After the connection has been established,
the user application communicates with the
reader.
It sends, for example, a heartbeat frame at
regular intervals.
④
For each command, the reader sends a
reply frame.
⑤
The user application sends the command
"hostGoodbye" to terminate the connection.
⑥

TCP/IP connection.
If commands are sent without being preceded by the "hostGreetings" command, the reader
replies with the error message "ERROR_INVALID_READER_STATUS".
