Looking for a front end to manage Arduino data from a PC.  
I Know the arduino side (Serial IO and parsing), looking for a PC side option.  
The need is to read data from the arduino, make changes, and write updated data back to arduino.  
Actual task is managing EEE memory configuration data.

Looking for examples of user interaction, such as creating entry form with text display and input, pick lists, etc.
