8.2.9.6
The receiver detects an abort sequence in the middle of the message payload. An abort sequence is defined as
any zero followed by 15 consecutive 1s.

Bit errors during transmission.
Incorrect message transmission from distant end.
When the message reaches the top of the internal FIFO, the entire HDLC message is copied to shared
memory buffers and the Buffer Status Descriptor is written (if INHRBSD = 0 in
with ONR = HOST, ERROR = ALIGN.
EOM Interrupt with RxALIGN error status, (if ERRIEN = 1 in
The RSLP scans for the opening flag of the next HDLC message.
RDMA is not affected and continues shared memory buffer processing.
None required.
Distant end failed to complete transmission of the HDLC message.
Path conditioning has replaced the normal channel content with an all ones pattern, due to a network alarm
condition.
When the message reaches the top of the internal FIFO, the entire HDLC message is copied to shared
memory buffers and the Buffer Status Descriptor is written (if INHRBSD = 0 in
with ONR = HOST, ERROR = ABT.
EOM Interrupt with RxABT error status, (if ERRIEN = 1 in
The RSLP scans for the opening flag of the next HDLC message.
RDMA is not affected and continues shared memory buffer processing.
None required.
Incorrect message transmission from distant end.
