    3.3.3 Basic Format of Transmission Messages Basically, the BHT-4000 transmits data as a unit of a file. First, it transmits a heading text which includes the attribute information of a file (e.g. file name and the number of data texts) to be transmitted. Following the heading text, it transmits the data text in the file.

  • Page 96 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 97 Chapter 3. Communications Operations of BHT-4000 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.
  • Page 98 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.
