| DESCRIPTION OF ENHANCEMENTS |
The test sites for Patch HL*1.6*75 are Bay Pines VAMC, Palo Alto VAMC,
back up, the option forces you to stop the process before you can re-
set to Shutdown, then the client logical link quits and the Link
Manager will not attempt to restart the Link. In this particular case,
the SHUTDOWN LLP field (#14) is set to YES in the HL LOGICAL LINKS
file.
The other condition in which the value Error gets stuffed in the STATE
field (#4) is when the client logical link gets an unexpected error. If
the client logical link encounters an error other than the expected
errors: OPENERR, NOTOPEN, DEVNOTOPN, WRITE, or READ, it logs the error
in the error trap and shuts down the client logical link.
enable it to continue the communication process.
In this case, the SHUTDOWN LLP field is set and the client logical link
has to be restarted manually.

Before this patch (Patch HL*1.6*75), using the option Start/Stop Links
to re-enable a client logical link in an Error STATE was a two-step
process. After this patch has been installed, using the option
Start/Stop Links to re-enable a client logical link in an Error STATE
will become a one-step process. However, this will only apply to client
logical links in which the SHUTDOWN LLP field is set to YES while in an
Error STATE. (See the following explanation "Description of What Causes
an Error State" for more information on Error States.)

Description of What Causes an Error State
=======================================================================
Error STATEs can be related to retransmissions. If the number of retry
attempts has been exceeded, an alert is sent and the word Error appears
in the STATE column on the System Link Monitor for that client logical
link. This relates to the EXCEED RE-TRANSMIT ACTION field (#200.021) in
the HL LOGICAL LINKS file. If the EXCEED RE-TRANSMIT ACTION field is
set to Restart, the client logical link quits and the Link Manager
queues (restarts) the link. If the EXCEED RE-TRANSMIT ACTION field is
