The master Reader/Writer will communicate with the RF Tags through the "Once" communica-
tions option. Here, if the communications have ended normally, the communications results are
returned to the host device. If the communications results indicate an RF Tag missing error or a
communications failure, an error response is not returned to the host device, but if any other
error is detected, the error results are returned to the host device. The communications process-
ing will then progress to step 3.
