1 word DOID Destination/Origin
ID assigned by the
subsystem
QUERY
This bit must be set to Binary 1 for all IBM auxiliary devices to indicate that it
supports receiving a Read Partition (Query, Query List). The host application
may then use a Read Partition directed to the auxiliary device to determine its
characteristics. The destination/origin structured field is used to direct the Read
Partition structured field to the auxiliary device.
The minimum support level for the IBM auxiliary device is to return the Null
Query Reply in response to the Read Partition.
LIMIN
States the maximum number of bytes that can be sent in an inbound
transmission. A LIMIN value of X'0000' indicates no implementation limit on
the number of bytes transmitted inbound.
LIMOUT
States the maximum number of bytes that can be sent to the IBM auxiliary
device in an outbound transmission. A LIMOUT value of 0x0000 indicates no
implementation limit on the number of bytes transmitted outbound.
TYPE
Identifies the auxiliary device being supported. Two values are valid. One
identifies an auxiliary display and the other identifies an auxiliary printer. All
other values are reserved.
The IBM auxiliary device processor supports two Self-Defining Parameters, 01
and 03. These are defined in Table D-7.
