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: Great little tool - A very useful device. Incredibly tolerant of everything I have subjected it to. Worked flawlessly with the drivers included (on a 7cm CDROM) on Windows XP and XP Pro. Ubuntu recognized it with native drivers. Works with arbitrary baud rates correctly under Windows but Linux takes a bit more work. On Ubuntu it does work correctly with standard 16550 UART speeds right out of the box. Neatly assembled and sturdy for its size. Good quality receptacles on both ends (USB and DB9). Recommended for the price. ## Features - WHATS INCLUDED - 12 Inch USB to RS-232 Serial Adapter, User Guide/Instruction Manual, and Driver Disc - FEATURES - High speed serial port with the baud rate up to 921.6K bps.

The website is not much helpful, but I managed to get it working after several attempts. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/2515707-usbgear-12-inch-usb-to-serial-rs-232-db-9](https://www.desertcart.it/products/2515707-usbgear-12-inch-usb-to-serial-rs-232-db-9) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-14*
