This works fine if you are only going to have one person logged in at the console at a time. But it does not help for ssh logins to the box. If you just want to change the permissions for ttyS0, you may want to create a rule for udev after 50-udev.rules that creats a symlink to something like /dev/gmssk and set the permissions. The nice thing about doing it that way is that if you change the port, you just edit the udev rule, and the software still uses the same port. The again, if you want to give access to all the serial ports, you can just add the user(s) you want to have access to the uucp group.
