Has anyone successfully purchased a USB to serial adapter and used a null modem cable?

I'm looking at this one:

But hopefully there are some suggestions on known working ones =)

Thanks in advance!

oh, many people have! we use them all the time, and at our training classes - people also use them. different kinds and brands, just make sure there is a driver for your OS

I use them all the time...
Also on my Mac in OS X since it does not have a serial port...

If you need one fast, Radio Shack stocks them.

I see - my major concern was incompatibility of USB to serial adapters (as I have had some customers with medical devices that were picky about which products to use).

If all I have to worry about is a driver for my OS then that answers my question. Thanks for the help guys!
