Excellent product! 11/13/2014 10:34:24 AM

Pros: Just works. Good price and free shipping, which came fairly quickly.

Cons: none.

Overall Review: I purchased this to be able to test some legacy serial equipment on my company laptop that doesn' have a serial port. Installation was a snap. We have 4 different peices of equipment and all the connections worked perfectly including hyperterminaling into a 3COM managed switch. I highly recommend this adapter. As soon as my manager gives me th go ahead, i am sending a link to my fellow techs so they can get one also.

Works Like a Charm 4/9/2014 1:29:40 PM

Pros: This adapter was immediately recognized and installed by my Win7 x64 system, and I was able to communicate through the COM port successfully.

Cons: None so far.

Overall Review: An installation CD was included, but I didn't need it.

I was successfully able to make my new Win7 x64 system output to a 25+ year-old HP 7475A pen plotter!

Great product! 12/11/2013 9:30:25 AM

Pros: Fast, does not interfere with software, saves port assignments

Cons: Little larger than it needs to be. Purely cosmetic complaint, we really don't care.

Overall Review: We run a small business that must have serial port printers. We had been using a Belkin cable, which we didn't even know was interfering with our point of sale system (we blamed our new HP computers). When one finally died, we ordered this cable - and are thrilled. It solved compatibility issues that we didn't even know came from the cable, and now our system runs faster and more reliably. Great buy! Yes, the housing is a little larger than it needs to be - but we could care less. We were so pleased with the first that we ordered another, and are now ordering one more so all our computers will use this cable. Would definitely recommend.

Works in win7 12/4/2013 6:40:23 PM

Pros: Painless to install since you do not need to crack open the machine, connects to USB port. Software installed without any problems.

Cons: Don't waste your time on cheaper devices, buy only ones confirmed to work with your operating system.
