X
X
X    6.77  sy
X
X
X    usage: sy [-a[l]] [<label-str>] <filelist-str>
X
X    This command invokes the YMODEM Batch (not to be confused with XMODEM-
X    1K)    file transfer protocol to send one or more files.
X
X    If switch '-a' is supplied,    newlines are converted to carriage
X    return/linefeed pairs.  If '-a' is omitted,    the file(s) are    transmitted
X    without modification.  If '-l' is supplied,    then <label-str> specifies a
X    string to display on the bottom of the file    transfer screen.  If '-l' is
X    omitted, then <label_str> must also    be omitted.
X
X    Integer variable $i0 receives the exit status from the transfer. If    0,
X    transfer was normal.  Note:    procedure execution IS terminated by a
X    SIGINT to the spawned file transfer    process.  This is different than for
X    versions prior to 3.10.  If    $i0 is set to -1, the file transfer program
X    did    not begin.
X
X
X    6.78  system
X
X
X    usage: system [-ls]    <cmdstr>
X
X    <cmdstr> is    passed to the Bourne shell.
X
X    If switch '-l', is supplied, the attached communications line becomes
X    the    stdin and stdout for the command.
X
X    If switch '-s', is supplied, all ECU file descriptors remain open.    The
X    -s option is important to include if you pass the ECU line file
X    descriptor to another process.
X
X    Integer variable $i0 is set    to the spawned process'    exit status if the
X    process exits "normally", or 0x100 if the process is killed, dumps core
X    or interrupted.
X
X    Note:  procedure execution is NOT terminated by a SIGINT to    the spawned
X    process.  It is the    responsibility of the procedure    to process the exit
X    status returned in $i0.  If    $i0 is set to -1, the file transfer program
X    did    not begin.

X
X    6.79  sz
X
X
X    usage: sz [-anf[l]r] [<label-str>] <filelist-str>
X
X    This command sends files using ZMODEM/CRC-32.  The remote protocol must
X    have been started prior to the execution of    this command unless the
X    remote has automatic ZMODEM    frame detection.
X
X    Switch '-a'    specifies an ASCII transfer; the default is binary.
X
X    Switch '-f'     causes    the full pathname of each file to be sent;
X    otherwise, the simple filename is transmitted.
X
X    Switch '-l'    with the <label-str> argument specifies    a string to display
X    on the bottom of the file transfer screen.    If '-l'    is omitted, then
X    <label_str>    must also be omitted.
X
X    Switch '-n'    causes the receiver to accept files with do not    already
X    exist at the remote    system or which    have older times of  last access
X    that at the    sending    system.     Not all remote    protocol software will
X    accept or obey this    option.
X
X    Switch '-r'    causes an interrupted file transfer to be resumed.  if the
X    remote receiver supports the ZMODEM    protocol feature.
X
X    Integer variable $i0 receives the exit status from the transfer. If    0,
X    transfer was normal.  Other    $i0 values possible:
X
X      1-126:   count of    files not transmitted (see ~/.ecu/log)
X      127:     127 or more files not transmitted (see ~/.ecu/log)
X
X    Other ecusz    error codes are    shown here for refernce, but they are
X    converted by ECU to    printed    messages and result in procedure
X    termination.
X
X      128-192: process terminated with signal==code-128

X    6.80  vidcolor
X
X
X    usage: vidcolor <type> <fcolor> [<bcolor>]
X
X    This command allows    control    over the internal color    choices    ECU makes.
X    <type> must    be one of the following:
X
X
X     normal      - normal video color
X     reverse  - reverse video color
X     notify      - color used for low key notifications such as
X            "[interactive mode]" and "[procedure finished]"
X     success  - color used for modem CONNECT messages and other
X            "success" notifications
X     alert      - color used to alert    user for warning or caution
X            purposes
X     error      - color used to display error    status or messages
X
X
X    <fcolor> and <bcolor> are color names as described in the description of
X    the    color command. <fcolor>    choses the foreground color and    must be
X    supplied.  <bcolor>    choses the background color and    is optional; if    not
X    supplied, the background color is black.
X
X    Note: The vidcolor normal and reverse options are analogs of the color
X    and    color -r command.
X
X
X    Examples:  (showing    ECU default internal color list)
X
X    vidcolor normal    lt_green
X    vidcolor reverse red white
X    vidcolor notify    gray
X    vidcolor success lt_green

X           any kind    or number of statements
X           (labels are not allowed inside braces)
X       }
X
X
X    This command executes a loop one or    more statements    based on a test    of
X    two    integer    quantities.  The <rel-op> argument is descibed in a earlier
X    subsection titled "Relational Operators." See the description of the

X    7.    Special    Procedures
X
X
X    ECU    provides for special "hook" procedures to be executed at certain
X    times.  Their use is encouraged, but you must take precautions not to
X    excecute any unreasoable commands in them, for the are rather "raw"
X    hooks and it is easily possible to confuse ECU by performing illogical
X    operations in them.    Judicious use can, however, be quite productive.
X
X    They are searched for in the same manner as    any other procedure, so    you
X    can    have a customised version of them in a working directory and a
X    default in your ~/.ecu subdirectory.  No error is reported if they are
X    not    found.
X
X
X    7.1     _rc.ep
X
X
X    Afer ECU is    initialized, but before    it presents the    setup screen or
X    executes a -p initial procedure, procedure '_rc' is    executed with no
X    arguments.    (It is named in    the tradition of /etc/rc, .mailrc, etc..)
X    This procedure can be used to customize the    ecu environment    prior to
X    beginning the usual    operation.  This is not    a place    to do any dialing or
X    long-lived operations, nor is it possible to bypass    the setup screen:
X    for    this, use the -p initial procedure.
X
X    The    %getenv() function may be useful in here (Am I running on an xterm?
X    Do I want to change    the prompt string from the default environment
X    variable $ECUPROMPT?).
X
X    Procedure commands likely to be of interest    here:
X
X       autorz
X     * baud
X       color
X       dcdwatch
X     * duplex
X       prompt
X       rtscts
X     * setline
X
X
X    Commands marked with an asterisk affect the    initial    (default) values
X    presented on the setup screen.
X
X    If _rc.ep returns a    non-zero status    or fails (due to syntax    or other
X    error), ecu    terminates immediately.

X
X    7.2     _connect.ep
X
X
X    This procedure is executed after every connection success after the
X    CONNECT message ("result code") is printed.     It is passed one argument,
X    the    "result    code" string generated by the dialer function (e.g.,
X    "CONNECT 19200").
X
X    You    may use    %rname and other functions and features    to customize this
X    function based on the particular system just reached.  Note    that integer
X    variable $i0 and string variable $s0 set zero prior    to executing the
X    function.  This function may modify    the behavior of    coorperating dialer
X    functions by setting the value of numbered string or integer variables.
X    In particular, the dialer function will inherit the    values of $i0 and
X    $s0    when this special function terminates.    Be careful of what you do in
X    here since MANY ecu    procedure commands affect $i0 and $s0 as a side
X    effect of their operation.    Even if    you know what you do in    _connect.ep
X    does not modify $i0    or $s0,    use of the preservation    technique shown    in
X    the    example    below may save you headaches if    you add    to the function    in
X    the    future (long after you have forgotten this pedantic admonition).
X
X    If this procedure fails (abnormal procedure    termination or non-zero
X    return code), ECU hangs up on the line and proceeds    as if the connection
X    failed.

X    the    logical    system name (the dial directory    entry name or the phone
X    number) and    the "result code" string generated by the dialer function
X    (e.g., "BUSY").  The function is called after $i0 has been set to 1    and
X    $s0    has been set to    the result code.  This function    may modify the
X    behavior of    coorperating dialer functions by setting the value of
