159	  external 8250/16C550 compatible UARTs.
160	  The ttySn nodes are legally reserved for the 8250 serial driver
161	  but are often misused by other serial drivers.
162

172	  This special driver allows you to temporary use NMI debugger port
173	  as a normal console (assuming that the port is attached to KGDB).
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.
