client_timeout.cpp

/*
   client_timeout.cpp

   Test client for the tcpsockets classes. Use this program to test connect
   and receive time out capabilties.  Start the server_pause on one port and
   the server_timeout on the other.  Then run client_timeout specifying the
   server_pause and server_timeout ports.  The client will time out trying
   to connect to server_pause, which never accepts connections.  The client
   will then time out waiting for a reply from server_timeout which never 
   replies to clients.
