To have something send to your PC you need a PRINT statement
PRINT "This is a test" will go to the serial port of your microcontroller, through the MAX232, through the cable to your PC with hyperterminal
Why not start with a small program just to test serial.
$regfile = "89s8252.dat"
$crystal = 6000000
$baud = 9600
Do
print "This is a test"
Wait 1
Loop
End
This will send every second the line This is a test to your serial at 9600 baud. You should receive it on your hyperterminal screen.
Could you give it a go?

thanks its working . but i need a code for send all dtmf code to pc through rs232 of 89s52 controller.
i dont know how to write a code to send all dtmf code to pc as digital
send me the code pls

I am an electronic hobbiest and want to develop some automation projects using the DTMF.
Can you please tell me to understand the circuit making using the DTMF?
What IC is needed for it and how it encodes and decodes the commands?
Also what interface it use with the 8051? _________________ printed circuit board manufacturing

sultanm9000:
The schematic you have added is for an atmega8, so perhaps your question should be asked in the Bascom-AVR part of this forum.
Is it possible to show us what you already have written in Bascom-AVR so far?
The remarks in the drawings are German. This is a schematic of a DTMF signal generator. It should be connected to a phone hearing part. 600 ohm.
BTW, I found the schematics with a lot of extra information on this site
http://www.mikrocontroller.net/topic/40678
You could at least put a link to this site in your question....

HuntAvila:
I did a search in this forum on DTMF and got a list of examples and chips to use

Have fun
