> If there is a rev to SAS, here is another error:
> Conflict text to figure:
> doc page 122, Section 126.96.36.199.3 Transition SP2:OOB_NoCOMSATimeout to
> states "This transition shall occur after receiving a COMINIT Detected
> doc page 121 Figure 67 shows the SP2:OOB_NoCOMSASTimeout
> state tranitioning
> to SP4 (rather than SP3) when COMINIT Detected message is received.
> Note: This is not the case illustrated in figure 66. In that case the
> timeout occurred on COMINIT. Here the timeout is on COMSAS.
> A transition to SP3:OOB_AwaitCOMINIT_Sent will result in a hang as
> Transmit COMINIT only occurs in SP0: COMINIT and a COMINIT Transmitted
> confirmation is need to exit SP3:OOB_AwaitCOMINIT_Sent.
> A transition to SP4:OOB_COMSAS is a problem for the attached
> phy. It may have completed a Hot-plug timeout and transitioned
> to SP0: COMINIT. A COMINIT Detected confirmation is required to exit
> Suggested Fix:
> Change 188.8.131.52.3 to:
> "Transition SP2:OOB_NoCOMSATimeout to SP0:OOB_COMINIT"
> Change figure to reflect this change:
> Delete arrow SP2 to SP4,
> Add arrow SP2 to SP0 with COMINIT Detected.
