Is there a USB alternative to NI PXI-8331 9-pin COM port

[pwalake]

I am using NI PXI-8331 which communicates through 9 pin COM port . I need to know if there is USB alternative to this COM port which i could directly connect to my laptop (Win 7) which makes my work easier. If there is, then how and where can I get it?

It's not a com port!

There's this for laptops -https://www.ni.com/en-us/shop/category/pxi-controllers.html?productId=118776
