BCC verification online calculation

1. In computer science and network communications, BCC (Block Check Character) is an error detection method.

2. BCC is commonly used in serial communication to ensure the integrity of data blocks.

3. The BCC algorithm works by performing an XOR operation on each byte of data (typically two hexadecimal characters) to generate the checksum.

4. The method of calculating BCC may vary depending on the specific protocol or application scenario.
