(1): The default minimal length is 6 characters for all symbologies.
(2): This option will not have any effect on symbologies requiring a checksum calculation (EAN/UPC, Code128). Concerning the symbologies that allow two check digits (code93, code11), the first check digit is obligatory. Thus, this option will affect the calculation/non calculation of the second check digit.
(3): The default maximal length is 32 characters for all symbologies.
2.4.5.4.Special Commands (Type "E")
Some commands require more than a Boolean digit and require one or more arguments.
Special commands will be used in this case (defined code "E" in type field). It is made of one byte corresponding to the type of command. Then, depending on the type of command, a certain number of parameters will be expected. Each of these will be 1 byte long.
This type of command allows the sending of multiple commands in one frame. The Size field must then specify the total length, in bytes, of the command field.
