COMMANDS AND RESPONSES
INFO Command
ZTR3-MAP-INFO-SU is the extensible structured token that lists
the current values of the configurable attributes for a subde-
vice. It has the token number ZTR3-TNM-INFO-SU and the DDL
definition ZTR3-DDL-INFO-SU. This token must be in the response
when the specified object is ZCOM-OBJ-SU or the LINE object has
been specified with the subordinate modifier with the value ZCOM-
VAL-SUB-ALL or ZCOM-VAL-SUB-ONLY. Duplicate occurrences of these
fields are not allowed.
Each attribute is listed in a separate field. The fields in the
ZTR3-MAP-INFO-SU token are as follows:
ZADDR A pair of integers that specifies the address
assigned to the subdevice. The first integer
is the address of the control unit. The second
integer is the address of the subdevice. Both
integers should be in the range 0 through 31.
ZPROTO An enumerated value that specifies the protocol
used by the subdevice. There is no default value.
It can have one of the following values:
ZTR3-VAL-PROTO-CRT The CRT protocol is used.
ZTR3-VAL-PROTO-PTP The pass-through protocol
(PTP) is used.
ZRECSIZE An integer that specifies the maximum number of
bytes the subdevice can send or receive in a
record. The recommended record size depends on the
protocol used and the type of subdevice as follows:
CRT terminal The defined screen size is used
as the record size.
PTP subdevice The defined screen size is as
follows:
Screen Size
Record Size
480 512
960 1024
1920 2048
