Viewing SPI i/o data


I am attempting to interface my BL2600 with an AD9858 DDS evaluation board. The DDS board has a parallel SPI interface (though the chip itself also works with 2 and 3 wire SPI). I am at the point where I am sending messages to the DDS board, but cannot view any useful data coming back form the DDS, nor is the DDS doing the operations I am requesting. Any tips on how I can view (maybe in hyperterminal) exactly what is sent via SPI and what is received?
