# Script to emulate an instrument sending UDP packets to RIC.

#

# If you would like to test the complete path from the aircraft, but the

# instrument is unavailable, use this script.

#

# Change the ip and ports and message ID (they need to match what is in the

# <inst>.ini file). Change the content of the message to whatever is useful

# to you.

# Then run it to write a message to the specified port, which should be sent

# via ric_switch to the proxy on the ground.

#

# This script can also be a reference for instrument code in Python.
