#100651 - ah my eyes!
Responding to: ???'s previous message
Forget including a CLR P2.0 to "fix" the fundamental flaw!
In view of your intention to connect eye piercing lasers and in view of the fact that your average 8052 will have all port pins HIGH after reset, using HIGH as the level to switch stuff ON doesn't seem like the best idea in the world, eh?
Sounds more like an insight you need to correct before it turns into a bad habit. One of the ways to get rid of the brick walls the first of which you have just experienced, is to clear up old and prevent developing new bad habits.
