   NOTE : it has been measured that the longest barcode the CueCat can send is
          a CODE128-B of 19 characters (that can all be uppercase) or a
          CODE128-C of 38 digits. In the first case, 19 characters are coded on
          26 coded triplet characters, i.e. 4*26=104 scancodes if all of them
          are uppercase. In the second case, 38 digits are coded on 51 coded
          triplet characters, i.e. 4*51=204 scancodes if all of them are upper-
          case. So the longest barcode will be sent with 204 scancodes.
