150 This special driver allows you to temporary use NMI debugger port

152
153 Unlike KDB's disable_nmi command, with this driver you are always
154 able to go back to the debugger using KGDB escape sequence ($3#33).
155 This is because this console driver processes the input in NMI
156 context, and thus is able to intercept the magic sequence.
157
158 Note that since the console interprets input and uses polling
159 communication methods, for things like PPP you still must fully
160 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
161 use raw console.
