If you say Y here, you will get support for terminal devices with
|
|
display and keyboard devices. These are called "virtual" because you
|
|
can run several virtual terminals (also called virtual consoles) on
|
|
one physical terminal. This is rather useful, for example one
|
|
virtual terminal can collect system messages and warnings, another
|
|
one can be used for a text-mode user session, and a third could run
|
|
an X session, all in parallel. Switching between virtual terminals
|
|
is done with certain key combinations, usually Alt-<function key>.
|
|
|
|
The setterm command ("man setterm") can be used to change the
|
|
properties (such as colors or beeping) of a virtual terminal. The
|
|
man page console_codes(4) ("man console_codes") contains the special
|
|
character sequences that can be used to change those properties
|
|
directly. The fonts used on virtual terminals can be changed with
|
|
the setfont ("man setfont") command and the key bindings are defined
|
|
with the loadkeys ("man loadkeys") command.
|
|
|
|
You need at least one virtual terminal device in order to make use
|
|
of your keyboard and monitor. Therefore, only people configuring an
|
|
embedded system would want to say N here in order to save some
|
|
memory; the only way to log into such a system is then via a serial
|
|
or network connection.
|
|
|
|
If unsure, say Y, or else you won't be able to do much with your new
|

shiny Linux system :-)

The system console is the device which receives all kernel messages
|
|
and warnings and which allows logins in single user mode. If you
|
|
answer Y here, a virtual terminal (the device used to interact with
|
|
a physical terminal) can be used as system console. This is the most
|
|
common mode of operations, so you should say Y here unless you want
|
|
the kernel messages be output only to a serial port (in which case
|
|
you should say Y to "Console on serial port", below).
|
|
|
|
If you do say Y here, by default the currently visible virtual
|
|
terminal (/dev/tty0) will be used as system console. You can change
|
|
that with a kernel command line option such as "console=tty3" which
|
|
would use the third virtual terminal as system console. (Try "man
|
|
bootparam" or see the documentation of your boot loader (lilo or
|
|
loadlin) about how to pass options to the kernel at boot time.)

The virtual terminal is the device that interacts with the physical
|
|
terminal through console drivers. On these systems, at least one
|
|
console driver is loaded. In other configurations, additional console
|
|
drivers may be enabled, such as the framebuffer console. If more than
|
|
1 console driver is enabled, setting this to 'y' will allow you to
|

select the console driver that will serve as the backend for the

virtual terminals.

Digiboards, etc. These are usually used for systems that need many

serial ports because they serve many terminals or dial-in

Note that the answer to this question won't directly affect the

---help---
|

If you intend to attach a printer to the parallel port of your Linux
|

box (as opposed to using a serial printer; if the connector at the
|
|
printer has 9 or 25 holes ["female"], then it's serial), say Y.
|
|
Also read the Printing-HOWTO, available from
|
|
<http://www.tldp.org/docs.html#howto>.
|
|
|
|
It is possible to share one parallel port among several devices
|
|
(e.g. printer and ZIP drive) and it is safe to compile the
|
|
corresponding drivers into the kernel.
|
|
|
|
To compile this driver as a module, choose M here and read
|
|
<file:Documentation/parport.txt>. The module will be called lp.
|
|
|
|
If you have several parallel ports, you can specify which ports to
|
|
use with the "lp" kernel command line option. (Try "man bootparam"
|
|
or see the documentation of your boot loader (lilo or loadlin) about
|
|
how to pass options to the kernel at boot time.) The syntax of the
|
|
"lp" command line option can be found in <file:drivers/char/lp.c>.
|
|
|
|
If you have more than 8 printers, you need to increase the LP_NO
|
|
macro in lp.c and the PARPORT_MAX macro in parport.h.

---help---

If you want kernel messages to be printed out as they occur, you
|
|
can have a console on the printer. This option adds support for
|
|
doing that; to actually get it to happen you need to pass the
|
|
option "console=lp0" to the kernel at boot time.
|
|
|
|
If the printer is out of paper (or off, or unplugged, or too
|
|
busy..) the kernel will stall until the printer is ready again.
|
|
By defining CONSOLE_LP_STRICT to 0 (at your own risk) you
|
|
can make the kernel continue when this happens,
|
|
but it'll lose the kernel messages.
