I have to ask, The RX signal is the one [from the Receiver Without your comparator connected too and a Pull-up on Vcc] or at the output of your LM741.. which will never work as is (forget pin 5 and 1, and connect pin 3 directly to RX pin).

Maybe the following link will help you a little bit

It' s not the output from my LM741. At the moment my Rx data pin connected directly to port A.0. also not using pull up on vcc at that time. In your opinion., should I use filter??
