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

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