The MARK output comes from the syslog deamon, it just tells you that it's alive every now and then.

If you don't want any log output to /dev/ttyS2 you should change the /dev/console link and make it go somewhere else, /dev/ttyS0 (COM1) maybe? If you don't want any log output to any serial port at all you can replace the /dev/console line in /etc/syslog.conf. I don't think there are any other applications that use /dev/console, but to be sure you should change it to another port or remove it. A lot of applications writes to the syslog via the deamon when something bad happens so I think you want to store the log somewhere (e.g in a file in /tmp, which is the mount point of the RAM-disk, instead of /dev/console). You can limit the size of the log using "-o <max size>" (see /etc/inittab) so that it doesn't eat up all your RAM.
