HP Services Software Patches - x25alp_e02b011
 
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for ZWDRIVERS in X.25 for OpenVMS Alpha V1.1B 
on OpenVMS Alpha V7.0 through V7.1.  This kit addresses the 
following problems: 


Problems Addressed in X25ALP_E02B011:

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

  o  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.)                   
                                                                     
  o  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.
