4. Old Business
4.1 SAS 1.1, adding the Terminate Data Transfer protocol service (03-245r4)
[Evans]

Mark Evans requested that discussion of this topic be deferred to the next

4.3 SAS-1.1: Close Port Selector Detection Gap (04-029r1) [Sheffield]
Bob Sheffield presented a proposal to use a new BROADCAST(CHANGE) primitive to
interlock handling of port selectors and a new LINK RATE NOT NEGOTIATED value
for the NEGOTIATED PHYSICAL LINK RATE field in the DISCOVER Response to
establish positive reporting of port selector presence.
Concerns were raised about definition of the proposed 4h negotiated physical
link rate code value. The balance between dealing with normal link rate
negotiations and the requirements for supporting the inactive side of a port
selector required careful consideration of the definition.
Bob agreed to prepare a new revision of the proposal for consideration at the
next meeting.
