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 a sequence of DLE ACK and IDs from the

receiving station, it sends a transmission block containing the data texts as shown

below. Upon receipt of a sequence of DLE ACK and IDs in response to the last

transmission block (data text n), the sending station shifts to phase 3.

If a transmission message contains no data text, the sending station transmits the

heading text only.
