I have a serial port
/dev/ttyS2 that is connected to a supervisor. Normally, I use this line to send commands back and forth between CPU and supervisor.
However, under some settings, I want to just redirect the entire console to this port.
I can achieve this via a reboot and updating the uBoot kernel variable to direct
console=ttyS2,115200. But is there a way to achieve this without a reboot?
