working on power line communication

"As i am new to 'C' I am not getin how to start with the serial communication implementation."

So, are you clear on how to do the "serial communication implementation" itself - aside from implementing that in 'C'?

The actual interface will be totally unaware of what programming language you use - it just works as described in its datasheet - so you need to understand how the underlying platform works before you can think about implementing that in any programming language!

As Per says, have you decided which particular serial interface you are going to use?

Have you checked for application notes, examples, reference designs, etc on the NXP site, or your distributors site, or elsewhere on the internet?

yes i have gone through the perticular datasheet.It has been given that,the perticular pin should be low to transmit orto receive.In this manner i have understood the theory of protocol implementation.
I am using RS232 interface with c51
