| for applications, console 12 is reserved for kernel console. Pressing |
| function keys F1-F12 switches between the consoles. |

| If the architecture supports framebuffer device larger with |
| resolution at least 800x600, nice graphical console is shown. At the top |
| of the screen a row of buttons for the virtual console is drawn. If |
| the button contains console number, an application is connected to it. |
| The red button signifies that there was an activity on the terminal |
| since it was last shown to the user. |

| \section{KConsole} |
| KConsole is a kernel thread operating completely in priviledged mode. |
| It allows user to interact directly with the kernel and even start directly |

| The mips, ia32 and amd64 platforms provide additional commands regarding |
| debugging facility - set and clear hardware breakpoints and watchpoints. |

| \section{KConsole Task Control} |
| KConsole {\em call} commands can be used to start and kill the tasks. |
| To repeatably start the task, the following procedure should be used: |
| \begin{verbatim} |
| .... kernel boot data .... |
| init[8].addr=0x8027b000, init[8].size=86016 |
| .... rest of boot data ... |
| kconsole> call2 task_run_program 0x8027b000 0 |
| Calling f(0x8027b000,0): 0x80119283: generic/src/proc/task.o:task_run_program |
| Result: 0x80086500 |
| \end{verbatim} |
| |
| To kill a task, the function {\em task\_kill} is appropriate. The {\em taskid} |
| parameter is a 64-bit number on all platforms, thus on the 32-bit platforms |
| call2 should be used with 2 32-bit parameters instead. |
| \begin{verbatim} |
| kconsole> call2 task_kill 8 0 |
| Calling f(0x8,0x0): 0x801197e8: generic/src/proc/task.o:task_kill |
| Result: 0x0 |
| \end{verbatim} |

| It may happen that the IPC communication dies or that there appear some |
| problems in the communication chain |
