ECO KIT SUMMARY:

An ECO (patch) kit exists for LAT on OpenVMS VAX V5.4 through V5.5-2[H4].
This kit addresses the following problems:

   o  OpenVMS VAX does not recognize any speed above 38400  kbps  and
      will  report  a  terminal  speed  of  0 if set to 57600 kbps on
      terminal server.

   o  If a system manager  creates  several  services  (sometimes  in
      excess  of  20  LAT  services)  on an OpenVMS VAX system, it is
      possible that the system may crash if the resulting LAT Service
      Announcement message is between 1488 and 1500 bytes in size.

   o  If the LAT node state is set  to  "shut",  OpenVMS  will  still
      allow  new incoming connections.  This is incorrect behavior as
      the LATCP documentation states that  the  "shut"  state  allows
      existing  connections  to  continue  and  operate  but  no  new
      connections are allowed.

   o  If a system manager  creates  several  services  (sometimes  in
      excess  of  20  LAT  services)  on an OpenVMS VAX system, it is
      possible that the system may crash if the resulting LAT Service
      Announcement message is between 1488 and 1500 bytes in size.

   o  If the LAT node state is set  to  "shut",  OpenVMS  will  still
      allow  new incoming connections.  This is incorrect behavior as
      the LATCP documentation states that  the  "shut"  state  allows
      existing  connections  to  continue  and  operate  but  no  new
      connections are allowed.

   o  If a user program issues a POSIX selective cancel operation for
      an OpenVMS VAX LAT device, this operation will return "function
      not supported".

  V3.5 addressed:

   o  During the execution of the LATCP CREATE LINK /DECNET
      command, the following error might be returned:

         %SYSTEM-F-BADPARAM, bad parameter value

      Another possibility is that there would be no LINK present as
      indicated by the LATCP SHOW LINK command returning the
      following error:

         %LAT-W-CMDERROR, error reported by command executor
         -SYSTEM-W-NOMOREDEV, no more devices

   o  When the LAT protocol is started on a FDDI controller, the
      datalink address associated will not be the DECnet Phase IV
      address of AA-00-04-00-nn-nn.  Instead it will be the hardware
      controller's station address which is in the form of
      08-00-2B-nn-nn-nn.  This can cause a problem with Pathworks
      clients who are not listening to the multicasted LAT service
      announcement messages.  They are expecting to utilize the
      AA-00-04-00-nn-nn address form.

   o  LAT messages may not be exchanged between two FDDI rings
      that are connected by an Ethernet.  This behavior may exhibit
      itself by the LAT session being stopped due to the retransmit
      limit having been exceeded.

   o  A system may crash with an INVEXCEPTN bugcheck at or around
      LTDRIVER + 250D in a SMP environment.

   o  When using a dedicated port with application LAT services, the
      LATCP  SHOW  SERVICE  command  can  incorrectly list dedicated
      ports for the wrong application services.

   o  When a user performs a SET HOST /LAT to an Infoserver or another
      system that requires a password for the LAT service, the message

         %LAT-I-DISCONNECTED, session disconnected from SERVICE
         -LAT-I-END, control returned to node NODE_NAME

      is returned after the user provides the password.

   o  An OpenVMS VAX system has non-paged pool exhausted and most of
      the blocks in non-paged pool contain LAT service announcement
      messages.  Under certain circumstances, a VMScluster system
      could crash with a CLUEXIT type of bugcheck.

   o  When the system is attempting to transmit a LAT reject slot to a
      remote terminal server, it crashes because the virtual circuit
      for the connection has already been deleted.  This crash is
      mostly seen with systems that have many connections from an
      Emulex terminal server.

   o  The system crashes with INCONSTATE in LTDRIVER while attempting
      to transmit a LAT run message.


INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system must be 
rebooted.  If the system is a member of a VAXcluster, the entire cluster 
should be rebooted.
