137	  external 8250/16C550 compatible UARTs.
138	  The ttySn nodes are legally reserved for the 8250 serial driver
139	  but are often misused by other serial drivers.

150	  This special driver allows you to temporary use NMI debugger port
151	  as a normal console (assuming that the port is attached to KGDB).
152
153	  Unlike KDB's disable_nmi command, with this driver you are always
154	  able to go back to the debugger using KGDB escape sequence ($3#33).
155	  This is because this console driver processes the input in NMI
156	  context, and thus is able to intercept the magic sequence.
157
158	  Note that since the console interprets input and uses polling
159	  communication methods, for things like PPP you still must fully
160	  detach debugger port from the KGDB NMI (i.e. disable_nmi), and
161	  use raw console.
