my project is interfacing 8 sensor to 8 input of 89c51, when ever a sensor triggers a character should send to pc
my problem is whenever a sensor triggers many character are sent to pc (similar character example "AAAAAAAA")
I used timer circuit for +ve edge using NOT GATE and AND GATE but still 3 or 4 character are sent to pc

*)Is it possible to programmatically clear 89c51 pin once it is declared as input pin ?
*)Is read and write operation using RX and TX pin simultaneously possible?(multi processing is there in 89c51)
*)which microcontroller IC is it possible to learn if 89c51 assembly language is known (85%)

please answer urgently
