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

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

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