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

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

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

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

 826           The pmac_zilog driver for the z85C30 chip on many powermacs

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