+       help
+         This special driver allows you to temporary use NMI debugger port
+         as a normal console (assuming that the port is attached to KGDB).
+
+         Unlike KDB's disable_nmi command, with this driver you are always
+         able to go back to the debugger using KGDB escape sequence ($3#33).
+         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.
+
+         If unsure, say N.
