| Unlike KDB's disable_nmi command, with this driver you are always | |

| 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. | |
