| This is because this console driver processes the input in NMI |
| context, and thus is able to intercept the magic sequence. |
| |
| Note that since the console interprets input and uses polling |
| communication methods, for things like PPP you still must fully |
| detach debugger port from the KGDB NMI (i.e. disable_nmi), and |
| use raw console. |
