Patch Name:  PHKL_1649

Patch Description: Absolute cursor positioning on ITE may return cleared text.

 Absolute cursor positioning operations on the ITE (via ESC&axxcyyR) may
 result in the return of text previously cleared from the display.

 Programs affected: Any text based application using the ITE as a display
                    device.

 File Fixed: /etc/conf/libhp-ux.a (specifically the ite_scroll.o module
             within this library)

 Symptoms:
 If absolute cursor addressing is used to place the cursor below the beginning
 of an area previously cleared, subsequent display operations into that
 previously cleared area may reveal old display data.

 This behavior can be demonstrated by the following script:

 #!/bin/sh
 echo "\033H\033J"       # Home and clear to end of display
 echo "\nI am here\n"    # display text on line two
 echo "\033H\033J\c"     # Home and clear to end of display
 echo "\0337a40c12R\c"   # place cursor at row 12 column 40
 echo "\033J\c"          # clear to end of buffer
 echo "\033H\c"          # home
 # at this point, when the cursor is moved across line 2, the
 # text "I am here" will reappear.

 Fix:
 The ITE scroll buffer will now be cleared correctly when absolute
 cursor addressing is used.

After getting the patch onto your machine, unshar the patch (sh PHKL_1649).

To install this patch do the following:
1) Run /etc/update (Note: you must be logged in as 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: /tmp/PHKL_1649.updt"
   (this assumes that you are in the /tmp directory where PHKL_1649.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".

The customized script that update runs will move the original software

order to recover from any potential problems.  It is also recommended that
you move the PHKL_1649.text file to /system/PHKL_1649 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=PHKL_1649.updt of=/dev/rmt/0m bs=2048
