Appendix D LUNS High-Level Flow Diagrams
097841 Tandem Computers Incorporated D–1
This appendix contains flow diagrams showing logon and logoff sequences for:
A host application for which the ESS table specifies CMDTYPE LOGON-CHAR,
but not REPDATA
A host application for which the ESS table specifies CMDTYPE LOGON-CHAR
and REPDATA
A host application for which the ESS table specifies CMDTYPE LOGON-INIT
A host application for which the ESS table specifies CMDTYPE INITSELF-
RECEIVED
A static passthrough application
In the illustrations, the logon and logoff sequences flow counter-clockwise—that is,
from the terminal at the right, to LUNS, then to the various processes, and back again
to the terminal.
