Just as PP suggested, go to LD17 and turn off bug for your tty terminal. Keep in mind, that you should not ignore bug messages, as they could be pointing to a potential issue that needs addressing. Turning off the Bug codes, is like turning your car radio up so you cant hear the clanking in the engine
If possible, find an old PC, and hook up a tty port to it, and use that as your "bug collecting" terminal. Capture everything that goes on in the switch and review it periodically throughout the day.
