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.

840 The pmac_zilog driver for the z85C30 chip on many powermacs
841 historically used the device numbers for /dev/ttySn. The
842 8250 serial port driver also uses these numbers, which means
843 the two drivers being unable to coexist; you could not use
844 both z85C30 and 8250 type ports at the same time.
845
846 If this option is not selected, the pmac_zilog driver will
847 use the device numbers allocated for /dev/ttyPZn. This allows
848 the pmac_zilog and 8250 drivers to co-exist, but may cause
849 existing userspace setups to break. Programs that need to
850 access the built-in serial ports on powermacs will need to
851 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
852
853 If you enable this option, any z85c30 ports in the system will

1493 This driver supports the Comtrol RocketPort EXPRESS and
1494 RocketPort INFINITY families of PCI/PCIe multiport serial adapters.
1495 These adapters use a "RocketPort 2" ASIC that is not compatible
1496 with the original RocketPort driver (CONFIG_ROCKETPORT).
1497
1498 To compile this driver as a module, choose M here: the
1499 module will be called rp2.
1500
1501 If you want to compile this driver into the kernel, say Y here. If
1502 you don't have a suitable RocketPort card installed, say N.
