Named Values The following pages present named data values defined for use by application
programs when calling the APS procedures.
Note that an application will receive only those values applicable to the OSI layers it is
using.
ZAPS-VAL-ABORT-xxx indicates the reason a connection has been aborted by the
service provider. OSI/AS defines the following abort reason values:
CONSTANT ZAPS-VAL-ABORT-NOVALUE VALUE 0.
CONSTANT ZAPS-VAL-ABORT-TRANSPORTDISC VALUE 1.
CONSTANT ZAPS-VAL-ABORT-PROTOCOLERROR VALUE 2.
CONSTANT ZAPS-VAL-ABORT-NOREASON VALUE 3.
CONSTANT ZAPS-VAL-ABORT-PPDU-UNREC VALUE 4.
CONSTANT ZAPS-VAL-ABORT-PPDU-UNEXP VALUE 5.
CONSTANT ZAPS-VAL-ABORT-SPDU-UNEXP VALUE 6.
CONSTANT ZAPS-VAL-ABORT-PPDU-P-UNREC VALUE 7.
CONSTANT ZAPS-VAL-ABORT-PPDU-P-UNEXP VALUE 8.
CONSTANT ZAPS-VAL-ABORT-PPDU-P-BAD VALUE 9.
ZAPS-VAL-ABORT-NOVALUE shows that the parameter has no value.
ZAPS-VAL-ABORT-TRANSPORTDISC shows that the session service has reported a
transport disconnection. This value applies only to session connections.
ZAPS-VAL-ABORT-PROTOCOLERROR shows that the session service has reported a
protocol error. This value applies only to session connections.
ZAPS-VAL-ABORT-NOREASON shows that no reason has been given for the abort.
ZAPS-VAL-ABORT-PPDU-UNREC shows that a presentation protocol data unit
(PPDU) is unrecognized. This value applies only to presentation connections.
ZAPS-VAL-ABORT-PPDU-UNEXP shows that a PPDU is unexpected. This value
applies only to presentation connections.
ZAPS-VAL-ABORT-SPDU-UNEXP shows that a session service primitive is
unexpected. This value applies only to presentation connections.
ZAPS-VAL-ABORT-PPDU-P-UNREC shows that a PPDU parameter is unrecognized.
This value applies only to presentation connections.
ZAPS-VAL-ABORT-PPDU-P-UNEXP shows that a PPDU parameter is unexpected.
This value applies only to presentation connections.
ZAPS-VAL-ABORT-PPDU-P-BAD shows that a PPDU parameter is invalid. This
value applies only to presentation connections.
