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

 176
 177 config UNIX98_PTYS
 178         bool "Unix98 PTY support"
 179         ---help---
 180           A pseudo terminal (PTY) is a software device consisting of two
 181           halves: a master and a slave. The slave device behaves identical to
 182           a physical terminal; the master device is used by a process to
 183           read data from and write data to the slave, thereby emulating a
 184           terminal. Typical programs for the master side are telnet servers
 185           and xterms.
 186
 187           Linux has traditionally used the BSD-like names /dev/ptyxx for
 188           masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
 189           has a number of problems. The GNU C library glibc 2.1 and later,
 190           however, supports the Unix98 naming standard: in order to acquire a
 191           pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
 192           terminal is then made available to the process and the pseudo
 193           terminal slave can be accessed as /dev/pts/<number>. What was
 194           traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
 195
 196           The entries in /dev/pts/ are created on the fly by a virtual
 197           file system; therefore, if you say Y here you should say Y to
 198           "/dev/pts file system for Unix98 PTYs" as well.
 199
 200           If you want to say Y here, you need to have the C library glibc 2.1
 201           or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
 202           Read the instructions in <file:Documentation/Changes> pertaining to
 203           pseudo terminals. It's safe to say N.

 205 config UNIX98_PTY_COUNT
 206         int "Maximum number of Unix98 PTYs in use (0-2048)"

 208         default "256"
 209         help
 210           The maximum number of Unix98 PTYs that can be used at any one time.
 211           The default is 256, and should be enough for desktop systems. Server
 212           machines which support incoming telnet/rlogin/ssh connections and/or
 213           serve several X terminals may want to increase this: every incoming
 214           connection and every xterm uses up one PTY.
 215
 216           When not in use, each additional set of 256 PTYs occupy
 217           approximately 8 KB of kernel memory on 32-bit architectures.
