heartBeat
With this command, it is possible to check whether or not the connection is interrupted (e.g.
wire break) or whether the reader is out of operation (e.g. network failure).
After executing the command, the reader blocks connection requests of new clients for 30
seconds. By periodically sending "heartBeat" commands within a period of 30 seconds, you
can make sure that no other unwanted user applications access the reader.
