Installation Instructions:  

    Please review all instructions and the Hewlett-Packard

    and conditions for precautions, scope of license,

    before installing this patch.


After getting the patch onto your machine, unshar the patch
(sh PHNE_4818)

NOTE: Before attempting to install this patch, check to verify
      that ocd or ocdebug are NOT running.

To install this patch do the following:
1) Run /etc/update (Note: you must be root to update a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return"
   or "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: PHNE_4818.updt" assuming
   you are in the directory where PHNE_4818.updt has been placed.  In some
   versions, you may need to enter the absolute path name.  In others, the
   default "/dev/rmt/0m" may not appear in the field as default.
5) Press "Done".
6) Move to the "Select All Filesets on Source Media" line and press "Return".

The customized script that update runs will move the original software
to /system/PHNE_4818/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended
that you move the PHNE_4818.text file to /system/PHNE_4818 to be
retained for future reference.

If you wish to put this patch on a magnetic tape and update from the
tape drive, dd a copy of the patch to the tape drive.  As an example
the following will create a copy of the patch that update can read:

    dd if=PHNE_4818.updt of=/dev/rmt/0m bs=2048

Special Instructions:

Add a line to the printer interface scripts:

  Add the line :

      stty exta <&1 2>/dev/null

  to the end of the interface script, just prior to the exit command.


  Example:

     <body of interface script>
     ....
     ....
     ...
     stty exta <&1 2>/dev/null

     exit
     <end of interface script>

  The interface scripts should be located in /usr/spool/lp/interface.
  Make this change for each printer configured with DDFA.
