Looks like an R message permit the cube to reboot:

This is not a generic command that you can issue in a telnet session.
This is command is packed in a message to the UDP port instead. Like type of discovery packet

how can i send a message to the cube to get the answer ?

This is the data (19 Byte) one must broadcast or multicast to UDP port 23272 to get an answer from the cube.

You need to send that as a udp message to the cube. To do this you would usually use a networking library for the language you are using. I have also seen netcat used to do this from the command line; there are several pages out there that show how to do it.
