            Support can be enabled for three different varieties of ROM monitor.

            This support changes various eCos semantics such as the encoding

            of diagnostic output, or the overriding of hardware interrupt

            vectors.

            Firstly there is \"Generic\" support which prevents the HAL

            from overriding the hardware vectors that it does not use, to

            instead allow an installed ROM monitor to handle them. This is

            the most basic support which is likely to be common to most

            implementations of ROM monitor.

            \"CygMon\" provides support for the Cygnus ROM Monitor.

            And finally, \"GDB_stubs\" provides support when GDB stubs are

            included in the ROM monitor or boot ROM."
