EXAMPLE #3:
The following example shows the events that occur when an invalid bar code
is sent. This sample will load the factory default settings and then set the
baud rate to 19200.
FEATURE
Enter Configuration Mode
Load Defaults
Invalid command was sent, you must start over!
Enter Configuration Mode
Load Defaults
19200 Baud Rate
Exit Configuration Mode
The scanner will beep three times!
This example illustrates two important points.
First, if an invalid command is sent from the host, the scanner responds with
a [nak] and the end-user must start over from the beginning.
Second, if a command is sent to change the Baud Rate, the new baud rate
does not take effect until after the end-user exits configuration mode.
