Block Check Character
  • A character added at the end of a message or transmission block to facilitate error detection. Note: In longitudinal redundancy checking and cyclic redundancy checking, a block check character is transmitted by the sender after each message block. This block check character is compared with a second block check character computed by the receiver to determine if the transmission is error free. See also block check, block parity, character, cyclic redundancy check, error control.
