I've used WinISD before and understand it pretty well but I've never designed a box using multiple round ports.

My question is when you enter the number of ports and vent diameter it gives you the port length, when you change the number of ports to 2 the vent length increases and the diameter stays the same.

Is the vent length for both ports or for each port?

With this example is each port 17.52" or is each port 8.76"?

Thanks, but it still doesnt tell me if the port length given is each for do I split it between both?

I'm assuming it's the total port length so I would split it into 2 equal lengths?

Each port.

Greetings SPY, I would highly recommend spending some time reading through this tutorial from JL audio. They give a pretty good technical explanation of mulitiple ports. Here's the link:
