A lot of times you can make RS 232 work even without the handshake lines like CTS, DTR, RTS.
You loop back pin 4 to 5 of the 25 pin D connector, and you hook 6, 8, and 20 together. 2, and 3 are your transmit and receive, and pin 7 is the common. Pin 1 is chassis ground, but do not share it with 7. For 9 pin RS 232, Google "RS 232 hook up" and you should get diagrams of connectors commonly used.
