EADING
Here a forklift will cause an electric eye to send a signal to the reader. We want
the reader to look for a rising edge on this signal and scan for tags for 1.8
seconds before going back to the Waiting state. We won't make any changes to
the output pins.

OTIFICATION
A trigger is used to start the reading. If a tag is found, send an email message.
After the email is sent, return to the waiting state.

Notification Mode
The last stage in configuring the Autonomous Mode is to tell the reader under
what conditions to notify listeners about TagLists. Listeners (network applications
/ people) are notified only when specific conditions arise, such as when new tags
are read, or when tags disappear from view.
Note: Notification Mode is not supported on the ALR-9770 reader at this time.
NotifyTime
The NotifyTime command instructs the reader to send out a copy of its
TagList to a listener every
n seconds, regardless of whether the TagList has
changed or not. This is a simple way to force the reader to send out its
TagList to a listener.
