SERIAL_BFIN=m or SERIAL_MUX=m shouldn't allow SERIAL_CORE_CONSOLE=y. Additionally, this patch fixes whitespace instead of tabs at the SERIAL_MUX_CONSOLE option.

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.

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 correponding port is
|
|
ready.
|
|
"earlycon=uart8250,io,0x3f8,9600n8"
|
|
"earlycon=uart8250,mmio,0xff5e0000,115200n8".
|
|
it will not only setup early console.
