7 * This file is inspired in rtems_monitor & Chris John MyRightBoot
8 *
9 * But I want to make it more user friendly
10 * A 'monitor' command is added to adapt the call rtems monitor commands
11 * at my call procedure
12 *
13 * MINIX date.c is adapted to run here. Like a exercise only....
14 *
15 * TODO: A lot of improvements of course.
16 *      cat, cp, rm, mv, ...
17 *      hexdump,
18 *     
19 *      More? Say me it, please...
20 *     
21 *      The BSP Specific are not welcome here.
22 *     
23 * C&S welcome...
