+In the next step NDT server is calculating if it can handle client request  
and client SHOULD expect at least one 'SRV_QUEUE' message. This message MAY  
contain one of the following values:
+
+|| *SRV_QUEUE value* || *Description* ||
+|| 0 || Test session will start now ||
+|| 9977 || Server Fault: test session will be terminated for unknown  
reason. Client SHOULD drop the connection after receiving this message.  
*Not used currently by the server* ||
+|| 9988 || If this is a first message from server, then it means that  
server is busy. In other cases it means Server Fault. Client SHOULD drop  
the connection after receiving this message. ||
+|| 9999 || Server Busy: Please wait 60 seconds for the current test to  
finish. Client SHOULD drop the connection after receiving this message.  
*Deprecated/Not used by the server* ||
+|| 9990 || This is a check from server to verify if the client is alive.  
Available from v3.5.5. The client SHOULD respond to this message by  
sending 'MSG_WAITING' empty message. ||
+|| N || Where N is any other value. It means the estimated number of  
minutes that client will wait for its test to begin. ||
