hello everyone

right now i'm in the middle of finishing my thesis which is about speech recognition.i'm using 8052 to sampling my sound and send the data to my pc through serial comunication.i'm using 8052's timer 2 because i need to sample my sound every 125 micro seconds.

but the problem is,i can't use serial interupt along with timer 2.i don't know what's the problem.after that,i try to disable the serial interupt and finally i can send my data to my pc.but there's another problem.now my 8052 can't receive the data my pc trying to send because i dissable the serial interupt.from what i know,if i activate the serial interupt,i can receive data from my pc automatically.

what i want to know is:
1. is my method of deactivate the serial interupt correct?
2. if it is,can you teach me how to receive data from pc without activating the serial interupt?

thx a lot!
