hi to all...
actually i checked the communication is taking place via the rs232 cable. For that i installed the vcp driver and tried to communicate using the hyper terminal . badly , it wasn't communicating. i gave the 16(trans) and 17(rec) pins to the rs232 cable's corresponding rec and trans pins... and ground to 5th pin. why it is not communicating ?
pls help
You can not connect the TX/RX pins of the FTDI chip directly to a RS-232 cable connected to a PC's RS-232 Port. You would need a MAXIM RS-232 transceiver device or equivalent, otherwise the FTDI chip could be easily damaged.

RS-232 voltages levels can be in the +/- 15V range, which greatly exceeds your FT2232H devices +5v I/O pin tolerant rating.
