This example implements an IHE LAB-62 transaction.
A simple MLLP server accepts QPB_Q11 messages only, returning a NAK message otherwise.

server.py: MLLP server and LIP implementation. The TCP server binds by default to localhost:6000.
client.py: TCP client and LB implementation. It sends the QBP_Q11 message to localhost:6000.

=== HOW TO USE ===

Run the TCP server by executing:

python server.py

then execute the client:

python client.py
