87 config VT
88 bool "Virtual terminal"
89 ---help---
90 If you say Y here, you will get support for terminal devices with
91 display and keyboard devices. These are called "virtual" because you
92 can run several virtual terminals (also called virtual consoles) on
93 one physical terminal. This is rather useful, for example one
94 virtual terminal can collect system messages and warnings, another
95 one can be used for a text-mode user session, and a third could run
96 an X session, all in parallel. Switching between virtual terminals
97 is done with certain key combinations, usually Alt-<function key>.
99 The setterm command ("man setterm") can be used to change the
100 properties (such as colors or beeping) of a virtual terminal. The
101 man page console_codes(4) ("man console_codes") contains the special
102 character sequences that can be used to change those properties
103 directly. The fonts used on virtual terminals can be changed with
104 the setfont ("man setfont") command and the key bindings are defined
105 with the loadkeys ("man loadkeys") command.
107 You need at least one virtual terminal device in order to make use
108 of your keyboard and monitor. Therefore, only people configuring an
109 embedded system would want to say N here in order to save some
110 memory; the only way to log into such a system is then via a serial
111 or network connection.
113 If unsure, say Y, or else you won't be able to do much with your new
114 shiny Linux system :-)
116 config VT_CONSOLE
117 bool "Support for console on virtual terminal"
118 depends on VT
119 ---help---
120 The system console is the device which receives all kernel messages
121 and warnings and which allows logins in single user mode. If you
122 answer Y here, a virtual terminal (the device used to interact with
123 a physical terminal) can be used as system console. This is the most
124 common mode of operations, so you should say Y here unless you want
125 the kernel messages be output only to a serial port (in which case
126 you should say Y to "Console on serial port", below).
128 If you do say Y here, by default the currently visible virtual
129 terminal (/dev/tty0) will be used as system console. You can change
130 that with a kernel command line option such as "console=tty3" which
131 would use the third virtual terminal as system console. (Try "man
132 bootparam" or see the documentation of your boot loader (lilo or
133 loadlin) about how to pass options to the kernel at boot time.)
135 If unsure, say Y.

142 comment "Unix98 PTY support"
144 config UNIX98_PTYS
145 bool "Unix98 PTY support"
146 ---help---
147 A pseudo terminal (PTY) is a software device consisting of two
148 halves: a master and a slave. The slave device behaves identical to
149 a physical terminal; the master device is used by a process to
150 read data from and write data to the slave, thereby emulating a
151 terminal. Typical programs for the master side are telnet servers
152 and xterms.
154 Linux has traditionally used the BSD-like names /dev/ptyxx for
155 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
156 has a number of problems. The GNU C library glibc 2.1 and later,
157 however, supports the Unix98 naming standard: in order to acquire a
158 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
159 terminal is then made available to the process and the pseudo
160 terminal slave can be accessed as /dev/pts/<number>. What was
161 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
163 The entries in /dev/pts/ are created on the fly by a virtual
164 file system; therefore, if you say Y here you should say Y to
165 "/dev/pts file system for Unix98 PTYs" as well.
167 If you want to say Y here, you need to have the C library glibc 2.1
168 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
169 Read the instructions in <file:Documentation/Changes> pertaining to
170 pseudo terminals. It's safe to say N.
172 config UNIX98_PTY_COUNT
173 int "Maximum number of Unix98 PTYs in use (0-2048)"
174 depends on UNIX98_PTYS
175 default "256"
176 help
177 The maximum number of Unix98 PTYs that can be used at any one time.
178 The default is 256, and should be enough for desktop systems. Server
179 machines which support incoming telnet/rlogin/ssh connections and/or
180 serve several X terminals may want to increase this: every incoming
181 connection and every xterm uses up one PTY.
183 When not in use, each additional set of 256 PTYs occupy
184 approximately 8 KB of kernel memory on 32-bit architectures.
