COMMANDS AND RESPONSES
INFO Command
ZCTL-SET An enumerated value that specifies the bisyn-
chronous control set. The value ZTR3-VAL-CTL-
SET-ASCII indicates that the ASCII control set
will be used. The value ZTR3-VAL-CTL-SET-EBCDIC
indicates that the EBCDIC control set will be
used. The default value is ZTR3-VAL-CTL-SET-
EBCDIC.
ZDEBUG A Boolean variable that enables the CLIP DEBUG
interface. If the value is ZSPI-VAL-TRUE, the
interface is enabled. If the value is ZSPI-VAL-
FALSE, the interface is not enabled. The default
value is ZSPI-VAL-FALSE.
ZDROP-RTS A Boolean variable that specifies whether the
Request To Send (RTS) signal is dropped when
the software switches from a write operation to
a read operation. If the value is ZSPI-VAL-
TRUE, the signal will be dropped when switching
operations. If the value is ZSPI-VAL-FALSE, the
RTS signal will not be dropped. The default
value is ZSPI-VAL-FALSE.
ZINIT-STATUS A 32-bit integer that specifies the initial IBM
status that the TR3271 subsystem returns when it
receives a SELECT for a subdevice that has not
been OPENed or CONNECTed. The possible values
are:
0 The TR3271 subsystem responds with
a wait for acknowledgement (WACK)
indicating that the subdevice
is busy. The subdevice remains busy
until an application OPENs or
CONNECTs the subdevice. Note that
this can have a cyclic effect; the
host front-end might resend a SELECT
each time it receives a WACK from
the TR3271 subsystem.
%177776 The TR3271 subsystem does not
respond to SELECTs. Consequently,
the host times out the subdevice
provided the subdevice has not been
OPENed or CONNECTed before the
timeout period elapses.
