does what it is supposed to fo 6/10/2016 12:16:36 PM

Pros: Plug & Play with Win 7 Pro x64

Cons: Wish the cable was a little longer.

Overall Review: I had one from E&*@ which must have been one of the notorious China knockoffs and Windows wouldn't recognize it. This one worked perfectly.

Awesome Product, Works Great with Mac Air 7/18/2014 4:42:40 PM

Pros: Easy to use and worth the money. This is the best product to use when running on OSX (Apple MacBook), Super easy to use when running screen. Just plug in the device, open terminal and run screen. Thats it. Super easy and great.

Cons: None

Overall Review: It would be even better if the product came with a spare USB extension, But thats just getting picky. you can pick up and extension for 5 bucks off new egg.

Awesome 7/5/2014 3:24:37 PM

Pros: Plug and play on Windows 7/8, FreeBSD and my Linux systems I tried it work.

Drivers included on CD were older than the drivers provided by even Windows update, which is a good sign because that means Trendnet is still updating drivers for the device.

Speed test on the device gave me a full 5.8 Mbps

Decently long USB cable allows you to plug it in at the rear of a tower and have the serial port at the front

Cons: Doesn't make salad or something like that.

Honestly, there's none. The device is PnP on a good dozen operating systems and it works.

Overall Review: I should have bought 2

Pros: Plug and play no matter the version of Windows. It is very difficult to find that in this type of device.

Cons: I can't think of one. Reliable.

Baud Problems 12/1/2012 1:39:36 AM

Pros: It worked fine for serial mice

Cons: Assuming that it wasn't horribly mangling my 57600 baud connection wasted several hours.

The driver certainly didn't help dissuade me from this obviously flawed assumption; it even implied that it could handle higher bauds.

Does exactly what I wanted it to! 6/13/2012 8:23:01 AM

Pros: Adds another serial port to a PC.
Works exactly like it's supposed to!

Cons: none

Overall Review: I bought this coverter to add a seconds serial port to my PC for troubleshooting networking equipment. I installed the XP drivers, plugged in the cable and both HyperTerminal and Putty work great with this cable. No problems at all. Yay! The cable I got was white, for those of you who are really expecting a blue one, just a FYI

Works great with ESXi 3/31/2012 10:44:19 PM

Pros: Great solution to add a serial port to VMs running under VMWare EXSi 5. VMWare doesn't like add in serial port cards, but this works great.

Cons: None.
