ATENUC232A USB to Serial Converter USB-A to RS-232 Adapter (35cm) to PDA/Serial (DB9) Port Converter for Laptop PC Modem Printer Network Switch Scanner PLC Controller POS - Windows, Mac, Linux

Works great on Linux, "out of the box". It contains a Prolific PL2303 chip, just like almost all the others. Worked the first time. It's a standard RS-232 serial port, and works at 115200 baud (the maximum standard speed). I did not test any faster speeds.Haven't tested it on Windows or Mac.One caveat is that it requires the correct serial cable: either a "straight through" serial cable, or a "null modem" serial cable, depending on your device. These two wiring standards are incompatible, and it can't switch automatically, so it's up to you, to supply the correct cable! Buy one of each if you are unsure.The adapter is 9-pin male, so your serial cable must be 9-pin female (on at least one of its ends) otherwise you won't be able to plug it in. There's a helpful LED on the adapter that lights up when it's transmitting or receiving data.ATEN is better known as "Iogear" in the USA. Most of Iogear's products are simply relabeled ATEN products. Buy whatever's cheapest at the moment, either ATEN or Iogear, they are the same!Avoid buying a no-name serial converter, though, because there's counterfeit Prolific PL2303 chips out there that are unreliable or just don't work. Even though a USB serial converter is a generic product, stick to a name brand, like ATEN or Iogear, to avoid this.

This worked great, just like a true serial port. Quite satisfied

Genuine ATEN item received in original packaging.This USB to serial adapter is listed to work with NexRemote. Snap to install under WinXP & works like a charm with Celestron NexRemote to control NexStar 8SE scope (Bought 2 / both fine). Included CD has drivers for Win XP, Vista, 7 & 8 as well as Mac, Intel Mac, & Linux. Items received have newer serial # & manual states will work with Win7 & 8, though not tested with either.Item shipped quickly & was well packaged. Although Tekonic is newly launched, since they are a fulfilled by Amazon seller I had little concern.

the product arrived fast in good condition. The software disc with the drivers could be laid out a bit better, but some common sense and you can find the correct driver you need. Installation was quick. I had to reassign the COM port the adapter was setup on, but after that this adapter worked perfectly.I am very please with this purchase.

This is the 4th of the ATEN adapters that I have bought. The others are all still in service and working well. As I have new needs develop for this type of adapter I keep going back to the ATEN product. I have three different laptops that I control my telescope with plus I use one to attach to my weather station, all use the ATEN adapter and I'm very satisfied. I have no hesitation in recommending them to others. Great product.

I have an older serial Ross-Tech VAG-Com cable. With this adapter, I am able to plug my cable into my laptop or tablet and scan my car's OBD2 port. Works every time without any issues. This is the only thing I've used it for, but this alone makes it worth the cost to me.

I have used other brands in the past with install issues or glitches with normal operations, but this adapter worked perfectly no glitches in install or performance.FYI (some of the install folders and files on the install disc are not named exactly as they appear in the manual, but if you know your operating system you should have no problems)

Received product in timely manner. Installed driver on windows 7x64, plugged in adapter and it was found and installed with no problem. hooked up my Snap-On obd2 code reader, it found it and worked flawlessly to transfer info to computer for printing. would highly recommend this to any one needing a serial port adapter.
