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

 150           This special driver allows you to temporary use NMI debugger port
 151           as a normal console (assuming that the port is attached to KGDB).
 152
 153           Unlike KDB's disable_nmi command, with this driver you are always
 154           able to go back to the debugger using KGDB escape sequence ($3#33).
 155           This is because this console driver processes the input in NMI
 156           context, and thus is able to intercept the magic sequence.
 157
 158           Note that since the console interprets input and uses polling
 159           communication methods, for things like PPP you still must fully
 160           detach debugger port from the KGDB NMI (i.e. disable_nmi), and
 161           use raw console.

 820           The pmac_zilog driver for the z85C30 chip on many powermacs
 821           historically used the device numbers for /dev/ttySn.  The

 823           the two drivers being unable to coexist; you could not use
 824           both z85C30 and 8250 type ports at the same time.
