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

183 comment "Unix98 PTY support"
186 bool "Unix98 PTY support"
188 A pseudo terminal (PTY) is a software device consisting of two
189 halves: a master and a slave. The slave device behaves identical to
190 a physical terminal; the master device is used by a process to
191 read data from and write data to the slave, thereby emulating a
192 terminal. Typical programs for the master side are telnet servers
195 Linux has traditionally used the BSD-like names /dev/ptyxx for
196 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
197 has a number of problems. The GNU C library glibc 2.1 and later,
198 however, supports the Unix98 naming standard: in order to acquire a
199 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
200 terminal is then made available to the process and the pseudo
201 terminal slave can be accessed as /dev/pts/<number>. What was
202 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
204 The entries in /dev/pts/ are created on the fly by a virtual
205 file system; therefore, if you say Y here you should say Y to
206 "/dev/pts file system for Unix98 PTYs" as well.
208 If you want to say Y here, you need to have the C library glibc 2.1
209 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
210 Read the instructions in <file:Documentation/Changes> pertaining to
211 pseudo terminals. It's safe to say N.
