110config VT
111 bool "Virtual terminal"
112 ---help---
113 If you say Y here, you will get support for terminal devices with
114 display and keyboard devices. These are called "virtual" because you
115 can run several virtual terminals (also called virtual consoles) on
116 one physical terminal. This is rather useful, for example one
117 virtual terminal can collect system messages and warnings, another
118 one can be used for a text-mode user session, and a third could run
119 an X session, all in parallel. Switching between virtual terminals
120 is done with certain key combinations, usually Alt-<function key>.
121
122 The setterm command ("man setterm") can be used to change the
123 properties (such as colors or beeping) of a virtual terminal. The
124 man page console_codes(4) ("man console_codes") contains the special
125 character sequences that can be used to change those properties
126 directly. The fonts used on virtual terminals can be changed with
127 the setfont ("man setfont") command and the key bindings are defined
128 with the loadkeys ("man loadkeys") command.
129
130 You need at least one virtual terminal device in order to make use
131 of your keyboard and monitor. Therefore, only people configuring an
132 embedded system would want to say N here in order to save some
133 memory; the only way to log into such a system is then via a serial
134 or network connection.
135
136 If unsure, say Y, or else you won't be able to do much with your new
137 shiny Linux system :-)
138
139config VT_CONSOLE
140 bool "Support for console on virtual terminal"
141 depends on VT
142 ---help---
143 The system console is the device which receives all kernel messages
144 and warnings and which allows logins in single user mode. If you
145 answer Y here, a virtual terminal (the device used to interact with
146 a physical terminal) can be used as system console. This is the most
147 common mode of operations, so you should say Y here unless you want
148 the kernel messages be output only to a serial port (in which case
149 you should say Y to "Console on serial port", below).
150
151 If you do say Y here, by default the currently visible virtual
152 terminal (/dev/tty0) will be used as system console. You can change
153 that with a kernel command line option such as "console=tty3" which
154 would use the third virtual terminal as system console. (Try "man
155 bootparam" or see the documentation of your boot loader (lilo or
156 loadlin) about how to pass options to the kernel at boot time.)
157
158 If unsure, say Y.

166
167config UNIX98_PTYS
168 bool "Unix98 PTY support"
169 ---help---
170 A pseudo terminal (PTY) is a software device consisting of two
171 halves: a master and a slave. The slave device behaves identical to
172 a physical terminal; the master device is used by a process to
173 read data from and write data to the slave, thereby emulating a
174 terminal. Typical programs for the master side are telnet servers
175 and xterms.
176
177 Linux has traditionally used the BSD-like names /dev/ptyxx for
178 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
179 has a number of problems. The GNU C library glibc 2.1 and later,
180 however, supports the Unix98 naming standard: in order to acquire a
181 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
182 terminal is then made available to the process and the pseudo
183 terminal slave can be accessed as /dev/pts/<number>. What was
184 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
185
186 The entries in /dev/pts/ are created on the fly by a virtual
187 file system; therefore, if you say Y here you should say Y to
188 "/dev/pts file system for Unix98 PTYs" as well.
189
190 If you want to say Y here, you need to have the C library glibc 2.1
191 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
192 Read the instructions in <file:Documentation/Changes> pertaining to
193 pseudo terminals. It's safe to say N.
194
195config UNIX98_PTY_COUNT
196 int "Maximum number of Unix98 PTYs in use (0-2048)"
197 depends on UNIX98_PTYS
198 default "256"
199 help
200 The maximum number of Unix98 PTYs that can be used at any one time.
201 The default is 256, and should be enough for desktop systems. Server
202 machines which support incoming telnet/rlogin/ssh connections and/or
203 serve several X terminals may want to increase this: every incoming
204 connection and every xterm uses up one PTY.
205
206 When not in use, each additional set of 256 PTYs occupy
207 approximately 8 KB of kernel memory on 32-bit architectures.
