  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. To compile this driver as a module, choose M here: the
  24. module will be called 8250.
  25. [WARNING: Do not compile this driver as a module if you are using
  26. non-standard serial ports, since the configuration information will
  27. be lost when the driver is unloaded. This limitation may be lifted
  28. in the future.]
  29. BTW1: If you have a mouseman serial mouse which is not recognized by
  30. the X window system, try running gpm first.
  31. BTW2: If you intend to use a software modem (also called Winmodem)
  32. under Linux, forget it. These modems are crippled and require
  33. proprietary drivers which are only available under Windows.
  34. Most people will say Y or M here, so that they can use serial mice,
  35. modems and similar devices connecting to the standard serial ports.

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