For example you can create a test.crb file that contains commands to enable Aztec symbology
and make the reader beep three times. Note you can also comment your CRB file with a
semicolon (;) as shown below.
NOTE: The only command which is not ignored in the CRB file when a semicolon
(;) is used is ;>PA7. In all other cases anything that follows the semicolon is
commented out.
Example: test1.crb
;>PA7 ;enable programming mode
P%501 ;enable aztec symbology
#%03 ;beep reader 3 times
~ ;save the settings
PA8 ;disable the programming mode
