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

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

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