first argument to the command must be the recognized name of a
function key from the list:

F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 
Home End PgUp PgDn CUP CUL CU5 CUR CUD

If only one argument is supplied, the mapping for the specified
key is displayed.  If more than one argument is supplied, the
keyboard mapping is changed.  Arguments 2-n are character code
specifiers in the format used to define a funckeymap entry.

WARNING: If found to be syntactically correct, a mapping change
is installed immediately.  If incorrect mapping of the HOME key
is requested, you may lose control of ECU.

Examples:

    fkmap f10       display F10 mapping
    fkmap Home ^Z   map Home to ^Z
                    after this command, type ^Z for Home

55.  Non-SCO color appears broken and it is beyond me to fix it.
If you want to diddle with it, look at the top of ecutty.c at the
list of conditionals regarding USE_COLOR.  I'd appreciate
patches.  BTW, in the past, I have attempted fixes for ISC
character attributes like underlining and standout, but I've
never heard back.  Are there attribute problems on ISC (3.2 or
other)?

56.  The procedure command exec was added:

usage: exec <string>

This function executes a string as a procedure statement.
Argument <string> must contain an ecu statement exactly as
might appear on a procedure line, with a few exceptions.

1. There may be no label: the first command may 
   start in column one.
2. You should not execute a goto, gosub or return.
3. You should not code if, while or compound statement
   brackets.

You are on your honor with regard to items 2 and 3 above.
If you stretch it, it will break.

Example:

    $s20 = 'Home';   $s30 = '^H' 
    $s21 = 'End';    $s31 = '^E'
    $s22 = 'F1';     $s32 = '^A'
    $s23 = 'F2';     $s33 = '^B'
    $i10 = 0
    whilei $i0 < 4
    {
        $s0 = 'fkmap '+$s[20+$i10]+' '+$s[30+$i10]
        exec $s0
        $i10 = $i10 + 1
    }

57.  ECU has been made successfully with gcc 2.2.2.  There is a
bug in the configure procedure in the 2.2.2 I received.  In
attempting to configure for 3.2v4, the tm.h header file got
linked to the wrong file.  Make sure tm.h is linked to
config/i386_sco4.h and not config/i386_sco.h.  Starting with
2.2.2, those nice M_ identifiers are predefined by gcc.  I wish
everybody's compiler had a predefine that would identify the
environment.

The Configure procedure is unchanged.  Answer yes to the question
about version 1.40 or later.

58.  John Dashner, wa4cyb!jmd, proofread the main manual (THANKS).  His
changes are in the manual.

FINAL 3.20 notes 59-65

59. Expect/respond \M and \m implimented for SVR4.  The old \m
millisecond delay is now ~n[##].  See the procedure manual in the
description of the expresp command.

60. Further bugs with managing line chown/chmod fixed.
A directly specified line not managed by getty was not getting
chowned back to uucp when the line was closed.

61. Better syntax checking is done when reading Devices lines.

62.  A bug in ecusz caused data transfer rate calculations to be
wrong after any receiver ZRPOS ("nak") after the first one at
transfer startup.

63.  A "Resume interrupted transfer" choice has been added
to the interactive sz menu.  An equivalent -r switch was added
to the sz procedure command.  Previously, you had to "just know"
you can sneak switches to the file transfer protocols by
prefixing them to the file list.

There is still no clean way for the sz procedure command to set
the ZMODEM window size on sends other than the aforementioned
trick.  The thing to do here is

    sz '-w 65536 file1 file2'

There is no foreseeable reason this hack will cease to work.
However, if I get 1.0001 requests, and I'll come up with something
better.

64.  The receiver process was being started too soon after a
connect resulting for a directory entry dial.  As a result,
if ther remote began transmitting very soon after connect
or if there was remaining modem dialog remaining bufferred
in the tty driver, the CONNECT or [interactive mode] messsages
could have been intermixed with data from the line.
This longstanding nuisance bug has finally been fixed.

65.  The rtscts procedure command would take only on/off/yes/no
alphabetic arguments.  Now it will accept numeric arguments
like its interactive equivalent.
