You should read: /usr/share/doc/base-passwd/users-and-groups.html

dialout

    Full and direct access to serial ports. Members of this group can
    reconfigure the modem, dial anywhere, etc.

 $ ls -l /dev/ttyS*
crw-rw---- 1 root dialout 4, 64 Jul 17 09:09 /dev/ttyS0
crw-rw---- 1 root dialout 4, 65 Jul 17 09:09 /dev/ttyS1
crw-rw---- 1 root dialout 4, 66 Jul 17 09:09 /dev/ttyS2
crw-rw---- 1 root dialout 4, 67 Jul 17 09:09 /dev/ttyS3

That is what it means.
