* 2001-01-30 KJO (vac4050@cae597.rsc.raytheon.com):
* Fixed rtems_monitor_command_lookup() to accept partial
* commands to uniqeness. Added support for setting
* the monitor prompt via an environment variable:
* RTEMS_MONITOR_PROMPT
*
* CCJ: 26-3-2000, adding command history and command line
* editing. This code is donated from My Right Boot and not
* covered by GPL, only the RTEMS license.
