394 If you say Y here, it will be possible to use a serial port as the

397 mode). This could be useful if some terminal or printer is connected
398 to that serial port.
399
400 Even if you say Y here, the currently visible virtual console
401 (/dev/tty0) will still be used as the system console by default, but
402 you can alter that using a kernel command line option such as
403 "console=ttyS1". (Try "man bootparam" or see the documentation of
404 your boot loader (silo) about how to pass options to the kernel at
405 boot time.)
406
407 If you don't have a graphics card installed and you say Y here, the
408 kernel will automatically use the first serial line, /dev/ttyS0, as
