       ECO Kit X25ALP_E02B011 Description


       Corrections have been included for the following 
       components:


           o  SYS$COMMON:[SYS$LDR]X25$ZWDRIVER.EXE

           o  SYS$COMMON:[SYS$LDR]X25$ZWDRIVER.STB



       Problem Description

       1) Stop ZWDRIVER needlessly consuming large amounts CPU time  on
       AlphaServer 4000 family systems.

       2) On PBXDP boards with more than 2 ports, correctly report  the 
       state of the modem control signals of ports above the first two. 
       (The previous driver incorrectly reported  the  state  of  modem 
       control signals for port 0 as the state  of  the  modem  control 
       signals for each of ports 0, 2, 4 and 6 AND reported  the  state 
       of the modem control signals for port 1  as  the  state  of  the 
       modem control signals for ports 1, 3, 5 and 7.)

       3) Ensure the state of the modem control  signal  DTR  always is 
       preserved across modifications to the  register  which  controls 
       DTR.   Previously  the  board  read  the   port   register   and 
       inadvertently changed bit settings when  doing  so.  The  change 
       corrects   this   situation   for   all   ports   on  the  PBXDP 
       synchronous communications card.



       Installation Overview

       Install this kit with the VMSINSTAL utility by logging into  the
       SYSTEM account, and typing the following at the DCL prompt:

         @SYS$UPDATE:VMSINSTAL X25ALP_E02B011 [location of the saveset]

       The  saveset  location may  be a tape drive, or a disk directory 
       that contains the kit saveset.

       This  system must be  rebooted for the new X25$ZWDRIVER image to
       be loaded.
