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

171	  This special driver allows you to temporary use NMI debugger port
172	  as a normal console (assuming that the port is attached to KGDB).
173
174	  Unlike KDB's disable_nmi command, with this driver you are always
175	  able to go back to the debugger using KGDB escape sequence ($3#33).
176	  This is because this console driver processes the input in NMI
177	  context, and thus is able to intercept the magic sequence.
178
179	  Note that since the console interprets input and uses polling
180	  communication methods, for things like PPP you still must fully
181	  detach debugger port from the KGDB NMI (i.e. disable_nmi), and
182	  use raw console.
