I had thought this adaptrer was correct...http://www.ebay.com/itm/USB-to-RS-232-RS232-Serial-9-Pin-DB9-Adapter-PC-PDA-/180681118105?pt=US_Parallel_Serial_PS_2_Cables_Adapters&hash=item2a116f1199

but i guess it may not be.
(UPDATE) I HAD ONE PIN SOLDERED ON THE DB9 IN THE WRONG PLACE. THANKS FOR YOUR HELP THOUGH.
