    Hi
    I’m using rs232 to communicate between a pc and an avr atmega8 micro controller. I tried to simulate the circuit using isis proteus with com0com virtual COM driver. when I simulate the circuit it gives me “logic contention detected”. I assume that something wrong with my circuit design but I can’t understand the meaning of that “logic contention detected” maybe because both are same directions but when Iook around in the net i find that they use the same wiring desing like I did?
    thank you
