  486. If you say Y here, it will be possible to use a serial port as the
  487. system console (the system console is the device which receives all
  488. kernel messages and warnings and which allows logins in single user
  489. mode). This could be useful if some terminal or printer is connected
  490. to that serial port.
  491. Even if you say Y here, the currently visible virtual console
  492. (/dev/tty0) will still be used as the system console by default, but
  493. you can alter that using a kernel command line option such as
  494. "console=ttyS1". (Try "man bootparam" or see the documentation of
  495. your boot loader (lilo or loadlin) about how to pass options to the
  496. kernel at boot time.)
  497. If you don't have a VGA card installed and you say Y here, the
  498. kernel will automatically use the first serial line, /dev/ttyS0, as
  499. system console.
  500. If unsure, say N.
