There are two commands you should become familiar with chown (to change ownership of a file or directory) and chmod (to change permissions for the owner, group, and world of a file or directory). Also, learn chgrp.
Issue the commands:
to read the manual pages for each command.
chown root:dialout /dev/ttyS0
chmod 660 /dev/ttyS0
After doing so, do the ls -l /dev/tty[AS]* to see the new ownership and permissions of both AMA0 and S0.
I advise getting some system administration knowledge, you can start with articles like https://opensource.com/article/17/7/20-sysadmin-commands
