Plugged this into my Lenovo Ideapad Flex 5 running Windows 11 and it automatically installed the necessary drivers. I've used it several times for troubleshooting ancient SUN servers and have had no issues whatsoever. It gets bonus points for it being 10' long.

Nice cable. Manufacture sends 25 foot. 10 works fine

I bought this so one PC-based device could control another via serial port (yup, welcome to the 1990's!). It worked for this low-tech application. By my measurement here is the pin wiring. Pins 1, 5, and 9 are wired straight through. Pin 6 is open circuit. Pins 2 and 3 are cross-wired, as are pins 7 and 8.Who knows why the seller description blabs on and on about HDMI and display port. This cable has nothing to do with video!

These work fine for when I need to get into a physical appliance in a data center that has crashed. I plug this in and then launch hyper terminal (you can use the XP version on Windows 7) set the speed/baud rate, etc. and reconfigure if necessary. These appliances just periodically lose their configurations and you have to get a minimal config on them in order to put the backup of the configuration back on them.

I used this in conjunction with Norton Commander for DOS to back up data from a vintage PC that didn't have a working disk drive. It worked great and got me out of a pinch!

If you need to console into a Mikrotik router/switch, this is the cable you need.

Does the job just fine. Decent quality, gave it some abuse and it didn't fall apart or break, so can't complain.

Necesitaba un cable serie (parece mentira que hoy en dia, todavia se necesiten cables de comunicaciones RS232) para la instalación de unos equipos y lo compré esperando que fuera un objeto con una calidad justa pero nada mas de mi opinión inicial.Me encontré un objeto muy bien terminado y de calidad (ya habia probado otros cables de 3metros de longitud y daban problemas a menos velocidad - lo tenia que usar a 115200bps, 8,1,N).Voalvería a comprar otro en caso de ser necesario? Sin duda.

Yamahaのルーター設定のためにクロスケーブルが必要だったので購入。昔はモデムの設定をしたりとRS-232cは必須のケーブルだったのだけど、今はもうパソコン側にもRS-232C端子が付いていないぐらい無くなってしまった。どこかにあったはずなのだがアナログ回線の終了と共に処分してしまったのかもしれない。しかし、現代では注文すれば翌日に到着なので非常に便利。おかげでルーターの設定もできました。

This well made cable has worked perfectly while I have been working with a very old computer and a PC emulating a terminal. During the build, the cable was connected and disconnected numerous times and did not develop any sort of problem.I have used several products from StarTech and have never been disappointed by the design or the quality.
