This is patch 4 to ECU 3.20.

To apply this patch, extract the shell archive below in the ECU
distribution directory, creating one new file (PATCH04).
Then patch by

    patch -p0 < PATCH04

Then, make depend, make, su root, make install.
Configure is not necessary for this patch.

==> Patch 4 (from CHANGES)

13. [e-mail] (Jeff Johnson) suggested a change
in the SVR4 LCK.. logic, stating that the use of <sys/sysmacros.h>
is deprecated.

14. On some systems, the video attributes were not reverted to
"normal" after some reverse video or underlined strings (e.g,
"[interactive mode]").

15. I removed the Metro Link pts support.  This was quite obsolete
since only very early Metro Link software used pts'.

16.  FAS 2.10 users are getting SIGUSR1 sent to the transmitter.
I suspect this is a bug in FAS evoked by the kill(getty,SIGUSR1)
performed by ecuungetty, but I am have no real clue.  This needs
resolving, but I have little time right now.  This patch adds
signal(SIGUSR1,SIG_IGN) to eliminate the problem.

17. Console xon/xoff support has been added.  EMACS users
lament the loss of ^S/^Q.  (I personally consider it evolution
in action :->).  A new inetractive and a new procedure
command have been added  Also, the status is reported by
the interactive stat command.

   conxon on  - honor xon/xoff locally
   conxon off - pass ^S/^U to remote

If you turn conxon off, there will be no local software flow control
so you probably need hardware flow control for proper operation.
Refer to the rtscts command descriptions for more information
(I pray you are using a tty driver that supports the kind
of hardware flow control your modem requires).

18.  The procedure file transfer commands did not get
rearranged to look for the file transfer programs in the
ecu library directory.

19. Chains of else statements may fail to operate properly
in certain arrangements.  The known failure was fixed.

X+
X+ 7.  Information on tty "Device busy" errors and color support
X+ have been added to README.Q-and-A.  Obsolete information was
X+ removed.
X+
X+ 8. The -l switch was added to the fkmap commands:
X+        fkmap -l <name>
X+ The -l form reads an entire funckeymap definition matching <name>
X+ from ~/.ecu/funckeymap (if not found there, in a file by the same
X+ name in the library directory).  This form behaves exactly
X+ in the same manner as the command line switch -F.
X+ Due to the drastic nature of this command, if it fails to
X+ execute properly, ECU terminates itself.  Note that
X+ improper use of this form of the command can still render
X+ ECU an albatross (with Home unrecognizable).
X+
X+ 9.  The original high-bit character space assignments for Alt-A
X+ through Alt-Z that I chose for ECU made good sense ...  to a
X+ parochial American.  Michael Traub <emory!btcs.bt.co.uk!traub>
X+ sets me straight, but mapkey/README was incorrect.  Each hex
X+ value was off by one.
X+
X+ 10.  If the console has parity enabled, the interactive stat
X+ command now reports <7-bit kbd>.  Knowing this can be important
X+ if you are using Alt-[A-Z].  Or if you are trying for some kind
X+ of unlikely tandem 8-bit transparent path (telnet to a box, run
X+ ecu to call home, login, use ECU there to talk to your amateur
X+ radio PK-232/MBX TNC over 14 MHz AMTOR to the UK to a Kantronics
X+ TNC hooked to an SCO box, login, make an ECU call to a certain
X+ Universal Import-Export ...  uh, hi -- I seem to have dozed off).
X+
X+ 11.  At least one ISC SVR3 user had a Devices entry with the
X+ modem control ",M" suffix I thought was only used in SVR4 UUCP.
X+ The suffix presence is now detected on all platforms.
X+
X+ 12. ecusea.c had two fcntl.h inclusions.  XENIX could not
X+ handle this.
X+
X+ ==> Patch 4
X+
X+ 13. [e-mail] (Jeff Johnson) suggested a change
X+ in the SVR4 LCK.. logic, stating that the use of <sys/sysmacros.h>
X+ is deprecated.
X+
X+ > Here is an excerpt from my <sys/sysmacros.h>:
X+ >
X+ >    WARNING: The device number macros defined here should not be
X+ >    used by device drivers or user software.  Device drivers
X+ >    should use the device functions defined in the DDI/DKI
