            Support can be enabled for three different varieties of ROM monitor.
215
            This support changes various eCos semantics such as the encoding
216
            of diagnostic output, or the overriding of hardware interrupt
217
            vectors.
218
            Firstly there is \"Generic\" support which prevents the HAL
219
            from overriding the hardware vectors that it does not use, to
220
            instead allow an installed ROM monitor to handle them. This is
221
            the most basic support which is likely to be common to most
222
            implementations of ROM monitor.
223
            \"GDB_stubs\" provides support when GDB stubs are included in
224
            the ROM monitor or boot ROM.
225
            And finally, \"PMON\" allows the program to co-operate with
