Does everything you need to troubleshoot serial interfaces

If you have ever troubleshot serial communications between devices and not used a protocol analyzer, you should try this. Combined with a breakout box they tell you everything that is happening. They make a huge difference, and this does all you need. It was tested by me and worked with XP and 2 cheap USB to 9 pin serial cable adapters you can find anywhere. I tested in the single port passive monitor setup, 2 port passive monitor setup, and the NT mode which allows you to monitor a port in use on the same PC. All worked fine. The interface was very easy to use, set up, and follow.
