GT supports several types of doors.  All are optional, though you
will probably wish to use at least the Shell Door for yourself.


a)  Automatic doors - if you create a suitable batch file, GT will hand 
    control to it when it reaches the appropriate stage.

        GTLOGON.BAT     executed every time a caller logs on.

        GTNLOGON.BAT    executed when a NEW user logs on

        GTLOGOFF.BAT    executed every time a caller logs off

        GTNLOGOFF.BAT   executed when a NEW user logs on

    The automatic doors could allow you to install alternative 
    mailcheckers and perform administrative functions not already 
    written into GT.


b)  Selectable doors

        Selected by the caller from the door menu, which appears when
        executing the <o>pen door command.

        Typically used for playing games and running other external
        programs.


c)  The DOS shell door.

        This gives you as sysop COMMAND.COM access when calling in from
        remote (and is also used if you execute the <S>hell command while
        testing locally).
