STATUS
Transport Virtual Circuit
state
The current state of the connection. Only the low order nibble is significant, with
these possible values:
Value
State
Description
0
Listen
The local node is waiting for an incoming connection request
from a remote node.
1
CrSent
The local node transmitted a connection request and is
waiting for connection confirmation from the remote node.
2
AckWait A listening node received a connection request, sent its
confirmation, and is now awaiting the completion of the 3way handshake.
3
Estab
The connection is established and in the data transfer phase.
4
Closing
The application initiated a disconnect of the VC; the node is
awaiting confirmation of the disconnect request from the
remote node.
5
Closed
The CDB is closed to communication, but has not been
released, pending an application request block to give
notification of the format status of the connection.
6
Open
The CDB was allocated using an OPEN command, but no
subsequent requests have been made on this connection.
7
Calling
A transient internal state that should be ignored.
8
CrRcvd
A listening node received a connection request and sent an
indication to the client by returning an
AWAIT_CONNECT_REQUEST_CLIENT request block;
the connection is awaiting the response.
9
RefWait
The connection is closed, but the reference is being timed out
before the CDB is deleted.
loc_ref
The connection reference maintained by the local station. This is the value specified
in the reference field of request blocks associated with the connection.
rem_ref
The connection reference maintained by the remote station. During the lifetime of
the connection, the two connected nodes identify the connection for each other using
this and the loc_ref value.
persist
The connection refusal persistence_count used by the connection.
abort_to_hi
The high-order word of the 32-bit abort timeout value used by the connection.
retran_to_dw
