170 external 8250/16C550 compatible UARTs.
171 The ttySn nodes are legally reserved for the 8250 serial driver
172 but are often misused by other serial drivers.
173
174 To use this, you should create suitable ttyATn device nodes in
175 /dev/, and pass "console=ttyATn" to the kernel.

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