IMO the right way to do this is to add the user to the group which is
allowed access to the device... for example

on my system, /dev/ttyS0 points to /dev/tts/0

an ls -l /dev/tts/0 gives

crw-rw----    1 root     dialout    4,  64 Dec 31  1969 /dev/tts/0

Which means that the user root has rw access and the group dialout has
rw access as well. So to give a user rw access, you can simply run (as

adduser <username> dialout

then log out and back in and you should be all set.

This is how things should work for all devices

Hope that helps
