If I install SL4.4 on a laptop and then try to use the /dev/ttyS0 serial port, I find I can't control the ownership and permissions of the port.  It resets from 0660 root uucp to root root and owner rw permissions.  So, I can't add a user to the uucp group to manage usage of the serial port (this works ok on SL5.0.    If I try to just  run everything via sudo, it seems my terminal settings via stty have changed.

I know I'm not using an up-to-date SL release, nevertheless, is this a "known" issue with an obvious work around - so I don't have to reinstall?
