Beginning a new session connects to the server. Before opening
a new session, make sure no other session is open that could
block the LCA. Then you have the right to control the LCA.
When you select “open a session”, the program sets the
instances of LCARemoteClient, LCAMeasParams and
LCAProperties. The program then sets the IP address variable
and makes it available to the other parts of the program.
