A serial port "looks" like a file to Python or any other program.
If you can print to the console you can write to a serial port.
I assume you are running on some UNIX-like OS. Open /dev/ttyS0 and
write bytes to it. You need to set permissions so the open will work
Echo "Hello World" > /dev/ttyS0
should send a byte stream out to the first serial port on the machine.
You can use "stty" to set the port speed and other parameters. Se "man
stty" or just "stty --help"
