    StarTech ICUSB232DB25 reviews

    USB to RS232 DB9/DB25 Male to Male Serial Adapter Cable (Gray) is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from A life saver! For those few times left you need a serial cable, and you don't have a computer built after 1995 (well, an old one, anyway), there's this guy/gal/cable. It works, the drivers installed flawlessly, the cable did its job, and I was able to lie to terminal software and tell it that a USB port was a serial port. YAY!
    Date published: 2016-06-29
    Rated 5 out of 5 by from Excellent technical support Easy to install and technical support was quick and available when issues came up where USB cable was not identified by the computer. Works great now!
