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

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.
