If AcquireSleep is set to On, any tags read by auto mode or interactive mode will
be put to sleep as they are found. Subsequent reads of the tag field will return no

If AcquireSleep is set to Off, tags will be left awake once they have been read.
Thus repeated reads will return the same tag IDs.

If AcquireWakeCount is set to zero or less, no Wake commands will be issued.
