Phase 3 with iterated transmission of DLE EOT and IDs due to no response 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, then 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, then 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, then it aborts the message transmission
abnormally and releases the data link.
