The Basic Link Services supported by this drive are the Abort Sequence (ABTS)
and its responses, Basic Accept (BA_ACC) or Basic Reject (BA_RJT). Other
Basic Link Services are discarded.
The header field of the basic link service is defined in Figure 1.17.
Figure 1.17 Header field of the basic link service
(1) R_CTL.. (Routing Control)
The high order four bits (8h) represent Basic Link Service, and the low order
four bits each Basic Link Service.
(2) D_ID.. (Destination Identifier)
− Address of the drive which receives ABTS.
− Address of the initiator for a response to ABTS.
(3) S_ID.. (Source Identifier)
− Address of the initiator which sends ABTS.
− Address of the drive for a response to ABTS.
(4) Type
The Basic Link Service uses 00h.
(5) F_CTL.. (Frame Control)
− Set 090000h for the transmission of ABTS.
(Originator of Exchange, Last Data Frame of Sequence, Transfer
Sequence Initiative)
− Set 990000h for a response to ABTS.
