■ Phase 3 with iterated transmission of DLE EOT and IDs due to no re-
sponse or invalid response
If the sending station receives no response or any invalid response from the
receiving station in response to the sent sequence of DLE EOT and IDs, it iterates
sending of the sequence at 0.5-second intervals up to 60 times.
If the sending station receives a sequence of DLE ACK and IDs before sending the
sequence of DLE EOT and IDs 60 times, it terminates the message transmission
normally and releases the data link.
■ Abnormal termination of phase 3
If the sending station receives no sequence of DLE ACK and IDs from the receiving
station within 0.5 second from the 60th sequence of DLE EOT and IDs, it aborts the
message transmission abnormally and releases the data link.
