Sending a special command to Code39 symbology.

We now want set a larger frame of Min-Max length for Code39 symbology.

Frame to be sent to the decoder:

‘E’ ‘E’ 3 ‘C’ , 2 , 40

Command

Reading this frame, the decoder understands:

The user wants to send a special command (Type "E") to Code39 symbology (Header "E").

The size must be at least 2 and the first byte of the command field must contain a code (ACSII) that

will tell (indirectly) the number of parameters following.

The command "C" will first read, it means “setting a Min. length and a Max. length”. Then the usual

commands ‘D’ and ‘e’ will be sent to enable Min length and Max. length for Code 39 symbology.

Then the Min length will be set to 2 and the Max. length will be set to 40.
