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.
