Gerry, I own and use a Keyspan USA-19HS (now Triplite) and it indeed is a great product, but it only has 9 pins whereas the original spec is a 15 pin connector (DB style). Without changing the model number, the parts inside the USA-19HS have changed a few times. They have great support for all common operating systems and update drivers as needed to cover Microsoft's flavor of the day.
http://www.lammertbies.nl/comm/cable/RS-232.html#pins has a good description of the protocol. Having said that, most stuff today can be configured for Xon Xoff and work with only 3 wires (Tx, Rx and ground). That's true for CAT control on our K3's and most modern radios. In fact Elecraft uses the other pins for non-RS-232 purposes. We need more info on the gizmo!
