-config VT
- bool "Virtual terminal"
- ---help---
- 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

- 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

- port for anything. (Note that the Cyclades and Stallion multi
- serial port drivers do not need this driver built in for them to
- work.)
-
- To compile this driver as a module, choose M here: the

- [WARNING: Do not compile this driver as a module if you are using
- non-standard serial ports, since the configuration information will
- be lost when the driver is unloaded. This limitation may be lifted
- in the future.]
-
- BTW1: If you have a mouseman serial mouse which is not recognized by
- the X window system, try running gpm first.
-
- BTW2: If you intend to use a software modem (also called Winmodem)
- under Linux, forget it. These modems are crippled and require

- on the CPU model) standard Linux tty devices, /dev/ttySC[012]; one
- of these is normally used as the system console.
-

-
-config SERIAL_CONSOLE

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

- mode). This could be useful if some terminal or printer is connected
- to that serial port.
-
- Even if you say Y here, the currently visible virtual console
- (/dev/tty0) will still be used as the system console by default, but
- you can alter that using a kernel command line option such as
- "console=ttyS1". (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.)
-
- If you don't have a VGA card installed and you say Y here, the
- kernel will automatically use the first serial line, /dev/ttyS0, as
- system console.
-
- If unsure, say N.

-
-config UNIX98_PTYS
- bool "Unix98 PTY support"
- ---help---
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
- The entries in /dev/pts/ are created on the fly by a virtual
- file system; therefore, if you say Y here you should say Y to
- "/dev/pts file system for Unix98 PTYs" as well.
-
- If you want to say Y here, you need to have the C library glibc 2.1
- or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
- Read the instructions in <file:Documentation/Changes> pertaining to
- pseudo terminals. It's safe to say N.

- machines which support incoming telnet/rlogin/ssh connections and/or

- Also read the Printing-HOWTO, available from

-
- It is possible to share one parallel port among several devices

- 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>.

- 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,

- port, for instance deviceid (which displays Plug-and-Play device
- IDs).
-
- This is the parallel port equivalent of SCSI generic support (sg).
- It is safe to say N to this -- it is not needed for normal printing
- or parallel port CD-ROM/disk support.

-
-config PSMOUSE
- bool "PS/2 mouse (aka \"auxiliary device\") support"
- ---help---
- The PS/2 mouse connects to a special mouse port that looks much like
- the keyboard port (small circular connector with 6 pins). This way,
- the mouse does not use any serial ports. This port can also be used
- for other input devices like light pens, tablets, keypads. Compaq,
- AST and IBM all use this as their mouse port on currently shipping
- machines. The trackballs of some laptops are PS/2 mice also. In
- particular, the C&T 82C710 mouse on TI Travelmates is a PS/2 mouse.
-
- Although PS/2 mice are not technically bus mice, they are explained
- in detail in the Busmouse-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- When using a PS/2 mouse, you can get problems if you want to use the
- mouse both on the Linux console and under X. Using the "-R" option
- of the Linux mouse managing program gpm (available from
- <ftp://gnu.systemy.it/pub/gpm/>) solves this problem, or you can get
- the "mconv2" utility from <ftp://ibiblio.org/pub/Linux/system/mouse/>.
