DTS EtherSAM test application, depending on the active test on the
local module.
If a remote module is in any busy status a user confirmation is
required to proceed with the Loop Up command.
Following a successful connection, the IP address of the remote
module will be used as the destination IP address for the test.

DTS Disconnect ends the connection between the local and the
remote modules.
