To null the connection so the cable will activate (fool) any hardware flow control signal that may be required, jumper the follow sets of pins. Connect pins 1,4 and 6 together and connect pins 7 and 9 together. Note that this is unlikely to be required for most modern equipment to operate successfully, especially USB to Serial adaptors.
