multiple bit errors that may occur during transmission and reception of 
information. In addition, some of the control characters of the transmission code

The link reset sequence consists of the phy reset sequence and the identification 
sequence.  The phy reset sequence consists of the out of band (OOB) sequence 
and speed negotiation sequence.  The hard reset sequence is performed only when 
the HARD_RESET primitive is detected after the completion of the speed 
negotiation.  The HARD_RESET primitive detected at any time later than the 
identification sequence is invalid.  The hard reset sequence corresponds to the 
reset condition of pSCSI.
