45*
46* \brief Base Class for host side remote controls that talks to target side
47*through ethernet connection
48*
49* There are 3 communication channels:
50* - 1 connection with the ground station to display the values. Output for
51*analog sticks is normalized in the range [-1, 1] (float values) (through DrawUserInterface, use a UDT socket)
52* - 1 connection with the target to send the controller values (through udp socket - high bandwitdh, packets may be discarded)
53* - 1 connection with the target to receive controller state modification requests (through tcp socket - low bandwidth, packets must not be discarded)
