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 serial.
[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.
If unsure, say N.
config SERIAL_8250_HCDP
bool "Console device discovery via EFI HCDP table"
depends on IA64
depends on SERIAL_8250_CONSOLE=y
---help---
If you wish to make the serial console port described by the EFI
HCDP table available for use as serial console, say Y here. See
<http://www.dig64.org/specifications/DIG64_HCDPv10a_01.pdf>.
config SERIAL_8250_CS
tristate "8250/16550 PCMCIA device support"
depends on PCMCIA && SERIAL_8250
---help---
Say Y here to enable support for 16-bit PCMCIA serial devices,
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
module will be called serial_cs.
If unsure, say N.
config SERIAL_8250_ACPI
bool "8250/16550 device discovery via ACPI namespace"
default y if IA64
depends on ACPI_BUS && SERIAL_8250
---help---
If you wish to enable serial port discovery via the ACPI
namespace, say Y here. If unsure, say N.
config SERIAL_8250_NR_UARTS
int "Maximum number of non-legacy 8250/16550 serial ports"
depends on SERIAL_8250
default "4"
---help---
Set this to the number of non-legacy serial ports you want
the driver to support. This includes any ports discovered
via ACPI or PCI enumeration and any ports that may be added
at run-time via hot-plug.
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.
config SERIAL_8250_SHARE_IRQ
bool "Support for sharing serial interrupts"
depends on SERIAL_8250_EXTENDED
help
Some serial boards have hardware support which allows multiple dumb
serial ports on the same board to share a single IRQ. To enable
support for this in the serial driver, say Y here.
config SERIAL_8250_DETECT_IRQ
bool "Autodetect IRQ on standard ports (unsafe)"
depends on SERIAL_8250_EXTENDED
help
Say Y here if you want the kernel to try to guess which IRQ
to use for your serial port.
This is considered unsafe; it is far better to configure the IRQ in
a boot script using the setserial command.
If unsure, say N.
config SERIAL_8250_MULTIPORT
bool "Support special multiport boards"
depends on SERIAL_8250_EXTENDED
help
Some multiport serial ports have special ports which are used to
signal when there are any serial ports on the board which need
servicing. Say Y here to enable the serial driver to take advantage
of those special I/O ports.

need to be completed to use the Serial MUX:
1. create the device entry (mknod /dev/ttyB0 c 11 0)
2. Edit the /etc/inittab to start a getty listening on /dev/ttyB0
3. Add device ttyB0 to /etc/securetty (if you want to log on as
