PROBOARD.EXE accepts following command line parameters:

PROBOARD [-B<baud>] [-P<port>] [-N<node>] [-L<level]
         [-T<time>] [-S] [-Q] [-X] [-V<mode>]

These parameters have the following meaning:

 (-)
 -B<baud>   Specifies the baud rate. You can specify the
            following baud rates: 300, 1200/75 2400, 4800, 7200,
            9600, 12000, 14400, 16800, 19200, 21600, 24000,
            26400, 28800, 38400, 57600, 64000, and 115200.
 -P<port>   Specifies the com-port (1-8).
 -N<node>   This node's node number (1-255).
 -L<level>  Prevents people with a security level lower than this level
            to access this node.  Great for only allowing subscribing
            user access to one or more nodes.
 -T<time>   <time> is the time until the next event in minutes.  Useful
            with FrontDoor's DOBBS batch file.
 -S         Start ProBoard in stand alone mode.  ProBoard will use as a
            default the PORT and the BAUD specified in your
            configuration, but you can override them by using the
            -P<port> and the -B<baud> command line parameters along
            with the -S parameter.
 -Q         Quiet mode.  Great if your BBS is in a location such as
            your bedroom etc.  The only noise ProBoard will make is
            playing the ATTEN.MUS file (if a user who has this set in
            their user record logs on), and playing the PAGE tune when
            a user pages during valid paging hours.
 -X         Tells ProBoard not to use EMS.
 -V<mode>   Runs ProBoard in video mode <mode>. This can be useful if
            you have a monitor capable of displaying 132 columns, and
            you would like to run ProBoard in such a mode (you will
            see an extra information window on your screen if
            ProBoard is run in 132 cols mode). The <mode> parameter
            is a decimal number specifying the video mode, as it is
            used with INT 10H, function 00. (only programmers will
            understand this though :-).  This is different for every
            video card.

When no '-B<x>' and no '-S' parameter is given, ProBoard will be started in local mode.

ProBoard returns an errorlevel when a user has logged off.

The errorlevels of PROBOARD.EXE are:

   0    Everything OK, normal logoff.
   1    FATAL error, something 'terrible' happened, or the
        modem could not be initialized.
   2    Not used.
   3    Netmail entered by the user.
   4    Echomail entered by the user.
   5    Echomail AND Netmail entered by the user.
  99    SysOp pressed <Esc> at the "Waiting for call" screen.
 100    ProBoard was requested to go down by a semaphore file.
