Bits < b5 b4 b3 b2 b1 b0 > are described in Table 4-15.
Binary Frame Response (BFR = 0x01)
BFR commands are used to send decoded bar code data/RFID tag data to the host
(ASCII characters and binary data). Each byte has a value of between 0 and 255.
To avoid desynchonization, proprietary data link escape (DLE) encoding is applied if
the following values are encountered in the formatted frame (not including the STX/
ETX delimiters):
STX/ETX (0x7F), DLE (0xEE)
1.
The proprietary character (0xEE) is inserted before the ambiguous character is
inserted.
2.
The value of the ambiguous character is increased by 1.
Note:
This method simplifies the delimiter localization processing because the
ambiguous character cannot be mistaken for a delimiter.
