Typically, ttyS0 has GID uucp:
rob@rob:~ > ls -l /dev/ttyS0
crw-rw---- 1 root uucp 4, 64 Apr 26 13:55 /dev/ttyS0
In order to get access to ttyS0, make sure the user account you are
using is a member of group uucp, e.g. in /etc/group, locate the line
for uuco and append your login name to the list of users.
Cheers
