USB Serial Adapter - Ultimate
[XS880]

Excellent product right out of the box. While waiting for my order to arrive, I downloaded the drivers and installed them. When the cable came in, Windows completed the installation and assigned me a COM port.

I'm using this product to connect my Windows 7 Laptop to my TRS-80 Pocket Computer 2's RS-232C Interface, which is attached to my Pocket Computer. I have terminal connectivity as well as the ability to load and save software between my Laptop and the PC-2.
