State Definition Recovery
24 STOPPED An application issued a STOP OPERATION request. All
stations are now DEAD and all pending requests aborted.
To recover, make the requests described in
“Starting the Link” in Section 4, “Writing
Applications That Use ADCCP.”
25 Request-
specific
An application issued a MODE SET request to this station
or received a mode setting command from the remote
station. Pending data transfers for the station are
aborted. The new station state and mode depend on the
MODE SET request; for example, a MODE SET SNRM
puts the station in ITS and Normal Response Mode.
Recovery from this condition is application-
dependent. The application may purposely
issue MODE SET to cancel requests.
26 Request-
specific
The remote primary station sent a mode-setting frame to
this station. Pending data transfers for the station are
aborted. The new station state and mode depend on
which mode-setting frame arrived.
Recovery from this condition is application-
dependent, and recovery probably requires
waiting for an action from the primary station.
27 READY/DISC A request failed, even after the allowed number of retries.
The state of the station is unchanged. This error is
typically reported in connection with a MODE SET DISC
request.
Try the request again. The problem is with
the other station.
28 DISC A request failed, even after the allowed number of retries.
The station is DEAD and in ERRORSTOP condition.
You can use CHANGELIST to revive the
station, but probably should not until you have
checked the station for a possible
malfunction. It is also possible that
L2RETRIES should have a greater value.
29 Request-
specific
A new request replaced the one in progress. None. This is a warning.
30 DISC RNR condition lasted too long. Application dependent.
31 DISC SENDTEXT received as a response and No_RNR_Retry
option selected or No_SRNR_Retry is selected and the
local sent an RNR.
Application dependent.
