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

 145           external 8250/16C550 compatible UARTs.
 146           The ttySn nodes are legally reserved for the 8250 serial driver
 147           but are often misused by other serial drivers.
 148

 150           /dev/, and pass "console=ttyATn" to the kernel.

 158           This special driver allows you to temporary use NMI debugger port
 159           as a normal console (assuming that the port is attached to KGDB).
 160
 161           Unlike KDB's disable_nmi command, with this driver you are always
 162           able to go back to the debugger using KGDB escape sequence ($3#33).
 163           This is because this console driver processes the input in NMI
 164           context, and thus is able to intercept the magic sequence.
 165
 166           Note that since the console interprets input and uses polling
 167           communication methods, for things like PPP you still must fully
 168           detach debugger port from the KGDB NMI (i.e. disable_nmi), and
 169           use raw console.

 827           The pmac_zilog driver for the z85C30 chip on many powermacs

 830           the two drivers being unable to coexist; you could not use
