mov p2,a
cpl p3.7
jmp start;
 
OK...you'll need a bit more code than that to make this thing work. However, I need a bit more information as to what your project is supposed to do when all is said and done. Can you give me a description of what you are trying to make this circuit do?
 
i simply wants to switch on the relay connected on p2 ON & OFF by pressing 1 & 2 from mobile

data is changing on o/p of dtmf but P89v51rd2 is not reading it and not giving o/p on p2
