159 The ttySn nodes are legally reserved for the 8250 serial driver
160 but are often misused by other serial drivers.

168 bool "Serial console over KGDB NMI debugger port"
169 depends on KGDB_SERIAL_CONSOLE
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.

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.

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.
