  26         help
  27           If you say Y here, it will be possible to use a USB to serial
  28           converter port as the system console (the system console is the
  29           device which receives all kernel messages and warnings and which
  30           allows logins in single user mode). This could be useful if some
  31           terminal or printer is connected to that serial port.
  32
  33           Even if you say Y here, the currently visible virtual console
  34           (/dev/tty0) will still be used as the system console by default, but
  35           you can alter that using a kernel command line option such as
  36           "console=ttyUSB0". (Try "man bootparam" or see the documentation of
  37           your boot loader (lilo or loadlin) about how to pass options to the
  38           kernel at boot time.)
  39
  40           If you don't have a VGA card installed and you say Y here, the
  41           kernel will automatically use the first USB to serial converter
  42           port, /dev/ttyUSB0, as system console.

  44           If unsure, say N.
