zx25d 439 Link <#>: Write request (type = <#>) failed with error <#>!
Virtual Circuit will be reset or cleared.
Explanation: The buffer completion status for a zsend request to the
specified ZLU has unexpectedly failed due to the
indicated error. This routine is used to send X.25
protocol packets on the link. For example, sending a
clear packet in response to any packet received on an
unassigned logical channel. It is possible for this
failure to occur under normal conditions such as a link
disconnect right as the zsend is being issued. The type
parameter in the message indicates the type of protocol
packet being sent as follows:
type 14 = Restart Confirmed packet
type 19 = Clear/Reset for abnormal packet
type 20 = Enable PVC
type 21 = Call Accepted packet
type 22 = Reply to application request (e.g. zx25... call)
type 24 = Diagnostic Packet
Action: Check the error returned against those listed in this
guide and take corrective action as necessary. If the
problem persists and you are unable to determine its
cause or the error code indicates a probable internal
defect, contact your HP support representative.
