ZLAST-SL-ERR-SOURCE
is the source of the last communications error detected by a TAPS process.
This field has meaning only if the value of ZLAST-SL-ERR is nonzero.
Possible values are as follows:
ZCOM-VAL-SERV-LEVEL-L5 Session Layer
ZCOM-VAL-SERV-LEVEL-L6 Presentation Layer
ZCOM-VAL-SERV-LEVEL-ACSE ACSE
ZL4-SUNAME
is the name of the Layer 4 (transport) subdevice that is providing transport
services for the specified TAPS subdevice, or in the case of an SU in loopback
mode, is the name of the remote connection endpoint TAPS SU, which resides
in the same TAPS process as the SU being displayed.
ZINITIATOR
is the initiator of the connection. If this field is set to ZSPI-VAL-TRUE, the
local system is the initiator; if it is set to ZSPI-VAL-FALSE, the remote system
is the initiator.
ZCALLING-ADDR
is a structure containing the calling OSI address for the specified subdevice.
This token has the following fields:
ZNAME-LEN
is the length (in bytes) of the calling application name. The range of
values is 0 through 128 bytes.
ZNAME
is the name of the calling application.
ZNSAP-LEN
is the length (in bytes) of the calling NSAP address in ZNSAP. The range
of values is 0 through 20 bytes.
ZNSAP
is the calling NSAP address for the specified subdevice. The NSAP
address is a binary-encoded string of an even number of hexadecimal
digits. NSAP addresses are administered by a central addressing
authority.
