■ Abnormal termination of phase 1 (Abort of phase 1)
If the sending station receives no sequence of DLE ACK and IDs from the receiving
station after sending a sequence of DLE ENQ and IDm 60 times in succession, it
sends a sequence of DLE EOT and IDm to the receiving station after 0.5 second
from the 60th sequence of DLE ENQ and IDm, then aborts the message transmis-
sion abnormally.
