184 This special driver allows you to temporary use NMI debugger port
185 as a normal console (assuming that the port is attached to KGDB).
186
187 Unlike KDB's disable_nmi command, with this driver you are always
188 able to go back to the debugger using KGDB escape sequence ($3#33).
189 This is because this console driver processes the input in NMI
190 context, and thus is able to intercept the magic sequence.
191
192 Note that since the console interprets input and uses polling
193 communication methods, for things like PPP you still must fully
194 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
195 use raw console.
