 153           instead of the normal /dev/ttySn (major 4, minor starting at

 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.
