SONAL

I want to control my monitor features using DDC2BI
protocol which is also known as access.bus protocol
defined by VESA
standandard, whcih has some predefined functions such as
getsda(),setSDA,getSCL(),SetSCL(). These functions allow
thedata to be passed on to the VGA
port's pin 12 and 15, SDA and SCL respectivelly.
Does this functionality is given in the graphic driver and
can i
access this functionality through my application or by
writting some
driver?
If so please let me know to access this functionality

Finally I want to send predefined data to monitor and want
to receive the data from monitor.
Please let me know how can I do that, may be through
driver or application or. ????????

Yes, I believe the chipset & driver do support this capability. The Chipset
Datasheet available from the Intel website might help you:

...in particular, pages 11 & 135.

Hope this helps..
