Patch Name:  PHNE_1440

Patch Description: Newest update to the S700 tty subsystem for HP-UX 8.07.

    5003-070854:   When RTS/CTS flow control is enabled via the device file
                   minor number, it wasn't possible to identify the device
                   file after "ps -ef", "who", and/or "tty" was executed.
                   The device file ownership would not change to the user
                   login name. This patch corrects these problems.

    5003-034140 : Data loss occurred at 38K baud or greater when
                  RTS/CTS hardware flowcontrol was enabled.  This
                  previous implementation of RTS/CTS hardware
                  handshake protects the hardware (input FIFO) and
                  not the software (mux driver).  This patch was
                  developed to protect the software as well.  Thus,
                  preventing the loss of data at high baud rates.
                  (The S700 supports inbound data rates up to
                  230.4K baud with no data loss using h/w flowcontrol.)

    4701-086843 : Serial driver would occassionally lose inbound data,
                  one byte at a time, at baud rates of 38.4K and above
                  was fixed.

    5003-042887 : This fix prevents a system panic when 'stty cr2 nl1'
                  are executed.

    5000-668442 : This fix gave the user more flexibility in
                  configuring the series 700 serial port's response
                  to the XOFF character by selecting a particular
                  trigger level. The trigger level on the built-in
                  serial port is controlled through two bits in the
                  minor number of the device file.

    4701-088625 : Data transmission resumes on a flow controlled
                  port (XOFF'ed) when ioctl(TCSETA) call.

    4701-092569 : At high baud rates, the delimiter count is not
                  tracked correctly in the line discipline.  This
                  causes canonical reads to not be terminated by
                  the new line character.

    4701-092908 : Resolved a one to twelve bytes data loss problem
                  in 5 megabyte transfers.

---------------------------------------------------------------------------
After getting the patch onto your machine, unshar the patch (sh PHNE_1440).

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/PHNE_1440.updt"
   (this assumes that you are in the /tmp directory where PHNE_1440.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".
6) From here on follow the standard directions for update.

The customized script that update runs will move the original software
to /system/PHNE_1440/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended that
you move the PHNE_1440.text file to /system/PHNE_1440 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_1440.updt of=/dev/rmt/0m bs=2048
