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.

819           The pmac_zilog driver for the z85C30 chip on many powermacs
