Support can be enabled for 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
|
| 251 |
|
|
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.
