155 external 8250/16C550 compatible UARTs.
156 The ttySn nodes are legally reserved for the 8250 serial driver
157 but are often misused by other serial drivers.
158
159 To use this, you should create suitable ttyATn device nodes in
160 /dev/, and pass "console=ttyATn" to the kernel.

168 This special driver allows you to temporary use NMI debugger port
169 as a normal console (assuming that the port is attached to KGDB).
170
171 Unlike KDB's disable_nmi command, with this driver you are always
172 able to go back to the debugger using KGDB escape sequence ($3#33).
173 This is because this console driver processes the input in NMI
174 context, and thus is able to intercept the magic sequence.
175
176 Note that since the console interprets input and uses polling
177 communication methods, for things like PPP you still must fully
178 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
179 use raw console.
