7.3 Operation of SECS Protocol
If it receives an
<ENQ>
, it puts off sending its message, sends an
<EOT>
and then reads the other message.
When both the host and the equipment try to send at the same time, the
host must cancel its inquiry because the host is working in slave mode. It
must first receive the equipment message because the reader is the
master. Only then can the host send its message.
For more detailed information about all possible cases, see SEMI E4.
