160           The ttySn nodes are legally reserved for the 8250 serial driver

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.
