  15           This selects whether you want to include the driver for the standard
  16           serial ports.  The standard answer is Y.  People who might say N
  17           here are those that are setting up dedicated Ethernet WWW/FTP
  18           servers, or users that have one of the various bus mice instead of a
  19           serial mouse and don't intend to use their machine's standard serial
  20           port for anything.  (Note that the Cyclades and Stallion multi
  21           serial port drivers do not need this driver built in for them to
  22           work.)
  23
  24           To compile this driver as a module, choose M here: the
  25           module will be called 8250.
  26           [WARNING: Do not compile this driver as a module if you are using
  27           non-standard serial ports, since the configuration information will
  28           be lost when the driver is unloaded.  This limitation may be lifted
  29           in the future.]
  30
  31           BTW1: If you have a mouseman serial mouse which is not recognized by
  32           the X window system, try running gpm first.
  33
  34           BTW2: If you intend to use a software modem (also called Winmodem)
  35           under Linux, forget it.  These modems are crippled and require
  36           proprietary drivers which are only available under Windows.
  37
  38           Most people will say Y or M here, so that they can use serial mice,
  39           modems and similar devices connecting to the standard serial ports.

  44         select SERIAL_CORE_CONSOLE
  45         ---help---
  46           If you say Y here, it will be possible to use a serial port as the
  47           system console (the system console is the device which receives all
  48           kernel messages and warnings and which allows logins in single user
  49           mode). This could be useful if some terminal or printer is connected
  50           to that serial port.
  51
  52           Even if you say Y here, the currently visible virtual console
  53           (/dev/tty0) will still be used as the system console by default, but
  54           you can alter that using a kernel command line option such as
  55           "console=ttyS1". (Try "man bootparam" or see the documentation of
  56           your boot loader (grub or lilo or loadlin) about how to pass options
  57           to the kernel at boot time.)
  58
  59           If you don't have a VGA card installed and you say Y here, the
  60           kernel will automatically use the first serial line, /dev/ttyS0, as
  61           system console.
  62
  63           You can set that using a kernel command line option such as
  64           "console=uart8250,io,0x3f8,9600n8"
  65           "console=uart8250,mmio,0xff5e0000,115200n8".
  66           and it will switch to normal serial console when the corresponding
  67           port is ready.
  68           "earlycon=uart8250,io,0x3f8,9600n8"
  69           "earlycon=uart8250,mmio,0xff5e0000,115200n8".
  70           it will not only setup early console.
