[telles_s]

Localhost communication is one way to exchange data between NI Linux RT and LabVIEW RT code. Below, is a Shell Script and LabVIEW project that exemplifies NI Linux RT command line interface sending/receiving data to/from LabVIEW RT through TCP socket.

Steps to execute:

     1. Copy the waveform script to a NI Linux RT diretory
