Almost certainly the chmod commands did work. But almost certainly
with serial port devices the processes that come by later to open them
will change them to something else.
Please try this:
/bin/chown uucp:uucp /dev/ttyS2
/bin/chmod 660 /dev/ttyS2
ls -l /dev/ttyS2
Or possibly the following in case the output is lost to the screen.
/bin/chown uucp:uucp /dev/ttyS2
/bin/chmod 660 /dev/ttyS2
ls -l /dev/ttyS2 > /tmp/ls-l.ttyS2.out # Save output in file.
I find it likely that the you will find that those commands worked and
it was only later when the files were changed again.
