--=== South B*R*O*N*X & Environment Variables ===--

    The environment in which South B*R*O*N*X was written supports COM 1-4 on 
    the standard IRQ's - COM1/COM3 = IRQ4 and COM2/COM4 = IRQ3. 

    If you wish to use a non-standard IRQ, add the IRQ number after the 
    configuration filename. 

    For instance:) 

    Let's assume your Door is called BRONX and you want to use COM1 and IRQ5. 
    The command line your BRONX.BAT file has to pass to the Door would be:
    BRONX BRONX.CFG /5  

    or

    BRONX BRONX.CFG /%IRQ% for the environment variable.

    The /5 tells DoorFrame to use IRQ5 rather than the standard IRQ4 that
    is normally used with COM1. 

    No /x parameter is needed for the standard IRQ's.
    

    If you wish to use run the game on a multi-node set-up you will have to
    have one .cfg file and likley a .bat for each node specifing the details 
    used by that particular node depending on what your BBS platform requires.
