Did you know that the Virtual Serial Ports that you can create using Smart SDR from Flex also work with your SunSDR2dx.

Do you mean you can use the SmartSDR Software with the SUN on a mac?

Whenever I use a mac, I use it to run windows

What I was saying, is that I use SmartSDR CAT to create virtual serial ports on my PC.
The virtual serial ports created with this Flex software also works on my SunSDR2dx running ESDR3 on my PC.

That's all!
