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

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

  132. config UNIX98_PTYS
  133. bool "Unix98 PTY support"
  134. ---help---
  135. A pseudo terminal (PTY) is a software device consisting of two
  136. halves: a master and a slave. The slave device behaves identical to
  137. a physical terminal; the master device is used by a process to
  138. read data from and write data to the slave, thereby emulating a
  139. terminal. Typical programs for the master side are telnet servers
  140. and xterms.
  141. Linux has traditionally used the BSD-like names /dev/ptyxx for
  142. masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
  143. has a number of problems. The GNU C library glibc 2.1 and later,
  144. however, supports the Unix98 naming standard: in order to acquire a
  145. pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
  146. terminal is then made available to the process and the pseudo
  147. terminal slave can be accessed as /dev/pts/<number>. What was
  148. traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
  149. The entries in /dev/pts/ are created on the fly by a virtual
  150. file system; therefore, if you say Y here you should say Y to
  151. "/dev/pts file system for Unix98 PTYs" as well.
  152. If you want to say Y here, you need to have the C library glibc 2.1
  153. or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
  154. Read the instructions in <file:Documentation/Changes> pertaining to
  155. pseudo terminals. It's safe to say N.
  156. config UNIX98_PTY_COUNT

  159. default "256"
  160. help
  161. The maximum number of Unix98 PTYs that can be used at any one time.
  162. The default is 256, and should be enough for desktop systems. Server
  163. machines which support incoming telnet/rlogin/ssh connections and/or
  164. serve several X terminals may want to increase this: every incoming
  165. connection and every xterm uses up one PTY.
  166. When not in use, each additional set of 256 PTYs occupy
  167. approximately 8 KB of kernel memory on 32-bit architectures.
