The BHT supports seven types of bar codes--the universal product codes, Interleaved 2 of
5 (ITF), Standard 2 of 5 (STF), Codabar (NW-7), Code 39, Code 93, and Code 128. The
BHT can read also EAN-128 if Code 128 is specified.
(For readable bar code types, refer to the BHT User’s Manual.)

EAN-13, UPC-A
B
EAN-8
C
UPC-E
If code is omitted, the default is all of the universal product codes.
1stchara and 2ndchara are flag characters representing a country code and should
be numerals from 0 to 9. If a question mark (?) is specified to 1stchara or 2ndchara,
it acts as a wild card.
supplemental is a supplemental code. Specifying an S to supplemental allows
the BHT to read also supplemental codes.
