DMT902E Non-signon card read on link linkid
Explanation
The link identified by linkid had not been signed on, and a record received from the remote station was not a SIGNON record, contrary to link operational requirements.
System action
If the link is an auto-answer link, it is deactivated and counts as an invalid signon toward its limit of 5. Otherwise, an MRJE-type link is deactivated; an RJE-type link remains active but not signed on, and file, command, and message exchange for the link remains suspended pending successful signon.
User response
Correct any errors present on the signon card, and try the signon procedure again.
