Keep in mind that the permissions probably won't hold through a reboot
unless you make other arrangements: "adduser www-data dialout" or
similar is "sticky" (if you'll pardon the use of a word that has other
meanings in a Unix context), whereas the ownership of all /dev/ files
is reset by most (?) distributions at reboot so changes you make by
using "chown" or "chmod" are only good temporarily.
