6-5
INITSTATUS
INITSTATUS
The INITSTATUS attribute specifies the initial IBM status that will be used to determine
the response when the subdevice is selected but not opened or connected. Refer to
Appendix G in this manual for more information about device status.
Note: This is a TR3271 attribute.
Default: 0
Range: 0, %177776, %177777, or any 16-bit octal value other than
0, %177776, or %177777
Objects: Lines
Profile Equivalent: INITSTATUS
status = 0 TR3271 responds to SELECTs with a WACK. A WACK
indicates that TR3271 is busy. The busy condition
prevails until either the application issues an OPEN
request to the addressed PTP subdevice or a
CONNECT command is issued. When a CONNECT
command is issued, a possible problem may be that the
host front-end might continue to send SELECTs in
response to the WACKs.
status =
%177776
TR3271 does not respond to SELECTs. As a result, the
host will time-out the subdevice (if the addressed
subdevice has not been opened or connected).
status =
%177777
TR3271 responds to SELECTs with an ACK0. Data from
the host is acknowledged but discarded because it was
not requested. A message containing the TR3271 line
handler's logical device number (LDEV) and the affected
device's subdevice number is logged to the operator
console.
This value is useful only if non-essential data such as
unsolicited informational messages can be sent to the
device before it is opened and connected.
