Commands may be strung together to create custom response sequences. An
example of a command string is listed below.

0456,

The above example will make an image scanner in application work group zero
beep low, medium, high.

Once Host ACK is enabled, the system works as follows:

The image scanner reads a code and sends data to the base/host system. No
audible or visual indication is emitted until you receive an escape command.
The image scanner read illumination goes out upon a successful read.

Image Scanner is suspended until 1) a valid escape string is received from the
host system (via the base) or 2) the image scanner “times out.”

Once condition 1 or 2 above has been met, the image scanner is ready to
scan again, and the process repeats.

Time out is indicated by three rapid beeps at the same pitch. A time out occurs
if the source image scanner does not receive a valid escape command in 10
seconds. If a time out occurs, the operator should check the host system to
understand why a response to the image scanner was not received.
