My old laptop went to the shop for repairs, so I dug out my new one and loaded all the software up and plugged in the Napco provided USB to RS-232 adaptor. It worked with the driver for the USB to serial adaptor I already had loaded for my HAI software. All I had to do was go into the device manager and set the serial port. I don't know if the Napco software will work with higher than the standard ports 1-4 so I just set the adaptor to port one (3&4 were already in use).
Loaded the Napco software, set it for port 1, and plugged into the P9600 I have on my test bench. It worked great and if anything its faster.
Now to go out and use it. Lots of stuff to install and program.
