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

819 The pmac_zilog driver for the z85C30 chip on many powermacs
820 historically used the device numbers for /dev/ttySn. The
821 8250 serial port driver also uses these numbers, which means

823 both z85C30 and 8250 type ports at the same time.
824
825 If this option is not selected, the pmac_zilog driver will
826 use the device numbers allocated for /dev/ttyPZn. This allows
827 the pmac_zilog and 8250 drivers to co-exist, but may cause
828 existing userspace setups to break. Programs that need to
829 access the built-in serial ports on powermacs will need to
830 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
