Change permission problem



Hi all folks,

Permission changed back to its original state after rebooting the PC

Test performed as follows;

$ ls -l /dev/modem 
lrwxrwxrwx    1 root     tty            11 Apr 22 12:24 /dev/modem ->
/dev/ttyLT0 

$ ls -al /dev/ttyLT0
crw-rw-rw-    1 root     uucp      62,  64 May 23 12:18 /dev/ttyLT0


As ROOT
# chmod 777 /dev/ttyLT0)
# ls -l /dev/ttyLT0 
crwxrwxrwx    1 root     uucp      62,  64 May 23 11:38 /dev/ttyLT0 

After rebooting the PC it changed back again
$ ls -al /dev/ttyLT0
crw-rw-rw-    1 root     uucp      62,  64 May 23 12:18 /dev/ttyLT0

Kindly advise how to solve this problem.

Thanks in advance.

B.Regards
Stephen Liu
