 124 config VT
 125         bool "Virtual terminal"
 126         ---help---
 127           If you say Y here, you will get support for terminal devices with
 128           display and keyboard devices. These are called "virtual" because you
 129           can run several virtual terminals (also called virtual consoles) on
 130           one physical terminal. This is rather useful, for example one
 131           virtual terminal can collect system messages and warnings, another
 132           one can be used for a text-mode user session, and a third could run
 133           an X session, all in parallel. Switching between virtual terminals
 134           is done with certain key combinations, usually Alt-<function key>.
 135
 136           The setterm command ("man setterm") can be used to change the
 137           properties (such as colors or beeping) of a virtual terminal. The
 138           man page console_codes(4) ("man console_codes") contains the special
 139           character sequences that can be used to change those properties
 140           directly. The fonts used on virtual terminals can be changed with
 141           the setfont ("man setfont") command and the key bindings are defined
 142           with the loadkeys ("man loadkeys") command.
 143
 144           You need at least one virtual terminal device in order to make use
 145           of your keyboard and monitor. Therefore, only people configuring an
 146           embedded system would want to say N here in order to save some
 147           memory; the only way to log into such a system is then via a serial
 148           or network connection.
 149
 150           If unsure, say Y, or else you won't be able to do much with your new
 151           shiny Linux system :-)
 152
 153 config VT_CONSOLE
 154         bool "Support for console on virtual terminal"
 155         depends on VT
 156         ---help---
 157           The system console is the device which receives all kernel messages
 158           and warnings and which allows logins in single user mode. If you
 159           answer Y here, a virtual terminal (the device used to interact with
 160           a physical terminal) can be used as system console. This is the most
 161           common mode of operations, so you should say Y here unless you want
 162           the kernel messages be output only to a serial port (in which case
 163           you should say Y to "Console on serial port", below).
 164
 165           If you do say Y here, by default the currently visible virtual
 166           terminal (/dev/tty0) will be used as system console. You can change
 167           that with a kernel command line option such as "console=tty3" which
 168           would use the third virtual terminal as system console. (Try "man
 169           bootparam" or see the documentation of your boot loader (lilo or
 170           loadlin) about how to pass options to the kernel at boot time.)
 171
 172           If unsure, say Y.

 181 config UNIX98_PTYS
 182         bool "Unix98 PTY support"
 183         ---help---
 184           A pseudo terminal (PTY) is a software device consisting of two
 185           halves: a master and a slave. The slave device behaves identical to
 186           a physical terminal; the master device is used by a process to
 187           read data from and write data to the slave, thereby emulating a
 188           terminal. Typical programs for the master side are telnet servers
 189           and xterms.
 190
 191           Linux has traditionally used the BSD-like names /dev/ptyxx for
 192           masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
 193           has a number of problems. The GNU C library glibc 2.1 and later,
 194           however, supports the Unix98 naming standard: in order to acquire a
 195           pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
 196           terminal is then made available to the process and the pseudo
 197           terminal slave can be accessed as /dev/pts/<number>. What was
 198           traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
 199
 200           The entries in /dev/pts/ are created on the fly by a virtual
 201           file system; therefore, if you say Y here you should say Y to
 202           "/dev/pts file system for Unix98 PTYs" as well.
 203
 204           If you want to say Y here, you need to have the C library glibc 2.1
 205           or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
 206           Read the instructions in <file:Documentation/Changes> pertaining to
 207           pseudo terminals. It's safe to say N.
