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

  40. If you say Y here, it will be possible to use a serial port as the
  41. system console (the system console is the device which receives all
  42. kernel messages and warnings and which allows logins in single user
  43. mode). This could be useful if some terminal or printer is connected
  44. to that serial port.
  45. Even if you say Y here, the currently visible virtual console
  46. (/dev/tty0) will still be used as the system console by default, but
  47. you can alter that using a kernel command line option such as
  48. "console=ttyS1". (Try "man bootparam" or see the documentation of
  49. your boot loader (grub or lilo or loadlin) about how to pass options
  50. to the kernel at boot time.)
  51. If you don't have a VGA card installed and you say Y here, the
  52. kernel will automatically use the first serial line, /dev/ttyS0, as
  53. system console.
