662 ---help---
663 If you say Y here, it will be possible to use a serial port as the
664 system console (the system console is the device which receives all
665 kernel messages and warnings and which allows logins in single user
666 mode). This could be useful if some terminal or printer is connected
667 to that serial port.
668
669 Even if you say Y here, the currently visible virtual console
670 (/dev/tty0) will still be used as the system console by default, but
671 you can alter that using a kernel command line option such as
672 "console=ttyS1". (Try "man bootparam" or see the documentation of
673 your boot loader (lilo or loadlin) about how to pass options to the
674 kernel at boot time.)
675
676 If you don't have a VGA card installed and you say Y here, the
677 kernel will automatically use the first serial line, /dev/ttyS0, as
678 system console.
679
680 If unsure, say N.
