Dear Sir,
Thank u for the interest u had showered upon to my request.I feel real sorry ,as i didn't know that i would be charged for the enquiries in this website.
Without knowing that i had troubled u.
i was fetched here with less bucks.
Right now i cant give anything other than thanking u for ur deeds.
Mr.Michael Karas Sir,had given a source code for duplex UART for simultaneous tx and rx using 8x751/752 controllers, i m using 8052,but the source code holds good for my prob.
Once again thanks every1 for ur fast reply.
