This cable worked exactly as I needed it to. I bought an 8 port Cisco 3560 switch to play around with, but I didn't have a system with a serial port. I found this cable and it works exactly as I expected. I had to download the FTDI drivers because Windows 10 Pro didn't install them automatically. After installing the drivers, I found the COM port mapping in Device Manager and used putty to connect through the Cisco console port. I was able to set up the switch with no problems.
