Review on 🔌 Sabrent USB to Serial Adapter Cable with 6ft Cable [FTDI Chipset] - Buy Now by Anthony Bandzz

This adapter solved my problem connecting two old HP graphing calculators to my Windows 7 Pro x64 workstation. I tried using the built in serial port on my Gigabyte EP45-UD3L but it didn't work. The calculators continued to report an invalid command, which meant that the data was not received correctly. I had two choices: use a very old laptop with RS-232, or buy a USB to RS232 adapter. After a quick search I found this adapter had a pretty high rating for a reasonable price (lower than eBay). I got it today and it worked on the first try using the driver that came with the CD and the latest driver installed from windows search from the microsoft driver database. Now I'm happy to be able to use my old calculator again, which I use to do technical calculations at work.
