	  Unlike KDB's disable_nmi command, with this driver you are always
	  able to go back to the debugger using KGDB escape sequence ($3#33).
	  This is because this console driver processes the input in NMI
	  context, and thus is able to intercept the magic sequence.

	  Note that since the console interprets input and uses polling
	  communication methods, for things like PPP you still must fully
	  detach debugger port from the KGDB NMI (i.e. disable_nmi), and
	  use raw console.

	  This driver supports the Comtrol RocketPort EXPRESS and
	  RocketPort INFINITY families of PCI/PCIe multiport serial adapters.
	  These adapters use a "RocketPort 2" ASIC that is not compatible
	  with the original RocketPort driver (CONFIG_ROCKETPORT).

	  To compile this driver as a module, choose M here: the
	  module will be called rp2.

	  If you want to compile this driver into the kernel, say Y here.  If
	  you don't have a suitable RocketPort card installed, say N.

	  If multiple cards are present, the default limit of 32 ports may
	  need to be increased.
