Interfacing (DSI, CSI, I2C, etc.) • Re: console=serial0 alias changes on newer bootrom version.

if no serial cable is detected on the dedicated UART header (J6).

How does it detect a serial cable is connected ?

Figuring out if something, anything, is connected to a UART port is usually difficult to impossible so I am intrigued.
