problem is my data is flowing in both directions how can i have some sort of handshaking so that no conflict of data occurs.I am using C language both on PC controller .In PC side i am trying to use function bioscom()

You can use RTS and CTS to handshake. RTS (Request To Send) indicate PC has data and will send if uC ready. CTS (Clear To Send) indicate uC ready to receive that data.
