How i can send a system message to a player that i cant be seen by other players?
                
            /msg message
struct MsgToConn // 64 chars - send to LFS and on to a chosen connection (0 = host)
{
	char	Id	[4];	// MTC + zero
	byte	Conn;		// connection
	byte	UniqueId;	// destination player UniqueId : if set, Conn is ignored
	byte	Sp2;
	byte	Sp3;
	char	Msg	[64];	// text message or /command, must end with zero
};
