Serial over wifi
I have made my own solutions for this but it is great to see a cheap product that can do this. It is bi directional and has a variety of adaptors and cheap. They make a driver that creates a virtual comport so you dont have to change anything in your setup if you are using serial, just switch it to the new virtual comport and connect.Fredhttp://www.get-console.com/airconsole/
Thanks Fred, this is cool.
I found this line relatively frightening however:
"Great for industrial use such as controlling robots directly from a mobile webpage"
