■ Abnormal termination of phase 2 (Abort of phase 2)

If the sending station receives no sequence of DLE ACK and IDs from the receiving

station after sending a sequence of DLE ENQ and IDs 59 times in succession, it

sends a sequence of DLE EOT and IDs to the receiving station after 0.5 second from

the 59th sequence of DLE ENQ and IDs and then aborts this transmission abnor-

mally.

Phase 3: Release of Data Link■ Normal phase 3

The sending station transmits a sequence of DLE EOT and IDs to the receiving

station. Upon receipt of a sequence of DLE ACK and IDs from the receiving station,

the sending station terminates the message transmission normally and releases

the data link.
