19.6. Phase Sequencing

In this section the possible SCSI-bus phase sequences
during execution of the command are described. Section
3.2.1 has more details about the generic phases in the
brackets.
:= <initiator-part> <message-out> <command> <disconnect> <reconnect>
<completed>
This sequence will be used for a READ BUFFER command
specifying a zero transfer length.
:= <initiator-part> <message-out> <command> <disconnect>
{<reconnect><data-in> <disconnect>} <reconnect> <completed>
This sequence will be used for the READ BUFFER with
transfer length greater than 0.
:= <initiator-part> <message-out> <command> <completed>
This sequence will be used for a READ BUFFER command
specifying a zero transfer length when disconnection is
not allowed.
:= <initiator-part> <message-out> <command> <data-in> <completed>
This sequence will be used for the READ BUFFER with
transfer length greater than 0 and disconnection is not
allowed.
