Review: Works perfect on Windows 10 64 bit-Plug and Play - I liked that Windows 10 recognized it instantly and loaded drivers for it, the disc was not necessary. This adapter is mechanically exactly the same as the COM connector that is found on the XP and older computers. I plugged my radio programming cable into it and the computer found it in 2 seconds. Communication to and from the radio was faultless. I don't know why other reviewers are complaining about the female threaded studs, perhaps they don't know what a proper COM jack is supposed to look like? I did notice some other devices similar to this one that have the correct male pins but have the hold down bolts of a female plug instead of the nuts found on a jack, but those by definition are not standard COM jacks, but are instead a mechanical corruption of the original concept. I find nothing to dislike with this device other than perhaps it could use a bit longer wire.
Review: If you need to add RS-232 - I have two of these. I plug them in and they just work. I have a computer hooked up to my firewall's console port just in case I need to communicate with it in that manner. The other one I keep in my tool bag in case there is other network equipment I need to hook up to. Preliminary build of some networking equipment this would be invaluable for. There are still times you need a COM port. It's nice to be able to simply add it to a more modern computer. it has onboard lights so you can see activity. Really a nice device and never had problems with it.

### ⭐⭐⭐⭐⭐ Works with Windows 11
*by K***H on September 26, 2022*

Finally found an adapter that works with Windows 11! Note, it is a bit tricky to get the driver working. The website is not much helpful, but I managed to get it working after several attempts.
