Hello Kishore...
If BREAK_REPLAY method is not enabled, then there is not a response from the
Idle state.... this very intentional.
Please refer to proposals 05-040, 05-086, 05-093, 05-145, and 06-119 for the
various issues regarding potential BREAK race conditions.

Subject: Clarification regarding response to BREAK received in IDLE state.
All
I am referring to sas 2r14d. This state describes what needs to be done if
BREAK is received when in Idle state. Does this mean that we respond to BREAK
received in idle state only if BREAK_REPLY method of responding is enabled
and if BREAK_REPLY method of responding is disabled, we don't respond at all
(basically ignore the received BREAK and let the transmitter of BREAK
timeout)
OR
Was it supposed to mean the following:
?	We respond to BREAK with BREAK_REPLY (if BREAK_REPLY method is
enabled)
?	We respond to BREAK with BREAK (if BREAK_REPLY method is disabled)
The question can be generalized to anywhere such text is given. How should it
be interpreted?
Text from the sas standard rev 2r14d
7.15.4.2 SL_CC0:Idle state
7.15.4.2.1 State description
If a BREAK Received message is received and the BREAK_REPLY method of
responding to received
BREAK primitive sequences is enabled (see 7.13.5), then this state shall send
a Transmit BREAK_REPLY
message to the SL transmitter.
Thanks
