SerialIndex

The implementation of SerialIndex enables applications to update the value of a variable across platforms when change is detected. Here the value of a variable is linked through a text based protocol primarily used over serial communication but equally applicable to other forms of communication channels. The objective of this project is to automatically synchronize variables and their values across applications and platforms. At this point this is work in progress.
