RBcomm is a lean and mean comm program which will run in 47K without
file transfer capability or 65K with file transfer capability. Since it
is so lean, you will not get a lot of the fancy features of other comm
programs, though there are plenty of features to let you get your work
done (I've been using it exclusively for over five years, and have
added features as I've found that I could be more productive with them
than without).

Features:
    small (runs in as little as 47K [65K with DSZ, 66K with Puma/MPt])
    DESQview-aware
    pop-up menus
    'type' a file to the remote system, optionally expanding blank lines
    seamless file transfer using DSZ, PCZ, or Puma/MPt
    Zmodem autodownload (others easily added)
    shell to DOS, using well under 1K while shelled
    keyboard reassignment, powerful keystroke macros, "DOORWAY" mode
    250-number dialing directory
    ANSI/VT102, VT52, and AVATAR level 0 terminal emulations
       [UnixWindows and AVATAR level 1 partially implemented]
    ANSI music
    132-column support
    supports the 16550A UART's FIFOs and speeds to 115,200 bps
       (a 4.77MHz 8088 can handle 19200)
    scrollback buffer

Registration:
    Continued use of DSZ requires registration with Omen Technology, Inc.
    See the DSZ documentation for details.

    Continued use of Puma/MPt requires registration with Matthew Thomas.
    See the Puma or MPt documentation for details.

    If you like RBcomm, send me a picture postcard of some sight in your
    area.  If you don't like RBcomm, feel free to send me a postcard
    anyway, telling me what you don't like.     I just might change the
    thing you don't like in the next release.

Support:
    None (after all, I'm not getting any money for this).  I will try to
    fix bugs as time allows.  When reporting a suspected bug, please
    include as much detail as possible (such as a verbose log if it
    involves the terminal emulation).

         on configuration

-------------------------------------------------------------------------------
Installation
------------

Before you use RBcomm for the first time, you need to tell it where to find
its support files and how to talk to the modem.     To do so, copy the RBcomm
files to the directory in which you wish to install them, change to that
directory, and type

    RBCONFIG CONFIG COMM.COM

(if COMM.COM is not in the current directory, use the full path, i.e.
C:\COMM\COMM.COM, or RBCONFIG will not be able to find it)

Please do not use your original copy.  If you forget to run RBCONFIG, you
will be told to do so when you attempt to run COMM.COM.

You will now be asked (via a menu) to fill in several groups of information.
Note that you may use either forward slashes ('/') or backward slashes
('\') to separate directories in a pathname.

Press 'D' to set the directories and extensions to use.
   RBcomm dir:    where the keyboard macro files and dialing directory are stored
   Swap directory: where to store the swap file when running DSZ or COMMAND.COM
        and neither EMS nor XMS is available.  A RAMdisk is ideal for
        storing the swap file, which will be about 64K (the exact size
        depends on your setup).
   Use XMS if available:  if set to N, RBcomm will always swap to disk in the
        directory specified by the previous item, or EMS if enabled.
        If set to Y (default), RBcomm will swap to XMS memory if there
        is enough available.
   Use EMS if available:  if set to N, RBcomm will always swap to either XMS
        (if available) or to disk.  If set to Y (default), RBcomm will
        swap to EMS memory if XMS is unavailable and there is enough
        free EMS.
   Macro file extension:  default extension to apply to keyboard macro files
   Default macro file:      keyboard macro file to load on startup and hangup
        if this file does not exist, RBcomm will use a built-in set
        of default key bindings

Press 'S' to select the serial port to use.  You may setup
configurations for "COM1" through "COM4", as well as the default port to
use when not otherwise indicated in the dialing directory. The values
given for "COM3" and "COM4" need not bear any relationship to the
numbering of the actual serial ports in your system (you could, for
example, set them up to be the same as "COM1" except for the length of
the break signal).  RBCOMM does check that "COM1" and "COM2" exist
according to the BIOS data area, however, to avoid running in a DESQview
window which has incorrect settings for supporting serial
communications.     Break length specifies the length of the signal that is
sent when you give the break command (default Alt-B) in multiples of the
standard clock tick of 55ms.  You may specify a separate setup string
for each port.    The setup string needs to ensure that the modem echos
back any commands it is sent, and asserts carrier detect only while
actually connected with another modem (for Hayes-compatible "AT" command
sets, "E1&C1").

Press 'M' to define the modem setup.  In this section, you need to enter
several strings to be sent to the modem, and the strings the modem will
return to RBcomm.  Note that you may enter control characters such as ^M
(carriage return) by pressing control-Q followed immediately by the
desired control character.  You can enter a DEL (ASCII 127) by pressing
Alt-D.    Since most modems nowadays use the Hayes 'AT' command set, the
only entry you are likely to change is "dial prefix", which will be
"ATDT" for touch-tone dialing or "ATDP" for pulse dialing.  Note that
the responses should be set to the shortest substring that uniquely
identifies the response.

Press 'P' to setup dialing parameters.    You may specify the name of the
dialing directory, how long to try before declaring a time-out, and how long
to wait before trying again.

Press 'F' to set the commands and parameters to execute for the various
file transfer protocols.  You may embed replaceable parameters
introduced by a percent sign into the command strings--see the EXEC
macro command for details.  An additional replacement of %F is available
which expands to the name(s) of the file(s) to transfer.  Note that the
default "portx" will cause DSZ to report the port as COM9, but it will
still use the correct serial port. You need to use "portx" if you will
be using more than one serial port.

Press 'C' to set the colors you want RBcomm to use.  You may select the
default and "underlined" colors, as well as the colors to use on menus
and in the scrollback viewer.

Press 'V' to determine whether 132-column mode should be enabled, whether
to start in 132- or 80-column mode, and the register values needed to set
132-column mode.  When running under DESQview, RBcomm can tell DESQview to
set the virtual screen size to 132 columns if you specify zero for AX.
DESQview will then display as much as it can at one time; this is useful
if you need a 132-column display but do not have a video board which
supports 132 columns.

Press 'T' to adjust a number of toggles.  Many of these may also be changed
from within RBcomm.
   "Local echo" allows you to turn on half-duplex operation by default.
   "Verbose" sets whether to include terminal control sequences in a log file.
   "Strip parity bit" specifies whether the high bit should be stripped from
      all incoming characters, even when parity is set to None.
   "Visual bell" specifies whether to flash the screen instead of sounding a
      beep when a ^G is received (internally-generated beeps always use sound).
   "Should backspace send delete" specifies whether the values sent by
      backspace and control-backspace should be exchanged.
   "Check for enhanced keyboard" determines whether RBcomm will use the
      enhanced keyboard BIOS calls if it thinks those calls exist.  Some
      systems incorrectly indicate support for those calls.  Set this to
      'N' if RBcomm appears to hang your system.
   "May RBcomm to change NumLock" determines whether RBcomm will change the
      state of the NumLock key when it receives the "keypad numeric mode" or
      "keypad application mode" commands.  Disabling the NumLock changes is
      useful for laptop users without a separate number pad.
   "Save screen" specifies whether the current screen is saved prior to
      executing external programs (except for file transfers) and restored
      afterwards.  If the screen is saved, you will be asked to press a
      key before the screen is restored.

Finally, press 'O' for miscellaneous options.
   "Heap size" determines how much memory RBcomm allocates for macro files,
      macro execution, and some of RBcomm's own processing.  This must be
      set to at least 800 bytes more than the size of the largest macro
      (.RBM) file.  A larger setting will not harm, but will needlessly
      use more memory.    Should you get an "out of memory" or "stack full"
      error message, you will need to increase this value.  When set to
      zero, RBcomm will grab as much heap space as it can (about 24K).
   "Receive buffer size" determines how much memory RBcomm allocates
      for storing characters received from the serial port which it has
      not yet been able to process.  The default of 2048 is sufficient
      for most uses; a larger buffer may provide somewhat better
      performance at very high speeds on a slow machine, while a smaller
      buffer saves some memory.
   "Number of screens" specifies how many virtual terminals to allocate
      space for.  This will become useful for the UnixWindows protocol;
      most users will want to set this value to 1.  Keeping multiple
      screens allows you to remember one or more screens of data and
      return to them at a later time.
   "Time between sends in idle mode" determines how often Idle mode (see
      Alt-I) sends some characters to keep the connection alive when you
      are not actively using RBcomm.
   "String idle mode sends" specifies what characters to send to keep the
      connection alive.
   "Answerback message" allows you to specify the string which RBcomm will
      send when it receives a ^E.  The ANSWERBACK macro command can override
      this setting.
   "Default pace character" determines which character RBcomm will wait for
      after sending each line of text from the file being typed to the
      remote system.  Setting this value to ^@ means that RBcomm will not
      pause after each line.  This setting may be changed while RBcomm is
      running by using the PACECHAR macro command.
   "Use EMS for scrollback" determines whether RBcomm will allocate 32K
      of expanded memory (if available) for the pager and scrollback
      buffers.    If set to Y and at least 32K of EMS is available, RBcomm
      will give you a 6K pager buffer and 26K scrollback buffer regardless
      of the next two settings.
   "Size of non-EMS pager buffer" determines how much memory RBcomm will
      allocate for the file pager's buffer when EMS is not available or
      has been disabled.  Larger values can improve the pager's performance
      on files with long lines, but values greater than 6-8K will not have
      much of an effect unless you have an extremely large screen.  Values
      smaller than the number of characters on the screen will cause
      significant slowdowns when viewing files or displaying a directory,
      due to thrashing as RBcomm constantly re-reads data.
   "Size of non-EMS scrollback buffer" determines how much memory RBcomm
      will set aside for storing text received from the serial port.  As
      new text comes in, the oldest will be discarded.    Whatever text is
      in the scrollback buffer may be viewed with Alt-O.

On choosing "Quit" from the menu, you will be asked whether to save the
new configuration to disk.  If you specify that you want to save the changes,
the executable on disk will be updated.

---------------------
DESQview Installation
---------------------

After performing the file copy and configuration described in the
previous section, you need to install RBcomm on the DESQview Open
Window menu.  In DESQview, tap the Alt key to bring up the DESQview
menu, then press "O" for the Open Window menu, and "AP" to add a
program.  Select "Other", then fill in the directory in which you've
placed the RBcomm files and press Enter.  You will be given the choice
of RBcomm, RBcomm plus DSZ, and RBcomm 132col; select one or more and
press Enter.  Now use "CP" from the Open Window menu to change the
paths and/or the keys for starting RBcomm.

The only difference between "RBcomm" and "RBcomm + DSZ" is that the
former allocates the minimum amount of memory for RBcomm to run (46K),
which is not enough to invoke DSZ, but does save 19K when you do not
need file transfer capability.  Should RBcomm complain about
insufficient memory (the window exits almost instantly), decrease the
heap size on the "Other options" menu in RBCONFIG.  If your environment
is particularly large, you may need to use Change a Program to increase
the window sizes by a K or two.  With certain screen sizes, you may
also need to give RBcomm 1K of system memory (on the advanced options
screen).

To get a 132-column display under DESQview, configure RBcomm to use
132-column mode and then make a .DVP file using "Change a Program"
which has all fields except for "maximum width" set to the desired
values.  Change a Program only allows 127 columns in the window, so
choose an arbitrary size smaller than that.  After pressing Enter to
save the .DVP, run the included DVPWIDTH program to change the maximum
width to 132 columns, i.e.
    DVPWIDTH 132 RZ-PIF.DVP
You must give the full name of the .DVP file, including the extension.
Note that Change a Program will force you to change the window's width
if you have set the width greater than 127 and run Change a Program
again.

If you do not wish to use the DVPWIDTH program, or your version of
DESQview experiences difficulties with a 132-column setting in the .DVP
file, RBcomm can still use 132-column windows through an alternate
method.  For this alternative, you must give it enough "system memory"
to store the entire maximum-size screen.  Whatever memory is used to
store the initial screen size set under "Window Position" is then
wasted, so that size should be set fairly small (such as 15 columns by
the desired number of rows).  If you are not interested in the reason,
skip the rest of this paragraph.  DV normally reuses the same section
of memory when resizing the virtual screen.  However, resizing it
beyond the maximum defined by the .DVP causes an entire new buffer to
be allocated.  Thus, minimizing the "maximum screen size" also
minimizes the DESQview overhead by reducing the size of the screen
buffer which gets discarded.

RBcomm is sufficiently DESQview-aware to ask DV for the size of the
screen. If you want a 120x60 screen, just set the maximum window size
to 120 columns and 60 rows.  DESQview will display as much as it can on
your screen, but RBcomm will use the full size.  If you have enabled
132-column mode with RBCONFIG, RBcomm will also switch to 132 columns
by the given number of rows when it receives the sequence "<Esc>[?3h".

RBcomm refuses to load itself twice on the same serial port when
running under DESQview.  However, when shelled to DOS, you can load
another copy in a different window, but make sure to exit the second
copy before returning from the DOS shell, or the first copy will abort.
The method RBcomm uses is compatible with ONLY1.SHP using the names
"COM1" through "COM8" (depending on the serial port), so you can also
keep RBcomm from conflicting with other programs that use a serial
port, such as BBS mailers.

Finally, RBcomm returns the rest of its time-slice to DV if it doesn't
need a full slice.  This improves the performance of programs in other
windows, and makes supplemental programs such as TAME unnecessary (as
phrased by TAME's author, RBcomm is "DV-polite").

-----------------------------------------------------------------------------
Dialing Directory
-----------------

The dialing directory is a specially formatted data file (rather than a
plain text file) containing up to 250 entries.  This data file may be
created and maintained with RBCONFIG (see Editing the Dialing Directory
below).

For the convenience of those using RBcomm version 3.31 or earlier, or
those wishing to distribute dialing entries for other RBcomm users,
RBCONFIG has the capability to compile a plain text file into an RBcomm
dialing directory.  In the plain text file, each dialing entry consists
of two lines, looking like this, with no blank lines between entries:

    Doctor's WOC Inn
    14126214604|4800N81|B|OPUS|password|\\N2

The first line contains the description which will be used on the dialing
directory screen and when dialing.  The second line contains six fields
separated by vertical bars.  These fields are

     1. number to dial (direct connection if empty)
     2. modem parameters, containing in order
      baud rate (110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400,
             57600, 115k)
      parity    (N for none, E for even, O for odd, S for space,
             M for mark)
      data bits (5, 6, 7 or 8)
      stop bits (1 or 2)
      handshake to use when receive buffer is full
            (H for hardware RTS/CTS, X for software XON/XOFF)
            (optional, default is hardware)
      timed call flag
            (if handshake present and the character after the handshake
             is T, a short "bip" will sound about 50 seconds into each
             minute after establishing a connection.  Every five
             minutes, the "bip" sounds twice)
      serial port number
            (if handshake is present, following either the handshake
             character or the "T" timed call flag with a comma and
             the number of the serial port will tell RBcomm to switch
             to that port before dialing)
     3. terminal emulation
      A for ANSI with VT102 extensions
      B for ANSI-BBS (same as ANSI, but clearing screen also homes cursor,
              and character set switching is disabled)
      V for VT52 with H19 extensions
     4. keyboard macro file to load
     5. password for this system (used by PASSWORD macro command).  Display of
      passwords in the dialing directory may be turned on or off with
      RBCONFIG.
     6. optional modem setup string, minus command lead-in defined by RBCONFIG
      (may include vertical bars).    In the example above, the \\N2 tells
      my modem to use MNP error correction.

If the keyboard macro file field is non-empty, the specified file will
be loaded immediately upon successfully connecting with the remote
system.  Since each entry in the dialing directory can specify an
independent set of keyboard macros, you can have a different set of
keyboard bindings for each system. If the macro file specifies a
binding for the ONLOAD "key", that macro will be executed immediately.
Further, if the macro file specifies a binding for the AUTO "key", that
macro will be executed immediately after the ONLOAD macro (if any).

The setup string may contain the following special sequences:
    ~    pause for half a second
    \n   send a line feed
    \r   send a carriage return
    \f   send a form feed
    \t   send a horizontal tab
    \a   send a ^G
    \b   send a backspace
    \!   send a break
    \~   send a tilde
    \\   send a backslash

Example modem parameters:
    1200E71X     default COM port, 1200 bps, even parity, seven data
             bits, one stop bit, use Xon/Xoff handshake when
             receive buffer fills up
    19200N81HT,2     COM2, 19,200 bps, no parity, eight data bits, one
             stop bit, use hardware handshake, and sound off
             every minute

Compiling the Dialing Directory
-------------------------------

Once you have created a plain-text dialing file, you must compile it
into the binary form used by COMM.COM.  The directory compiler is
invoked with
    RBCONFIG DIAL [-C<port>] <filename>
where <filename> is the name of the dialing directory to compile and
<port> is a number from 1 to 4 specifying which serial port is the
default port when none is explicitly given in the file.  Any extension
given with the filename is ignored; the text file always has the
extension .DIR and the compiled binary file has the extension .RBD.

If you want to add entries from a dialing file to the dialing directory
rather than creating a dialing directory from scratch, you can append
new entries to an existing directory with
    RBCONFIG DIAL [-A<port>] <dialdir> <filename>

Editing the Dialing Directory
-----------------------------

To interactively edit a dialing directory, use
    RBCONFIG DIAL [-E] <dialdir>

You may wish to read the section on the format of a plain-text dialing
file for information on the various options, and the special characters
you may use in the initialization string.


-----------------------------------------------------------------------------
Environment Variables
---------------------

RBcomm uses the following variables in its environment:

COMSPEC      specifies which program to load for Shell-to-DOS (Alt-D) and
      Execute-Program (Alt-G).

RBCOMM      specifies default commandline options (which may be overridden by
      the commandline).  See below for the valid options.  Note that only
      the first 160 bytes will be used due to internal space limitations.

SWAPDIR      overrides the default swap directory, where RBcomm stores itself
      when swapping to disk.

-----------------------------------------------------------------------------
Commandline Options
-------------------

RBcomm may be invoked with one or more options, described below.  These
options are processed from left to right; if an option is present
multiple times, the rightmost instance will be the one in effect.  The
options in the RBCOMM environment variable (if present) are processed
before the commandline, and thus are overridden by the commandline.
Options are not case-sensitive.

    -B    use BIOS calls to display characters received from the
        serial port (aka 'port check writes').  RBcomm's own
        menus and messages will still use direct screen writes.
        This option is primarily for the convenience of people
        using screen readers.

    -Cn    select COMn, where 'n' may be 1 to 4.  This option
        overrides the default set with RBCONFIG.

    -Ddir    set the RBcomm directory to 'dir'.  This option overrides
        the RBCONFIG default.

    -Mfile    set the default macro file to use whenever not connected
        to a remote system.  This option overrides the RBCONFIG
        default.  Only the first 8 characters are used.

    -Nfile    set the RBcomm dialing directory to 'file'.  This option
        overrides the RBCONFIG default; it replaces the RBCDIAL
        environment variable used by prior releases.  Only the
        first 12 characters are used; if no extension is given,
        it defaults to .RBD.

    -Pparm    force default parameters for the current serial port.
        Instead    of reading the port's parameters, RBcomm will
        set them to the value specified here.  'parm' is in the
        same format as used in the dialing directory, except
        that the port number is not allowed.  You may intersperse
        -C and -P options to set forced parameters for more than
        one port.

    numlst    a list of numbers to dial as if typed at the dialing
        directory (see Alt-Q below) prompt.  Each number must
        be separated from the next by a comma.  No blanks are
        allowed, as they signal the end of an argument on the
        command line.

-----------------------------------------------------------------------------
Memory Requirements
-------------------

RBcomm's memory usage is approximately

     38.1K + heap size + receive buffer + screens + pager buffer
       + scrollback buffer

where
     screens = number_of_screens * (max_size + 352)
     max_size = greater of (2*rows*columns) for 80 and 132-column modes
     pager buffer and scrollback buffer are both 0 if allocated in EMS

If there is insufficient memory, the scrollback buffer is shrunk; if there
is still not enough memory, the pager buffer is shrunk as well; as a
last resort, the number of screens is reduced.

-----------------------------------------------------------------------------
Keyboard Commands
-----------------

The commands described here may be bound to other keys, but the default
keystroke named here may always be used when preceded by Alt-= (hold down
the Alt key and press the equal sign at the upper right of the typewriter
section of the keyboard).

Alt-A    attack dial

    Repeatedly dials the number you select from the dialing directory
    until a connection is established.  You may also manually enter a
    number to attack-dial.

Alt-B    send break

Alt-C    call a number

    Dial the number you select from the dialing directory (once only).
    You may also manually enter a number to dial.  If you are currently
    connected to another system, you will be prompted whether to hang
    up.  Press Esc to abort the dial and return to the current session.
    Press "Y" to disconnect and then dial a new number, or "N" to maintain
    the current connection and load new macros and parameters without
    dialing.

    Note that the modem parameters always have an "H" appended when neither
    "H" nor "X" is present in the dialing directory, since the handshake
    defaults to hardware.

    See also Alt-Q.

Alt-D    DOS shell

    Temporarily exit to DOS.  Type "EXIT" to return to comm session.
    RBcomm will swap itself out of memory, leaving only 448 bytes plus
    its copy of the environment in memory (464 bytes when swapping to
    EMS).  When swapping to disk, a 46K-96K swap file will be created
    in the directory you specified with RBCONFIG, and will be deleted
    when you return to the comm session.  File transfers also create
    the temporary swap file.

Alt-E    toggle local echo

    By default, RBcomm assumes that the remote system will echo any
    characters you need to see.  After pressing Alt-E once, RBcomm will
    display any characters you type without requiring the remote system
    to echo them.  After pressing Alt-E a second time, RBcomm will once
    again assume that the remote system will echo characters.

    Note: you may also toggle local echo by pressing 'L' on the Alt-P
    parameters menu.

Alt-F    list files

    Display a three-up listing of the files matching a given filespec.
    This command uses the pager, whose commands are    listed in a separate
    section below.    Note that while the pager can back up past the
    beginning of its buffer, doing so can be slow for large directories.
    Please be patient if the screen is not updated instantly while backing
    up.

Alt-G    Go execute a program

    You will be prompted to enter a command.  Everything up to the first
    blank is the program to execute, and the rest of the line is the
    command tail to pass to the program.  If you do not specify an explicit
    path, RBcomm will search your PATH for you; similarly, if you do not
    give an explicit extension, RBcomm will look for both .COM and .EXE
    files.

    (to execute a batch file or a COMMAND.COM internal command, you should
    use
         "%VCOMSPEC% /c cmd"
    as the implicit COMMAND.COM invocation from earlier releases has been
    removed)

Alt-H    hang up

    Terminate the connection.  First drops DTR, and if Carrier Detect is
    still active, sends the modem's hangup string.    The default macro set
    is reloaded from disk (if present) or from the built-in defaults.
    If the CLEANUP "key" has a macro binding, it is executed before
    hanging up; if it includes the LOWER_DTR command, DTR will remain
    dropped.

Alt-I    idle

    This command allows you to keep a connection alive if you need to step
    away from your computer for a while.  Sends a space followed by a
    backspace every two minutes (configurable with RBCONFIG) until you
    press a key to cancel the command.

Alt-J    jump to directory

    Pops up a window displaying the current directory.  You may switch to
    a different directory by entering it in place of the displayed
    directory.  Relative paths without a leading slash or backslash will
    change to a subdirectory of the current directory.  If you specify a
    drive letter, that drive will become the current drive as well.

Alt-K    unused

Alt-L    toggle logging to file

    When pressed the first time, you will be asked for the name of a file
    to which all characters received from the remote system will be
    appended (percent signs introduce variable expansions--see the EXEC
    and OPEN_LOG commands below).  When pressed the second time, RBcomm
    will no longer append received characters to that file.     If verbose
    (see Alt-Y) is active, all characters will be appended exactly as
    received, otherwise any command sequences embedded in the received
    data are stripped out.

Alt-M    learn macro string

    When you press Alt-M, you will be asked to enter a text string of up
    to 79 characters, using the same editing keys used elsewhere.  This
    text string may be replayed with Alt-N.

Alt-N    play back macro string

    Plays back the last string recorded with Alt-M, sending it to the
    remote system.

Alt-O    scrOllback

    This command pops up the scrollback pager, allowing you to review
    text which has already scrolled off the screen.     The keystrokes
    which the pager understands are listed in a separate section below.
    In addition, 'M' marks the top of the currently displayed screenfull
    as the beginning of the region to write when 'W' is pressed.  After
    pressing 'W', you will be prompted for a filename.  The section of
    the scrollback buffer between the marked top (default: beginning of
    buffer) and the bottom of the currently displayed screen is appended
    to the specified file.

Alt-P    set parameters

    This command pops up a menu which allows you to set the following
    parameters:  COM port, speed, parity, parity stripping, handshake,
    backspace translation, visual bell, and terminal emulation.  You may
    also reset the terminal emulation to its initial state, in case the
    remote system leaves you stranded in a strange condition.  Press Esc,
    Enter, or 'R' to exit this menu.

    Note that Alt-P will discard any characters which have been received
    but not yet processed, because it always reinitializes the serial
    port when it pops down.

Alt-Q    dial queue of numbers

    Repeatedly dials each number you specify until a connection is
    established with one of the numbers.  The numbers are dialed in
    round-robin fashion until a connection is established.    A beep will
    sound to notify you of the connection, and the name of the remote
    system and the modem's connect response will be displayed.

    If there were multiple numbers in the previous dialing attempt,
    Alt-Q will immediately continue dialing the numbers which to which
    RBcomm has not yet successfully connected.

    You specify the entries to dial by giving the numbers as they appear
    in the dialing directory, separated by commas or blanks.  A number
    may be specified more than once, and will be dialed more than once
    during a round of dialing attempts.  As a shortcut, you may separate
    two numbers by a dash to dial all numbers in the range, inclusive.

Alt-R    receive file

    Pops up a menu allowing you to select the protocol with which you wish
    to receive a file from a remote system.     Press ESCape if you do not
    wish to receive a file.     Note that Zmodem features automatic download,
    so you do not need to press Alt-R unless you wish to give DSZ
    additional parameters.    You may also add additional autodownloading
    protocols--see the WHEN macro command in the next section.

    Not listed on the menu:     ^G, ^Y, and ^Z pop up a parameter prompt,
    then proceed with the download specified by the corresponding
    non-control letter.

Alt-S    send file

    Pops up a menu allowing you to select the protocol with which you wish
    to send a file to a remote system.  Press ESCape if you do not wish to
    send a file.  After selecting a protocol, you will be asked to enter
    the name of the file to send (Ymodem, Ymodem-G, and Zmodem allow
    wildcards and multiple filespecs).

    If you press the control character corresponding to the desired
    protocol, the file(s) will be deleted after a successful transfer.
    For batch transfers, only the files corresponding to the first
    filespec are deleted.

Alt-T    type ASCII file to other system

    sends an ASCII file to the remote system, pausing after each line
    for the return to be echoed.  The send may be aborted at any time
    by pressing Escape.  The EXPAND_BLANK macro command may be used
    to turn on blank-line expansion (send a single space instead of
    blank lines).  This feature is off by default.

Alt-U    load/save user interface as defined in keyboard macro file

    Note that keyboard macro files are always stored in the RBcomm
    directory as defined by RBCONFIG.

    WORDSTAR.RBM and EMACS.RBM contain the keyboard definitions for using
    WordStar (tm) and Emacs cursor movement commands on the cursor pad
    (i.e. Home goes to the start of the line, etc.)     EMACS.RBM also binds
    all Alt-letter keys to be Esc-letter, making the Alt key into a true
    Emacs meta-key.     You will need to use the Alt-= override to use the
    RBcomm commands while EMACS.RBM is loaded.

Alt-V    View file
    (toggle verbose, which used to be on Alt-V, is now on Alt-Y)

    Page through a text file.  This uses a simple file lister which
    only understands a few keystrokes; they are listed in a separate
    section below.

Alt-W    select Which screen is visible

    Displays a menu of the available screens.  Press the indicated
    number to make that screen the visible screen.    If UnixWindows
    is not enabled, the selected screen will also be made the
    active screen (characters received from the serial port are
    displayed on the active screen).  Under UnixWindows, the
    visible and active screens may be different, as the active
    screen is set by commands from the remote system; thus, only
    the visible screen is set by this command.

Alt-X    exit

    Terminate RBcomm.  If you are still connected to the remote system
    (Carrier Detect asserted), you will be asked whether or not to hang
    up.

Alt-Y    toggle verbose
    (previously Alt-V)

    Toggles the verbose mode used with Alt-L.  When not logging, the
    control characters which are not used for terminal commands will be
    displayed as ^X when received from the remote system.  When logging to
    a file, terminal command sequences will only be stored in the log file
    if verbose mode is ON.

Alt-Z    send file with Zmodem

    This command will send the specified file(s) using the Zmodem
    protocol.

Alt-1,2,3,4,5,6,7,8,9,0     dial first ten numbers in dialing directory

Alt-F1 through Alt-F10     dial 11th through 20th number in dialing directory

F1    pop up help screen

    Displays the contents of the help file for the current macro file
    (if that file is not found, RBcomm attempts to use RBCOMM.HLP).
    Press an Alt or function key to execute the default binding for the
    key.  Escape exits immediately, and any other key pages through the
    help file (if more than 20 lines long).

Alt--    cancel any pending WHEN, DELAYED, EVERY, or WINDOW commands

Alt-=    use default binding of next keystroke

    If the keyboard has been redefined, pressing Alt-= will allow you to
    access the built-in default definitions (as listed in this section).
    Press Alt-= and then immediately press the key whose default
    definition you want to use.  As a result, Alt-= is the only keystroke
    which may not be redefined.

-----------------------------------------------------------------------------
Line Editor
-----------

Whenever you are prompted for a line of input, you may use the following
keys to edit the line:

    Esc    abort
    Return    finish input
    Home    move to start of line
    ^A    move to start of line
    End    move to end of line
    Right    move a character right
    ^D    move a character right
    Left    move a character left
    ^S    move a character left
    ^Right    move word right (to next blank)
    ^Left    move word left (to previous blank)
    Del    delete the character under the cursor and shift remainder of
        line left
    Backsp    delete the character to the left of the cursor, and shift the
        remainder of the line left
    Alt-G    delete the word to the right of the cursor
    Alt-H    delete the word to the left of the cursor
    ^End    delete from the cursor to the end of the line
    ^T    transpose the two characters to the left of the cursor
    Alt-D    insert an ASCII DEL (127) character
    Alt-P    insert the contents of the cut buffer
    ^Q    treat the next keystroke as a literal character to insert

-----------------------------------------------------------------------------
Pager
-----

The pager is used to display directories, files, help screens, and the
scrollback buffer.  It is fairly simple, supporting the following
keystrokes:

    Up    move up one line
    Down    move down one line
    PgUp    move up one screenfull
    PgDn    move down one screenfull
    Space    move down one screenfull, exiting if already at end of
        file/directory/buffer.
    Right    (files/scrollback only) shift the left margin right by eight
        spaces, allowing you to view lines extending past the right
        edge of the screen.  When the left margin is other than
        zero, the indent is shown at the right edge of the status
        line.
    Left    (files/scrollback only) shift the left margin left by eight
        spaces if it is not already zero.
    Home    restart the pager.  For files and directories, you will
        be put back at the beginning of the file; for the scroll-
        back buffer, you will be placed at the end of the buffer.
    Esc    exit from the pager.

The scrollback pager adds the following keys to the above standard keys:
    M    mark the top of the region to write to a file
    W    write the marked region to a file

The dialing directory adds the following keys:
    0-9    start entering the number(s) to dial
    M    specify a telephone number to dial manually
    R    recall the last list of numbers to dial

-----------------------------------------------------------------------------
Error Messages
--------------

file not found
    RBcomm was unable to open the requested file.  This may be due to
    wildcards or a misspelling in the filename, an invalid path,
    a lack of file handles (see FILES= in your DOS manual), or a file
    sharing conflict.

invalid macro file
    the macro file you wanted to load is either corrupted or from a
    different version of RBcomm which uses an incompatible format for
    macro files.  Try recompiling the macro file with the same version
    of the compiler as the version of RBcomm you are using.

MODEM NOT RESPONDING
    RBcomm did not get an acknowledgement from the modem within four
    seconds of the last command.  If you only get this message on attack
    or list dialing, you need to increase the delay before redialing
    with RBCONFIG (under "dialing parameters")--some modems take longer
    to reset after a hangup command than others.

--out of memory--
    There was not enough memory to pop up the requested menu or prompt.
    Increase the heap size with RBCONFIG and try again.

STACK FULL
    Your macro was so deeply nested that it ran out of space.  This can
    be caused by an infinite recursion in your macro.  Increase the heap
    size with RBCONFIG (under "Other options") and try again.

-----------------------------------------------------------------------------
Warnings
--------

Don't try to load a TSR while shelled to DOS.  RBcomm won't be able to swap
itself back in and will have to abort.    Your connection will not be broken,
however.

Don't mess with the swap file while shelled.  You'll be sorry....  (RBcomm
is able to detect a missing or truncated swap file on returning, but not
other changes)

IMPORTANT:  if you are swapping to a floppy drive, DO NOT UNDER ANY
CIRCUMSTANCES replace that floppy disk while shelled to DOS or running a
file transfer.    You will definitely trash the file allocation tables and
directory of the second disk.  This is a problem with DOS itself (at least
through 3.10, later versions may have corrected it) when faced with a
diskette change while a file is open on the diskette which gets removed.
The swap file is such an open file.

-----------------------------------------------------------------------------
Known Bugs and Limitations
--------------------------

If you are using a serial port which the BIOS does not recognize, RBcomm
will most likely read garbage parameters from the port at startup, requiring
you to set the parameters by hand with Alt-P or the -P commandline option.

The pager has trouble with extremely long lines (>500 columns or so).
When encountering such a line, you may not be able to move up or down by
single lines.  PgUp and PgDn will still work, however.

RBcomm requires that the EMS page frame contain at least three pages
in order to use EMS for the scrollback and pager buffers, and at least
one page in order to swap to EMS.  This is important when running under
memory managers such as QEMM-386 which allow page frames smaller than
the standard four pages.

-----------------------------------------------------------------------------
Macro Compiler
--------------

Syntax:     MACRO srcfile [srcfile ...]
compiles each of the specified source files in turn to a macro file
with the same name and the extension .RBM.  If no extension is
specified for a source file, the default of .MAC is used.

Important Note:
    RBcomm v3.4 and later macro files are INCOMPATIBLE with
    earlier versions.  You must recompile all your macro files
    if RBcomm complains about invalid macro files.

-------------------
Macro File Commands
-------------------

Each command has the following form:

    keyname     commandword   [args]

where keyname specifies to which key the command is to be bound.  Keynames
(which are not case-sensitive) are:
    F1 through F12 for the function keys
       +F1 through +F12 for the shifted function keys
       ^F1 through ^F12 for the control function keys
       @F1 through @F12 for the alt-function keys
       @A through @Z for the alt-letter keys
       @1 through @0 for the alt-digits
       Gray+, Gray-, Gray*, Gray/ for plus, minus, star, slash keys on keypad
       @Plus and @Minus, @Gr*, @Gr/ for Alt-Gray+, Alt-Gray-, Alt-Gray* and
       Alt-Gray/
       Left, Right, Up, Down for the cursor keys on the numeric pad
       Home, End, PgUp, PgDn, Ins, and Del for the other keypad keys
       KP5 for the '5' key on the number pad (enhanced keyboard)
       ^Home, etc. for the control versions of the numberpad keys
       CP_Home     Home key on gray cursor pad
       CP_Up     Up arrow on gray cursor pad
       CP_Down     Down arrow on gray cursor pad
       CP_Enter     Enter key on cursor pad
        etc.
       @Left, @Right, @Up, @Down, @Home, @End, @PgUp, @PgDn, @Ins, @Del for
       Alt- versions of the cursor pad keys
       ^Left, ^Right, etc for Ctrl- versions of the cursor pad keys
       ^Break     for control-break
       @- @= @[ @\ @] @; @' @, @. @/ @` @* for various other Alt-keys

There are also some pseudo-keys to which you may assign a macro:
       "OnLoad" is executed any time the macro file is loaded into memory
       "AutoDL" is executed whenever the autodownload mechanism is
        initialized.  See the AUTO_XFER command for details.
       "Auto" is executed automatically when a connection is established
       "Reconnect" is executed automatically when reconnecting without
        hanging up and redialing
       "CleanUp" is executed when hanging up if carrier detect is active
       "OnAbort" is executed whenever a macro other than OnAbort aborts and
        displays the **ABORTED** message, just prior to displaying
        the message
       "Alarm" is executed whenever a connection is established with a remote
        system or when a file transfer (including TYPEing a file)
        completes.  If not bound, a simple beep is generated.

And there is a no-operation pseudo-key for use by FORCE_CLEANUP:
       "Null" does nothing and returns immediately

Finally, there are two sets of pseudo-keys which can be used to
override the default settings for file transfers.
    "#upload_x" will override the command string for the upload
        protocol with letter 'x' on the upload menu.
        Format:  #upload_z "upload command string"
    "#download_x" will override the command string for the download
        protocol with letter 'x' on the download menu.
        Format:  #download_z yes|no "download command string"
        The first parameter indicates whether or not RBcomm
        should prompt the user for a filename or parameters
        (which may be inserted in the download command using
        the %F substitution--see EXEC).

You may assign macros to control keys by specifying "^x" as the key name,
where "x" is the control key you want to use.  Similarly, you may assign a
macro to a regular key by preceding the character representing the key by a
backslash (i.e. \A for capital 'A', \a for lowercase 'a'). Note that macros
are never in effect when you are prompted for information by RBcomm; they
only affect what (if anything) gets sent to the remote system.

Finally, you may use "#nnn" where nnn is the decimal scancode of the key
to which you wish to assign the macro (values of 224 through 255 are reserved,
167 through 223 are currently unused by any key combinations supported by
the IBM ROM BIOS).

Note that the cursor pad keys will execute the binding for the
corresponding number pad key if not specifically bound (but not vice
versa).     CP_Enter defaults to the binding for @Enter.

The commandword is not case-sensitive, but you must include the underscore
if present and use the entire commandword (abbreviations are not
supported).

With the exception of the ANSWERBACK, TEST, TEXT, WAITFOR, and WHEN
commands, all commands which take a string argument pop up a prompt if the
string is empty (i.e. "").  Strings may include the following special
sequences:
    ^x   specified control character
    ^?   ASCII DEL (127)
    \a   ^G (bell)
    \b   backspace
    \e   escape
    \f   form feed
    \n   line feed
    \r   carriage return
    \t   horizontal tab
    \v   vertical tab
    \\   backslash
    \^   carat
    \0   ASCII NUL (for TEXT command only)
For character arguments, you may specify either
    'c'
where the character c is interpreted as for a string, or you may specify its
ASCII value.

Everything from a semicolon (unless it is in a string) to the end of the line
is considered a comment, as are blank lines.

If a line starts with #include rather than a key name, the specified file
will be compiled into the macro file as if it were part of the current text
file.  Note that the string is processed just like any other strings, so
that you must double any backslashes (or use forward slashes, instead).
Format:
    #INCLUDE  "d:/path/filename"
an extension of .MAC is assumed if no extension is given, and the drive
letter and path are optional (default is current drive and directory).
#INCLUDEs may be nested up to twelve deep.

If a line starts with #ignore rather than a key name, any subsequent
occurrences of the keyname following the #ignore will be ignored, just as
if you had already defined a binding for the key.  This is useful when
#include'ing a file if you do not want all the bindings in the included
file.
Format:
       #IGNORE    <keyname>

For readability, you may give names to extended keys with the
       #DEFKEY <newname> <keynumber>
command.  For example, "#defkey Proc1 199" will let you refer to
"Proc1" and "#199" interchangeably.

ABORT
    abort the current macro or operation as if the user had pressed Esc.

ABORT_UNTIL
    Abort any currently executing UNTIL command after the command(s) it
    controls complete.  If multiple UNTIL commands are nested, each is
    aborted as the commands it controls complete, until all pending
    UNTILs have been aborted.  Useful mainly in conjunction with the
    DELAYED command to provide a timeout on UNTIL loops.

    See also DELAYED, UNTIL.

ALARM
    Execute the macro bound to the "Alarm" pseudo-key.  If Alarm is not
    bound, this command is equivalent to BEEP.

    See also BEEP, SOUND.

ANSWERBACK "string"
    sets the answerback message to the specified string.  If the string is
    empty (i.e. ""), answerback is disabled (making ^E a cursor-positioning
    command), otherwise, answerback is enabled.

AT hh:mm:ss
    execute the following line (or lines if a MULTI) at the specified
    time.  If the specified time is less than the current time, the
    command(s) will be executed the next day.  The seconds may be
    omitted, in which case they default to 0.

    Note: the command(s) may actually execute later than requested if
      RBcomm is busy processing incoming characters at the time the
      command should execute.  The command will execute as soon as RBcomm
      empties its receive buffer.

    See also DELAYED, EVERY.

AUTO_XFER
    reenable autodownloads/autouploads if they have been canceled by
    an ENDWHEN ALL_XFER.  If the AutoDL pseudokey has a binding, it
    is executed; otherwise, a default routine equivalent to
        WHEN 0 "**^XB00"
           RECEIVE 'Z'
    is executed.  The command ENDWHEN ALL is implemented as an
    ENDWHEN ALL_XFER followed by AUTO_XFER.

    Further, the dialer does an ENDWHEN ALL_XFER followed by an
    AUTO_XFER, so the AutoDL pseudokey will allow autodownloads to
    be preserved across a dial attempt which does not cause a new
    macro file to be loaded.

    The autodownloads are also reenabled with AUTO_XFER when hanging
    up and immediately after loading a new macro file.

    Note: Puma autodownload may be enabled with the following lines
    as part of the AutoDL pseudokey:
        WHEN 0 "^X^H^XPuma^X^H^X"
           RECEIVE 'P'
    Although I have not yet seen MPt (the renamed Puma), I understand
    that its autodownload string has changed, requiring
        WHEN 0 "^V^H^VMPt ^V^H^V"
           RECEIVE 'P'

    WARNING: do not invoke while autodownload is enabled, as you will wind
       up invoking a download multiple times for one download request....

    See also ENDWHEN, WHEN.

AVATAR ON|OFF
    Specify whether AVATAR command sequences should be honored by
    the terminal emulator.

    See also RBCOMM_CMDS.

AWAITKEY
    pause until a key is pressed.  The next function which reads a key
    will read the key which was pressed.  Returns immediately if there
    was any typeahead (including RBcomm's key stack).

    See also KFLUSH.

BEEP
    sound the bell.     Useful mainly in conjunction with the MULTI or
    DELAYED commands (see below).

    See also ALARM, SOUND.

BREAK
    send a break to the remote system

CALL keyname
    execute the macro (if any) bound to the specified key and then continue
    executing the current macro (if inside a MULTI).

    See also GOTO_KEY, PUSHKEY.

CANCEL_DELAYED which
    cancel the specified delayed action.  Currently supported:
           ALL    cancel all delayed actions
           LAST   cancel the last executed DELAYED or EVERY.  If
                     called a second time without an intervening DELAYED
              or EVERY, the second call is ignored.

    See also DELAYED, EVERY.

CANCEL_NOTIFY
    remove the notify window immediately instead of at the end of the
    configured period of time.

CHDIR "dir"
    change the DOS default directory to the specified directory.

CLOSE_LOG
    close the current log file.  If logging is off, this command has no
    effect.
    See also OPEN_LOG, TOGGLE_LOG.

CUT num dir "search"
    search the screen backwards from the current cursor position until
    the search string (case sensitive) is found, then copy "num"
    characters in the indicated direction (AFTER or BEFORE) to the cut
    buffer.     The contents of the cut buffer remain unchanged if the search
    string is not found (in which case the completion status is set to
    FAILED for testing by IF or UNTIL).  The cut buffer may be sent to
    the remote system with the PASTE command, inserted into a line
    being edited by pressing Alt-P, or inserted with the %C variable
    expansion.

    Note that trailing blanks are deleted from the cut buffer.  In
    addition, the CUT command treats the entire screen (even if a WINDOW
    command was used to restrict output to a portion of the screen) as a
    single long line, ignoring all line wrapping for both search and cut.

    Examples:
       Screen contains "1234test5678cursor here->" and the cursor is as
       indicated.  Then
        CUT 3 BEFORE "test"
       places "234" into the cut buffer, while
        CUT 6 AFTER "test"
       places "5678cu" into the cut buffer.     Further,
        CUT 7 BEFORE ""
       will place " here->" into the cut buffer.

    See also PASTE, TRIM.

DELAYED time
    execute the macro on the next line (or lines if it is a MULTI) the
    given amount of time from now.    You may have up to six delayed
    commands active at any given time.  The maximum delay time is 18
    hours; the macro compiler will complain if you attempt to use a
    greater delay.    Times are specified as
        seconds
        minutes:seconds
    or    hours:minutes:seconds

    Note: the command may actually execute later than requested if RBcomm
      is busy processing incoming characters at the time the command should
      execute.  The command will execute as soon as RBcomm empties its
      receive buffer.

    See also CANCEL_DELAYED, EVERY, WHEN.

DIAL number redial
    dial the specified entry (0-39) from the dialing directory, or pop up
    the dialing directory if 'number' is PROMPT.  'redial' specifies how
    to dial:
        ONCE    make only one attempt
        ATTACK    try repeatedly until connected
        RECONNECT    make a single attempt if not connected, or set
            parameters and password without dialing if already
            connected

    If the number is PROMPT, the user may enter multiple numbers.  If
    'redial' is RECONNECT, all but the first number will be ignored.
    Otherwise, the entire list will be tried either once or until a
    successful connect.

    See also LISTDIAL, MDIAL.

DISPLAY "msg"
    Display the variable-expanded version (see EXEC for details) of the
    given string at the current cursor position, and update the cursor
    position to be at the end of the string.  This is similar to the
    MESSAGE command, but it always displays at the current position;
    MESSAGE also does not change the cursor position.  The characters
    ^A through ^F and ^H in the string invoke special actions.  ^C clears
    from the current position to the end of the line while ^H backs up
    one column if not already at the left edge; the other special
    characters are detailed under "Writing your own Help FIles".

    See also MESSAGE.

DVEXEC ON|OFF "DVP-command"
    Start a program in a separate DESQview window.  The first
    parameter specifies whether RBcomm should keep its serial port
    routines active; if OFF, the other program may safely perform
    serial I/O and RBcomm will wait until it terminates (if ON,
    RBcomm will continue immediately, but the new program may not
    take over the serial port interrupt without disrupting RBcomm).
    The second parameter specifies the full name of the .DVP file
    to be launched and optionally commandline parameters to
    override those stored in the .DVP.
    Example:
        DVEXEC OFF "C:/DV/OZ-PIF.DVP /X"
            might call the OZSMALL program to perform a CompuServe
        B+ file transfer, forcing its commandline to "/X"
        (meaning exit on completion).

ECHO ON|OFF
    ECHO ON forces half-duplex (local echo on) mode, ECHO OFF forces
    full-duplex (local echo off).
    (see Alt-E)

    See also STRIP_PARITY, TOGGLE_ECHO.

ENDWHEN which
    cancel the specified WHEN command.  Currently supported:
       ALL           cancel all WHENs except the autodownloads
       ALL_XFER    cancel all WHENs including the autodownloads
       LAST           cancel the last executed WHEN.  A second call without
             an intervening WHEN acts the same as ENDWHEN ALL.

    Note: ENDWHEN ALL is implemented as an ENDWHEN ALL_XFER followed
    by an AUTO_XFER.

    See also AUTO_XFER, WHEN.

EVERY delay-time repeat-interval
    execute the macro on the next line (or lines if it is a MULTI) the
    given amount of time from now, and then again every
    'repeat-interval' seconds.  You may have up to six delayed
    commands active at any given time.  The maximum delay time is 18
    hours; the macro compiler will complain if you attempt to use a
    greater delay.    The maximum repeat interval is about 3595
    seconds.  The delay time is specified as
        seconds
        minutes:seconds
    or    hours:minutes:seconds

    Note: the command may actually execute later than requested if RBcomm
      is busy processing incoming characters at the time the command should
      execute.  The command will execute as soon as RBcomm empties its
      receive buffer.

    See also CANCEL_DELAYED, DELAYED, WHEN.

EXEC "command-to-execute"
    everything up to the first blank in the string specifies the program to
    execute (the PATH will be searched if no explicit path is given, and
    both .COM and .EXE will be looked for if there is no explicit
    extension), the remainder of the string is the command tail to pass to
    the program.  Note that a following IF command will always consider
    the EXEC to have succeeded if you use COMMAND.COM to run the program
    with the construct
        "%VCOMSPEC% /c cmd"
    due to a misfeature of COMMAND.COM.

    If SAVE_SCREEN is ON, RBcomm will prompt for a key, then restore
    the screen to the state it was in before the EXEC.  No message will
    be displayed if the program returns an error; however, an error
    message will still be displayed if there was an error while attempting
    to load the program.

    Within the command, a percent sign introduces a variable substitution.
    The following sequences are supported:
        %a     hexadecimal I/O base address being used
        %C     contents of the cut buffer (see CUT and PASTE)
        %d     current date, in format mm-dd-yy
        %D     current directory, including drive
        %F     file(s) to transfer; this substitution is only meaningful
             for a file transfer parameter string, and has an undefined
         action elsewhere
        %i     IRQ number being used (0-15)
        %I     get input from user.  The following characters up to the next
         percent sign are used as the prompt and then discarded.
        %M     current macro file name
        %N     name of current remote system (from dialing directory)
        %p     port number (1-4)
        %P     port parameters, in same format as dialing directory
         display
        %s     current serial port speed
        %t     current time, in format hh:mm:ss
        %V     get an environment variable.  The following characters up to
         the next percent sign are used as the name of the variable
         and then discarded.
        %w     current switch character
        %%     a percent sign
        %/     a forward slash unless the last character of the expansion
         for the string up to this point is a slash or backslash
        %\     a backslash unless the last character of the expansion
         for the string up to this point is a slash or backslash

    See also EXECN, IF, SHELL.

EXECN  "command-to-execute"
    This command is identical to EXEC, except that no error box is
    displayed in the event of an error.  If SAVE_SCREEN is ON, the
    screen is restored without pausing for a keystroke.

    See also EXEC.

EXIT errorlevel
    End RBcomm.  Will prompt you whether or not to hang up if you are
    still connected to another system.  Returns the specified errorlevel
    to DOS; usually this should be zero, but other values may be used
    to control batch file execution.

EXPAND_BLANK ON|OFF
    Specify whether RBcomm should send a single blank instead of a
    completely blank line when TYPEing a file (see Alt-T and TYPE).
    If ON, a blank will be sent to separate two consecutive
    carriage returns (TYPE converts both CRLF and LF to CR to
    simulate keyboard input); if OFF, no extra blanks will be
    generated regardless of the data in the file.

    See also TYPE.

FDELETE "filespec"
    delete the file(s) named by filespec (which may include wildcards).
    Note that there is no confirmation requested, so use this command
    with care!!!

    See also FILES.

FILES "filespec"
    display a three-up list of the files matching the filespec.  This
    uses the file pager described above.

    See also FDELETE.

FORCE_CLEANUP keyname
    execute the following line(s), then execute the macro bound to
    "keyname" regardless of how the commands are exited (i.e. normally,
    ABORT, or <Esc>).  FORCE_CLEANUPs may be nested, in which case
    the innermost one is the only one to execute unless the cleanup
    code executes an ABORT itself (then execution gets passed to the one
    enclosing it, etc.).  If no cleanup is needed and the FORCE_CLEANUP
    is merely being used to prevent a complete abort on Esc, the pseudo-
    key Null may be used.  Null is guaranteed to perform no action and
    return immediately.

GOTO_KEY keyname
    continue execution with the specified macro (if bound).     Never returns
    to the current macro.  If the key is not bound (i.e. GOTO_KEY Null),
    execution resumes at the point from which the current macro was
    CALLed, effectively producing a return from a nested macro.

    See also CALL, PUSHKEY.

HANGUP
    hang up.  Executes macro bound to "CleanUp" before actually hanging
    up if carrier detect is active.     After hanging up, the default macro
    file is reloaded (thus cancelling any remaining WHENs and DELAYEDs).

    See also HANGUP_ONLY.

HANGUP_ONLY
    hang up, but do not execute the "CleanUp" macro or reload macro files.

    See also HANGUP.

HELP
    pop up the help screen.     If you currently have the macro file FOO
    loaded, RBcomm first attempts to read the file FOO.HLP in the RBcomm
    directory.  If it is unable to do so, it then attempts to read
    RBCOMM.HLP.

    While viewing the help screen(s), you may enter an Alt-key command.
    This will immediately exit the help system and execute the command
    right away.  If you press Alt=, that fact will be remembered, and
    the Alt= will be used to quote the next Alt-key command you press
    while in the help system.

IDLE
    go into idle mode, sending a blank followed by a backspace every 2
    minutes.  Press Esc to end idle mode.

    Both the interval and the sequence sent by idle mode may be configured
    with RBCONFIG.

IF    SUCCESS|FAILED|CONNECTED|OFFLINE|DV|NOT DV
    IF SUCCESS and IF FAILED conditionally execute a command based on the
    completion status of an immediately preceding EXEC, SHELL, SEND,
    SENDFILE, RECEIVE, RECEIVEFILE, or WAITFOR.  The following line (or
    lines if a MULTI) is executed only if that prior command was
    successful in the case of IF SUCCESS, or if it failed in the case of
    IF FAILED.

    IF CONNECTED executes the following command if carrier detect is
    asserted, while IF OFFLINE executes the following command if
    carrier detect is deasserted.

    IF DV executes the following command if RBcomm has detected that it
    is running under DESQview, while IF NOT DV executes the following
    command only if RBcomm is not running under DESQview.

    For example, if you want to execute a program only after failing to
    see a particular string, you would use

        MULTI
        WAITFOR 10 "don't run program"
        IF FAILED
            EXEC "someprog args"
        END

    See also ABORT_UNTIL, EXEC, SHELL, SEND, RECEIVE, WAITFOR, UNTIL.

KFLUSH
    empty the keyboard buffer (including RBcomm's key stack).

    See also AWAITKEY, TFLUSH.

LEARN
    start learning a macro string.    The recorded string may be sent to
    the remote system with RECALL.

    See also LOAD_MACRO, RECALL.

LISTDIAL "numbers"
    dial the specified numbers from the dialing directory repeatedly until
    a connection is established with one of the numbers.  If the empty
    string is specified, the dialing directory is popped up and the
    previous list of numbers (less the system to which RBcomm
    established a connection) is recalled.

    Each of the numbers in the list must be separated from the previous
    number by one or more spaces or commas.     For example,  "1,5 7,2 4"
    would attempt to dial entry 1, then entry 5, then 7, then 2, and
    finally entry 4 before repeating.  Any numbers in the list which are
    higher than the highest-numbered entry in the current dialing
    directory are silently skipped.

    See also DIAL, MDIAL.

LOAD_MACRO "file"
    load the specified macro file from the RBcomm directory.  If an empty
    filename is given, the user will be prompted for a name, which
    defaults to the name of the currently loaded macro file.  The current
    macro (if any) and any that it had interrupted are aborted.  However,
    if the interruption occurred during a command of extended duration
    such as a WAITFOR, that command will complete normally before the
    macro is aborted.

    See also LEARN, RECALL.

LOG "filename" "message"
    append the specified message to the named file.     Both the filename
    and the message may contain variable expansions as described under
    EXEC.  If the filename is (or expands to) the empty string "", the
    expanded message is appended to the current log file (if any).

    See also OPEN_LOG.

LOWER_DTR
    requests that DTR remain dropped after the next HANGUP or HANGUP_ONLY
    command.  The best place to put this command is in your CleanUp macro.

LTRIM CUTBUFFER "trimchars"
    remove from the left (beginning) of the cut buffer (see CUT) the
    longest sequence of characters consisting entirely of characters in
    "trimchars".  A future version of RBcomm supporting string variables
    will permit trimming more than just the cut buffer.

    Example: if a previous CUT command has placed "12  A22B  34" into the
      cut buffer, the command
          LTRIM CUTBUFFER " 1234"
      will result in "A22B  34" becoming the contents of the cut buffer,
      available for the next PASTE command or @P in the input editor.

    See also CUT, RTRIM, TRIM.

MDIAL "number" ONCE|ATTACK
    dial the specified phone number as if it had been entered as the
    manual number for the dialing directory display.

    See also DIAL, LISTDIAL.

MESSAGE row col msg
    Display the result of expanding any variables in the specified message
    (see EXEC for details) starting at the given row and column on the
    screen.     If either row or column is 255, use the current row or
    column.     Does not change the current cursor position, unlike the
    DISPLAY command.  As with DISPLAY, the characters ^A through ^F and ^H
    specify special actions.

    See also DISPLAY.

MESSAGEBOX msg
    if running under TopView or DESQview, a window with the given message
    will pop up for three seconds.    This command is ignored otherwise.

    The message has any variables expanded, and the first 40 characters
    are displayed in the pop up window.  See EXEC for the details of
    the variable expansion.

    See also NOTIFY, CANCEL_NOTIFY.

MULTI
    the following lines, up to but not including a line starting with END,
    are assigned to the specified key.  The macros assigned to the key
    may not total more than 253 bytes, and the macro compiler will
    complain if they do.

    The format of the following lines is the same as for a regular macro,
    except that you do not specify a keyname.  For example, to make
    shift-F2 switch terminal emulation to VT52, use

    +F2    MULTI
        PUSHKEY 13 0
        PUSHKEY 'V' 0
        PARAM_MENU
        END

    You may also use { and } on separate lines as synonyms for MULTI
    and END.  The braces are preferred, as MULTI/END will be phased out
    in future versions.

MUSIC ON|OFF
    specify whether ANSI music should be enabled while using the
    ANSI BBS terminal emulation.  This switch is necessary because
    the command to play music conflicts with a standard ANSI
    control sequence (Esc [ M).

    See also PLAY, SOUND.

NOTIFY    msg
    if running under TopView or DESQview, and RBcomm determines that it is
    in the background, a window with the given message will pop up for
    three seconds.    This command is ignored otherwise.

    The message has any variables expanded, and the first 40 characters
    are displayed in the pop up window.  See EXEC for the details of
    the variable expansion.

    See also CANCEL_NOTIFY, MESSAGEBOX.

OPEN_LOG  "file"
    if logging is on, the current log file will be closed.    Then, the
    specified log file will be opened (if no name is given, a prompt is
    popped up).  The same variable expansions which are valid for
    the EXEC command are applied to the filename which is given (or
    entered by the user).

    For example, to allow the environment variable RBLOG to specify the
    base name of the log file, use
        OPEN_LOG "%VRBLOG%.LOG"

    See also EXEC, CLOSE_LOG, TOGGLE_LOG, RECEIVE.

PACECHAR 'c'
    set the pace character for the TYPE command to 'c'.  RBcomm waits
    up to three seconds for the pace character when TYPEing a file to
    the remote system.  RBcomm will not wait if the pace character is
    ASCII 0 (^@).

    See also TYPE.

PARAM_MENU
    pop up the "Set Parameters" menu

PASSWORD
    send the password defined in the dialing directory.  Does not send
    a carriage return or any other terminating sequence.

    See also TEXT, TYPE.

PASTE
    send the contents of the cut buffer to the remote system.

    See also CUT.

PAUSE num-ticks
    halt execution for num-ticks/18 seconds.  Useful mainly in conjunction
    with the MULTI command (see above).

PLAY "play-string"
    play the notes specified by the string.     The string may contain
    the following directives:
        An
        Bn
        Cn
        Dn
        En
        Fn
        Gn    play the given note, 'n' specifies duration as
            a fraction of a whole note, defaults to that
            given by the last L command.  A '#' or '+'
            between the letter and 'n' produces a sharp
            note, while a '-' produces a flat note.
        Ln    specify the default length of notes as 1/n of a
            whole note
        Mx    specify music type, x=L, N, or S
            L)egato: note uses entire period
            N)ormal: note uses 7/8 of its time period
            S)taccato: note uses 3/4 of its time period
        Nn    play note number 'n', from 1 to 95
        On    specify octave number, 0 to 9.    O3 starts at
            middle C
        Pn    rest for the specified period (1/n of a whole
            note).    If 'n' is not present, use the length
            given by the last L command
        Tn    specify tempo, 32 to 255
        .    following A-G, N, or P, increases the note's
            length by 1/2.

    See also BEEP, SOUND.

PUSHKEY key scan
or
PUSHKEY keyname
    put the specified key/scancode pair onto RBcomm's internal keyboard
    stack, where the last pushed pair will be the next keystroke read
    by RBcomm.  The stack is currently eight keystrokes in size, and any
    PUSHKEY executed while the stack is full will simply be ignored.
    "keyname" may be the name of any keystroke recognized by the macro
    compiler.  <scan> is 0 for regular ASCII characters, and 1 for
    extended ASCII codes (i.e. function keys).

    Useful mainly in conjunction with the MULTI command (see above).

RBCOMM_CMDS ON|OFF
    Specify whether the terminal emulator should honor RBcomm
    private commands.

    See also AVATAR.

RECALL
    send the last string recorded with LEARN to the remote system.

    See also LEARN.

RECEIVE 'type'
    start receiving a file with the specified protocol
          0       prompt for protocol
          'A'  ASCII (capture to file--equivalent to OPEN_LOG "")
          'X'  Xmodem with parameters
          'K'  Xmodem-K with parameters
          'Y'  Ymodem
          '^Y' Ymodem with parameters
          'G'  Ymodem-G
          '^G' Ymodem-G with parameters
          'Z'  Zmodem
          '^Z' Zmodem with parameters

    See also IF, OPEN_LOG, SEND, TYPE.

RECEIVEFILE 'type' "parameters"
    start receiving using the specified protocol (which may be any of the
    ones listed for RECEIVE except 0 or 'A'), passing the specified
    parameters to the file transfer module.     Unlike RECEIVE, this command
    will not pop up any messages unless it is unable to load the file
    transfer module; in case of an error, the completion status is set
    to FAILED.

    See also RECEIVE, SENDFILE.

REPEAT times
    repeat the command on the next line (or lines if a MULTI) the specified
    number of times.

RFLUSH
    clear any characters which may still be in the serial port receive
    buffer.

    See also KFLUSH, TFLUSH.

RTRIM CUTBUFFER "trimchars"
    remove from the right (end) of the cut buffer (see CUT) the longest
    sequence of characters consisting entirely of characters in
    "trimchars".  A future version of RBcomm supporting string variables
    will permit trimming more than just the cut buffer.

    Example: if a previous CUT command has placed "12  A22B  34" into the
      cut buffer, the command
          RTRIM CUTBUFFER " 1234"
      will result in "12  A22B" becoming the contents of the cut buffer,
      available for the next PASTE command or @P in the input editor.

    See also CUT, LTRIM, TRIM.

SAVE_MACRO "file"
    no longer supported.

SAVE_SCREEN ON|OFF
    determine whether or not to save the current screen while executing
    external programs (other than file transfer).  The state of this
    flag slightly modifies the behavior of EXEC, EXECN, and SHELL.

    See also EXEC, EXECN, SHELL.

SCROLLBACK
    bring up the scrollback pager.    In addition to the standard keystrokes
    understood by the pager, 'M' marks the top of the currently displayed
    screenfull as the beginning of the region to write when 'W' is pressed.
    After pressing 'W', you will be prompted for a filename.  The section
    of the scrollback buffer between the marked top (default: beginning of
    buffer) and the bottom of the currently displayed screen is appended
    to the specified file.

SELECT_SCREEN num
    select a new screen to be the visible and active screen.  If "num" is
    PROMPT, displays a menu of the available screens.

SEND 'type'
    prepare to send a file with the specified protocol
          0       prompt for protocol
          'A'  ASCII
          'X'  Xmodem
          'K'  Xmodem-K
          'Y'  Ymodem
          'G'  Ymodem-G
          'Z'  Zmodem
    control character versions of any of the above ('^X', '^Y', etc) will
    delete the file(s) corresponding to the first filespec after sending.

    See also IF, SENDFILE, RECEIVE, TYPE.

SENDFILE 'type' "file"
    send the specified file with the given protocol, which may be any of
    the ones listed for SEND except 0 or 'A'.  Unlike SEND, this command
    will not pop up any messages unless it is unable to load the file
    transfer module; in case of an error, the completion status is set
    to FAILED.

    See also RECEIVEFILE, SEND.

SHELL
    shell to DOS.  If SAVE_SCREEN is ON, the original screen will be
    restored when you exit from the subshell.

    See also EXEC, IF.

SOUND freq dur
    Generate a tone with a frequency of <freq> Hertz for <dur> clock
    ticks (max 255).  If the frequency is 0, a musical pause of the
    specified duration is created.    If both frequency and duration are
    zero, all queued tones are discarded (applies only to DESQview at
    this time).

    See also BEEP, PLAY.

STRIP_PARITY ON|OFF
    Specify whether RBcomm should pass through the parity bit (OFF)
    or remove it before further processing (ON).  This command is
    similar to the 'P' command on the Alt-P parameters menu.

    See also ECHO.

TEST EXISTS "filespec"
    determine whether any files matching the filespec exist.  Sets the
    status to SUCCESS if at least one exists, FAILED if none.  The status
    may be checked with IF or UNTIL commands.

    See also TEST WHEN, IF.

TEST WHEN "str"
    determine whether a WHEN with the specified search string is currently
    active.     Sets the status to SUCCESS if at least one exists, FAILED if
    there are no WHENs with the specified string.  The status may be
    checked with IF or UNTIL commands.

    See also IF, WHEN, TEST EXISTS.

TEXT "msg"
    send the specified characters out the comm port.  "msg" is limited to
    253 characters.

TFLUSH
    discard any characters queued for transmission to the remote system
    which have not yet been sent.

    See also KFLUSH, RFLUSH.

TOGGLE_ECHO
    toggle the state of local echoing

    See also ECHO.

TOGGLE_LOG
    if logging is currently on, turns off logging received data to file
    if logging is off, pops up a prompt for the name of the capture file

    See also OPEN_LOG, CLOSE_LOG.

TOGGLE_VERBOSE
    toggle the state of verbose mode (see Alt-Y)

    See also VERBOSE.

TRANSLATE_BS ON|OFF
    TRANSLATE_BS ON turns on backspace/delete swapping, TRANSLATE_BS OFF
    turns it off.

TRIM CUTBUFFER "trimchars"
    remove from both beginning and end of the cut buffer (see CUT) the
    longest sequence of characters consisting entirely of characters in
    "trimchars".  A future version of RBcomm supporting string variables
    will permit trimming more than just the cut buffer.

    Example: if a previous CUT command has placed "12  A22B  34" into the
      cut buffer, the command
          TRIM CUTBUFFER " 1234"
      will result in "A22B" becoming the contents of the cut buffer,
      available for the next PASTE command or @P in the input editor.

    See also CUT, LTRIM, RTRIM.

TYPE "file"
    send the specified file to the remote system as a stream of ASCII
    characters.  Pauses at the end of each line and waits for the pace
    character to be echoed (will continue after three seconds even if
    the echo is not seen).    Equivalent to
        SEND 'A'
    if no filename is given.

    See also EXPAND_BLANK, PACECHAR, SEND.

UI_MENU
    No longer supported.  Use LOAD_MACRO "" instead.

    See also LEARN, LOAD_MACRO.

UNTIL SUCCESS|FAILED|CONNECTED|OFFLINE
    repeatedly executes the following line (or lines if a MULTI) until
    the status of the last action is either success for UNTIL SUCCESS
    or failure for UNTIL FAILED.   UNTIL CONNECTED repeatedly executes
    the following command until carrier detect becomes active, while
    UNTIL OFFLINE repeats until carrier detect drops.

    See also ABORT_UNTIL, IF.

VERBOSE ON|OFF
    VERBOSE ON turns on verbose mode, VERBOSE OFF turns off verbose mode.
    (see Alt-Y)

    See also TOGGLE_VERBOSE.

VIEW "filename"
    display the specified file one screenfull at a time.  Pops up a prompt
    if the null filename is given.

    Pressing the space bar displays the next screen, Escape exits the
    file view.

WAITFOR timeout "wait-string"
    wait up to timeout seconds for the specified string of characters to
    arrive over the comm port.  Useful mainly in conjunction with the
    MULTI command (see below).

    You may test whether the string was actually received by following
    the WAITFOR with IF SUCCESS or IF FAILED (unlike versions prior to
    3.11, a failed WAITFOR does not abort the MULTI it is a part of).

    See also IF.

WHEN    iterations "when-string"
    execute the command on the following line (or lines if it is a MULTI)
    whenever the "when-string" is encountered in the data stream coming
    from the remote system.     After the string has been encountered
    "iterations" times, the WHEN is automatically canceled (if iterations
    is zero, the WHEN must be explicitly canceled with ENDWHEN).
    You may have up to six WHENs active at any time (eight if you cancel
    the autodownload [see ENDWHEN above]).    All WHENs are canceled on
    hanging up or dialing a number, and autodownload is re-enabled.

    WHENs are tested in the order in which they were executed, so multiple
    WHENs with the same when-string will trigger in the order in which
    they were asserted.

    This can be an extremely powerful command.  For example, you can
    implement another autodownloading (or uploading!) protocol simply by
    adding
        WHEN 0 "start-string"
           EXEC "xfer-program parms"
    to the AUTO or OnLoad macro.  On CompuServe, you can make Ymodem
    autodownloading by adding
        WHEN 0 "initiate YMODEM receive"
           RECEIVE 'Y'
    to the OnLoad macro.

    The built-in Zmodem autodownload corresponds to
        WHEN 0 "**^XB00"
           RECEIVE 'Z'
    while Zmodem auto-upload can be added with
        WHEN 0 "**^XB01"
           SEND 'Z'

    The standard Puma autodownload is equivalent to the lines
        WHEN 0 "^X^H^XPuma^X^H^X"
           RECEIVE 'P'
    [thanks to Matthew Thomas for publishing his autodownload string!].

    See also DELAYED, ENDWHEN, WHENI.

WHENI    iterations "when-string"
    identical to the WHEN command, but ignores case in both the
    when-string and the incoming character stream.  Thus, a
    WHENI 0 "aBc" will match "abc", "ABC", "AbC", etc.

    See also WHEN, ENDWHEN.

WINDOW    row col width height
    limit the terminal emulator to a portion of the full screen.

    WINDOW 0 0 255 255 will restore use of the full screen regardless of
    the screen size.

Ready-Made Macro Files
----------------------

The RBcomm distribution includes the following macro files:

AVATAR.MAC    for use with a BBS that supports AVATAR emulation in
        its full-screen editor.  This file implements the so-
        called "DOORWAY mode", passing through all keystrokes.
        To access RBcomm's commands, you must use the Alt=
        escape key before the RBcomm command key.

AVATOPUS.MAC    for use with Opus 1.10 or later BBSs, or compatibles
        such as Maximus.  Implements DOORWAY mode as AVATAR.MAC
        does, but also adds logon scripts for the OPUS CBCS

BAREOPUS.MAC

CPOINT.MAC    logon to Central Point Software's BBS

DDJ.MAC        logon to M&T Publishing's BBS to access the DDJ listings

EMACS.MAC    for use with Unix systems.  Turns your Alt key into a
        Meta key.

EXAMPLES.MAC    various sample macros illustrating different features.

LK201.MAC    emulate an LK201 keyboard

OPUS.MAC

QDECK.MAC    logon to Quarterdeck's BBS

RBCOMM.MAC    default macros

VT100.MAC    emulate a VT100 keyboard

VT3270.MAC    emulate a VT100/IBM 3270 keyboard

VT52.MAC    emulate a VT52 keyboard

WORDSTAR.MAC    send WordStar motion commands using arrow keys

-----------------------------------------------------------------------------
Writing your own Help Files
---------------------------

Help files are plain ASCII files with the exception that several control
characters are used to change character attributes within a line (each
line starts with the default attributes).

    ^A  (A)lternate foreground and background colors, thus turning
        reverse video on or off
    ^B  toggle the (B)old bit
    ^D  reset to (D)efault attributes
    ^E  switch to underlined color as defined by RBCONFIG
    ^F  toggle (F)lashing (blink bit)
