22 Apr 2008 4:12 problem in interfacing 89c2051?

Hi friends,
I am doing project named Auto Measurement of Current from power supply for one of my application.
I am amplifying the analog output using an OP-Amp OP07,the amplified output is given to ADC,there i am converting to digital,this digital value i am taking at one of the Port of microcontroller(89c2051).I want to get this value using serial communication.for that i have connected the microcontroller to max233.

my problem is no value is displayed in the hyperterminal.
can any body tell me what problem do i have?
The code i have used is attached as text file...

thanks in advance.[/tex][/code]
