Review: Works with my Agilent/HP equipment! - I bought one of these cables a couple years ago to talk to my Agilent 34401A precision meter and have been happily using it since. Recently I tried buying a less expensive one from another vendor and was sadly disappointed that while the cable was recognized by my computer, it failed to communicate with my meter. So, I just bought a second one of these, and it simply works. It's so lovely to have a thing just work... and this cable works.
Review: Good reliable UBS to null modem cable - One of the nicest null modem cables I've used. Works flawlessly in Windows 10 off a USB 3 port. I love how it has lights on it so I can confirm rcx and trx signals. I've used this successful to log into a number of network appliance consoles. No drivers were needed in Windows 10, it was plug and play. It does come with a driver disk if you need it for older OSes. Due not that the DB9 side stick out a little bit further than normal because it has the electronics in it for the USB to Serial conversion, keep that in mind if you have to work in a tight space.

### ⭐⭐⭐⭐⭐ works great
*by R***J on August 1, 2013*

I really needed a straight through cable, but all the ones I had tried were incompatible with my application, even others that claimed they had the FTDI chipset I required. I lucked out because it was actually an accident (didn't notice the Null Modem part) that I bought this cable. My device recognized the cable right away (which was further than I had gotten with any of the others), but would still not work. After some troubleshooting, I realized this was a null modem cable instead of straight through. No sweat; I ordered one of these bad boys ( DB9 Male / DB9 Female Null Modem Mini Adapter ) to cancel out the null modem & flop it back to straight through and BAM! It worked! Good quality cable and I would recommend it to anyone who needs this type of cable.
