-up message:
New device detected: Boeing 747
