Today, It started working mysteriously. I'm sending 65 ("A") and PIC adds +1 and writes back 66 ("B"), so expected result is printing "B" every second.
I think it was not working because of some noise.
You can see this video to understand why I am suspecting about noise :

As you can see this noise occurs at the half of the cable when I get closer my finger. I can touch the other half of cable.
Isn't this interesting.
