  • Page 196 Data transmission may accidentally involve various types of errors. The BHT-protocol is designed to recover from those errors as frequently as possible. What follows is the BHT-protocol for phases 1 through 3. Phase 1: Establishment of Data Link Normal phase 1 The sending station transmits an ENQ to the receiving station.
  • Page 197 Appendices Abnormal termination of phase 1 (Abort of phase 1) If the sending station receives no ACK from the receiving station after sending an ENQ 10 times in succession, it sends an EOT to the receiving station after three seconds from the 10th ENQ to terminate the message transmission abnormally. Sending Receiving station...
  • Page 198 Phase 2: Data Transmission Normal phase 2 The sending station first sends a transmission block containing the heading text. Each time the sending station receives an ACK from the receiving station, it sends a transmission block containing the data texts as shown below. Upon receipt of an ACK in response to the last transmission block (data text n), the sending station shifts to phase 3.
  • Page 199 Appendices Phase 2 with NAK If the sending station receives a NAK from the receiving station in response to a transmission block containing text data m, it sends that transmission block again immediately as shown below. If the sending station receives an ACK before receiving a NAK 10 times in succes- sion, it continues the subsequent message transmission.

    Appendices [ 2 ] Aborting Data Transmission Pressing the C key aborts data transmission. If the C key is pressed during downloading, the BHT transmits an EOT and aborts the file transmission. If it is pressed during uploading, the BHT transmits the current transmission block followed by EOT and then aborts the file transmission.

    [ 3 ] BCC for Horizontal Parity Checking To check whether data has been transmitted accurately, the BHT supports horizontal parity checking for every transmission block. In horizontal parity checking, a horizontal parity byte so called BCC (Block Check Character) is suffixed to an ETX of every transmission block. In the BHT-protocol, every parity bit of BCC is set so that all set bits at the same bit level (including a parity bit) in the characters contained in the transmission block have an even number by binary addition, excluding SOH, STX, and functions SOH$ and...
