95config VT
96 bool "Virtual terminal"
97 ---help---
98 If you say Y here, you will get support for terminal devices with
99 display and keyboard devices. These are called "virtual" because you
100 can run several virtual terminals (also called virtual consoles) on
101 one physical terminal. This is rather useful, for example one
102 virtual terminal can collect system messages and warnings, another
103 one can be used for a text-mode user session, and a third could run
104 an X session, all in parallel. Switching between virtual terminals
105 is done with certain key combinations, usually Alt-<function key>.
106
107 The setterm command ("man setterm") can be used to change the
108 properties (such as colors or beeping) of a virtual terminal. The
109 man page console_codes(4) ("man console_codes") contains the special
110 character sequences that can be used to change those properties
111 directly. The fonts used on virtual terminals can be changed with
112 the setfont ("man setfont") command and the key bindings are defined
113 with the loadkeys ("man loadkeys") command.
114
115 You need at least one virtual terminal device in order to make use
116 of your keyboard and monitor. Therefore, only people configuring an
117 embedded system would want to say N here in order to save some
118 memory; the only way to log into such a system is then via a serial
119 or network connection.
120
121 If unsure, say Y, or else you won't be able to do much with your new
122 shiny Linux system :-)
123
124config VT_CONSOLE
125 bool "Support for console on virtual terminal"
126 depends on VT
127 ---help---
128 The system console is the device which receives all kernel messages
129 and warnings and which allows logins in single user mode. If you
130 answer Y here, a virtual terminal (the device used to interact with
131 a physical terminal) can be used as system console. This is the most
132 common mode of operations, so you should say Y here unless you want
133 the kernel messages be output only to a serial port (in which case
134 you should say Y to "Console on serial port", below).
135
136 If you do say Y here, by default the currently visible virtual
137 terminal (/dev/tty0) will be used as system console. You can change
138 that with a kernel command line option such as "console=tty3" which
139 would use the third virtual terminal as system console. (Try "man
140 bootparam" or see the documentation of your boot loader (lilo or
141 loadlin) about how to pass options to the kernel at boot time.)
142
143 If unsure, say Y.

151
152config UNIX98_PTYS
153 bool "Unix98 PTY support"
154 ---help---
155 A pseudo terminal (PTY) is a software device consisting of two
156 halves: a master and a slave. The slave device behaves identical to
157 a physical terminal; the master device is used by a process to
158 read data from and write data to the slave, thereby emulating a
159 terminal. Typical programs for the master side are telnet servers
160 and xterms.
161
162 Linux has traditionally used the BSD-like names /dev/ptyxx for
163 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
164 has a number of problems. The GNU C library glibc 2.1 and later,
165 however, supports the Unix98 naming standard: in order to acquire a
166 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
167 terminal is then made available to the process and the pseudo
168 terminal slave can be accessed as /dev/pts/<number>. What was
169 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
170
171 The entries in /dev/pts/ are created on the fly by a virtual
172 file system; therefore, if you say Y here you should say Y to
173 "/dev/pts file system for Unix98 PTYs" as well.
174
175 If you want to say Y here, you need to have the C library glibc 2.1
176 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
177 Read the instructions in <file:Documentation/Changes> pertaining to
178 pseudo terminals. It's safe to say N.

180config UNIX98_PTY_COUNT
181 int "Maximum number of Unix98 PTYs in use (0-2048)"
182 depends on UNIX98_PTYS
183 default "256"
184 help
185 The maximum number of Unix98 PTYs that can be used at any one time.
186 The default is 256, and should be enough for desktop systems. Server
187 machines which support incoming telnet/rlogin/ssh connections and/or
188 serve several X terminals may want to increase this: every incoming
189 connection and every xterm uses up one PTY.
190
191 When not in use, each additional set of 256 PTYs occupy
192 approximately 8 KB of kernel memory on 32-bit architectures.
