593 If you say Y here, it will be possible to use a serial port as the
594 system console (the system console is the device which receives all
595 kernel messages and warnings and which allows logins in single user
596 mode). This could be useful if some terminal or printer is connected
597 to that serial port.
598
599 Even if you say Y here, the currently visible virtual console
600 (/dev/tty0) will still be used as the system console by default, but
601 you can alter that using a kernel command line option such as
602 "console=ttyS1". (Try "man bootparam" or see the documentation of
603 your boot loader (lilo or loadlin) about how to pass options to the
604 kernel at boot time.)
605
606 If you don't have a VGA card installed and you say Y here, the
607 kernel will automatically use the first serial line, /dev/ttyS0, as
608 system console.
609
610 If unsure, say N.
