102config VT
103 bool "Virtual terminal"
104 ---help---
105 If you say Y here, you will get support for terminal devices with
106 display and keyboard devices. These are called "virtual" because you
107 can run several virtual terminals (also called virtual consoles) on
108 one physical terminal. This is rather useful, for example one
109 virtual terminal can collect system messages and warnings, another
110 one can be used for a text-mode user session, and a third could run
111 an X session, all in parallel. Switching between virtual terminals
112 is done with certain key combinations, usually Alt-<function key>.
113
114 The setterm command ("man setterm") can be used to change the
115 properties (such as colors or beeping) of a virtual terminal. The
116 man page console_codes(4) ("man console_codes") contains the special
117 character sequences that can be used to change those properties
118 directly. The fonts used on virtual terminals can be changed with
119 the setfont ("man setfont") command and the key bindings are defined
120 with the loadkeys ("man loadkeys") command.
121
122 You need at least one virtual terminal device in order to make use
123 of your keyboard and monitor. Therefore, only people configuring an
124 embedded system would want to say N here in order to save some
125 memory; the only way to log into such a system is then via a serial
126 or network connection.
127
128 If unsure, say Y, or else you won't be able to do much with your new
129 shiny Linux system :-)
130
131config VT_CONSOLE
132 bool "Support for console on virtual terminal"
133 depends on VT
134 ---help---
135 The system console is the device which receives all kernel messages
136 and warnings and which allows logins in single user mode. If you
137 answer Y here, a virtual terminal (the device used to interact with
138 a physical terminal) can be used as system console. This is the most
139 common mode of operations, so you should say Y here unless you want
140 the kernel messages be output only to a serial port (in which case
141 you should say Y to "Console on serial port", below).
142
143 If you do say Y here, by default the currently visible virtual
144 terminal (/dev/tty0) will be used as system console. You can change
145 that with a kernel command line option such as "console=tty3" which
146 would use the third virtual terminal as system console. (Try "man
147 bootparam" or see the documentation of your boot loader (lilo or
148 loadlin) about how to pass options to the kernel at boot time.)
149
150 If unsure, say Y.

158
159config UNIX98_PTYS
160 bool "Unix98 PTY support"
161 ---help---
162 A pseudo terminal (PTY) is a software device consisting of two
163 halves: a master and a slave. The slave device behaves identical to
164 a physical terminal; the master device is used by a process to
165 read data from and write data to the slave, thereby emulating a
166 terminal. Typical programs for the master side are telnet servers
167 and xterms.
168
169 Linux has traditionally used the BSD-like names /dev/ptyxx for
170 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
171 has a number of problems. The GNU C library glibc 2.1 and later,
172 however, supports the Unix98 naming standard: in order to acquire a
173 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
174 terminal is then made available to the process and the pseudo
175 terminal slave can be accessed as /dev/pts/<number>. What was
176 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
177
178 The entries in /dev/pts/ are created on the fly by a virtual
179 file system; therefore, if you say Y here you should say Y to
180 "/dev/pts file system for Unix98 PTYs" as well.
181
182 If you want to say Y here, you need to have the C library glibc 2.1
183 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
184 Read the instructions in <file:Documentation/Changes> pertaining to
185 pseudo terminals. It's safe to say N.
186
187config UNIX98_PTY_COUNT
188 int "Maximum number of Unix98 PTYs in use (0-2048)"
189 depends on UNIX98_PTYS
190 default "256"
191 help
192 The maximum number of Unix98 PTYs that can be used at any one time.
193 The default is 256, and should be enough for desktop systems. Server
194 machines which support incoming telnet/rlogin/ssh connections and/or
195 serve several X terminals may want to increase this: every incoming
196 connection and every xterm uses up one PTY.
197
198 When not in use, each additional set of 256 PTYs occupy
199 approximately 8 KB of kernel memory on 32-bit architectures.
