IF you connect a PC or Linux system running a terminal emulator, and you can
see the console messages at boot time, then the port is working.
If you can't then either the port isn't working or there is some other problem.
You can send stuff to the serial with echo 'some text' > /dev/ttyAM0.
You can use getty to set the baud rate, as getty does not change the baud rate
back to whatever it was, when it exits.
