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

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

843 both z85C30 and 8250 type ports at the same time.
844
845 If this option is not selected, the pmac_zilog driver will
846 use the device numbers allocated for /dev/ttyPZn. This allows
847 the pmac_zilog and 8250 drivers to co-exist, but may cause
848 existing userspace setups to break. Programs that need to
849 access the built-in serial ports on powermacs will need to
850 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
