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

174
175 Unlike KDB's disable_nmi command, with this driver you are always
176 able to go back to the debugger using KGDB escape sequence ($3#33).
177 This is because this console driver processes the input in NMI
178 context, and thus is able to intercept the magic sequence.
179
180 Note that since the console interprets input and uses polling
181 communication methods, for things like PPP you still must fully
182 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
183 use raw console.
