This makes me wonder about having a new form factor for a serial cable. Something like the RJ11 serial cable Cisco routers use, or maybe using RS232 over USB-C. This way, someone can configure a security sensitive device on a wire or using a cable before it ever sees the network.
What you're talking about is YOST.

The problem with it isn't the signaling at the port, it's getting the serial part to work on the host PC or other device being used. Almost nothing has RS-232 DE-9 port anymore, and even USB-A is becoming less common. Plus the FTDI scandal with cloned chips and nonfunctional drivers is another major problem.
