That should take care of it.
As you can see below only user root and group uucp can access the serial ports.
crw-rw---- 1 root uucp 4, 64 Aug 30 2002 /dev/ ttyS0 crw-rw---- 1 root uucp 4, 65 Aug 30 2002 /dev/ttyS1 crw-rw---- 1 root uucp 4, 66 Aug 30 2002 /dev/ttyS2 crw-rw---- 1 root uucp 4, 67 Aug 30 2002 /dev/ttyS3 ...
Do NOT change the permissions or ownership, or you will create security problems.

Hi all folks,
Lucent modem (winmodem) =======================
User can't use modem
As ROOT kppp works without problem. As USER, request for ROOT password will popup, without ROOT password user is not allowed to run Kppp
I made following test
As ROOT # cu -l /dev/modem Connected. AT OK ~[localhost]. Disconnected. #
But it could not work as USER $ cu -l /dev/modem Connected.
It hanged here and I was not allowed to type
A temp file was created /var/lock/LCK...Modem to lock the modem
I have been looking for a solution for sometimes without result? Permission for modem, lock, tty, ttyLT0 (symbolic linked), user group,
and other relevant items, etc. have been checked.
Any advice. Thanks in advance.
