# The new 8250/16550 serial drivers
config SERIAL_8250
	tristate "8250/16550 and compatible serial support"
	select SERIAL_CORE
	---help---
	  This selects whether you want to include the driver for the standard
	  serial ports.  The standard answer is Y.  People who might say N
	  here are those that are setting up dedicated Ethernet WWW/FTP
	  servers, or users that have one of the various bus mice instead of a
	  serial mouse and don't intend to use their machine's standard serial
	  port for anything.  (Note that the Cyclades and Stallion multi
	  serial port drivers do not need this driver built in for them to
	  work.)

	  To compile this driver as a module, choose M here: the
	  module will be called 8250.
	  [WARNING: Do not compile this driver as a module if you are using
	  non-standard serial ports, since the configuration information will
	  be lost when the driver is unloaded.  This limitation may be lifted
	  in the future.]

	  BTW1: If you have a mouseman serial mouse which is not recognized by
	  the X window system, try running gpm first.

	  BTW2: If you intend to use a software modem (also called Winmodem)
	  under Linux, forget it.  These modems are crippled and require
	  proprietary drivers which are only available under Windows.

	  Most people will say Y or M here, so that they can use serial mice,
	  modems and similar devices connecting to the standard serial ports.

config SERIAL_8250_CONSOLE
	bool "Console on 8250/16550 and compatible serial port"
	depends on SERIAL_8250=y
	select SERIAL_CORE_CONSOLE
	---help---
	  If you say Y here, it will be possible to use a serial port as the
	  system console (the system console is the device which receives all
	  kernel messages and warnings and which allows logins in single user
	  mode). This could be useful if some terminal or printer is connected
	  to that serial port.

	  Even if you say Y here, the currently visible virtual console
	  (/dev/tty0) will still be used as the system console by default, but
	  you can alter that using a kernel command line option such as
	  "console=ttyS1". (Try "man bootparam" or see the documentation of
	  your boot loader (grub or lilo or loadlin) about how to pass options
	  to the kernel at boot time.)

	  If you don't have a VGA card installed and you say Y here, the
	  kernel will automatically use the first serial line, /dev/ttyS0, as
	  system console.

	  You can set that using a kernel command line option such as
	  "console=uart8250,io,0x3f8,9600n8"
	  "console=uart8250,mmio,0xff5e0000,115200n8".
	  and it will switch to normal serial console when the corresponding 
	  port is ready.
	  "earlycon=uart8250,io,0x3f8,9600n8"
	  "earlycon=uart8250,mmio,0xff5e0000,115200n8".
	  it will not only setup early console.

	  If unsure, say N.

	  including serial port cards, modems, and the modem functions of
	  multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
	  credit-card size devices often used with laptops.)

	  To compile this driver as a module, choose M here: the

config SERIAL_8250_NR_UARTS

	  Set this to the number of serial ports you want the driver

	  Set this to the maximum number of serial ports you want

	  8250.nr_uarts

config SERIAL_8250_EXTENDED
	bool "Extended 8250/16550 serial driver options"
	depends on SERIAL_8250
	help
	  If you wish to use any non-standard features of the standard "dumb"
	  driver, say Y here. This includes HUB6 support, shared serial
	  interrupts, special multiport support, support for more than the
	  four COM 1/2/3/4 boards, etc.

	  Note that the answer to this question won't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about serial driver options. If unsure, say N.

config SERIAL_8250_MANY_PORTS
	bool "Support more than 4 legacy serial ports"
	depends on SERIAL_8250_EXTENDED && !IA64
	help
	  Say Y here if you have dumb serial boards other than the four
	  standard COM 1/2/3/4 ports. This may happen if you have an AST
	  FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
	  from <http://www.tldp.org/docs.html#howto>), or other custom
	  serial port hardware which acts similar to standard serial port
	  hardware. If you only use the standard COM 1/2/3/4 ports, you can
	  say N here to save some memory. You can also say Y if you have an
	  "intelligent" multiport card such as Cyclades, Digiboards, etc.
