124config VT
125 bool "Virtual terminal"
126 ---help---
127 If you say Y here, you will get support for terminal devices with
128 display and keyboard devices. These are called "virtual" because you
129 can run several virtual terminals (also called virtual consoles) on
130 one physical terminal. This is rather useful, for example one
131 virtual terminal can collect system messages and warnings, another
132 one can be used for a text-mode user session, and a third could run
133 an X session, all in parallel. Switching between virtual terminals
134 is done with certain key combinations, usually Alt-<function key>.
135
136 The setterm command ("man setterm") can be used to change the
137 properties (such as colors or beeping) of a virtual terminal. The
138 man page console_codes(4) ("man console_codes") contains the special
139 character sequences that can be used to change those properties
140 directly. The fonts used on virtual terminals can be changed with
141 the setfont ("man setfont") command and the key bindings are defined
142 with the loadkeys ("man loadkeys") command.
143
144 You need at least one virtual terminal device in order to make use
145 of your keyboard and monitor. Therefore, only people configuring an
146 embedded system would want to say N here in order to save some
147 memory; the only way to log into such a system is then via a serial
148 or network connection.
149
150 If unsure, say Y, or else you won't be able to do much with your new
151 shiny Linux system :-)

153config VT_CONSOLE
154 bool "Support for console on virtual terminal"
155 depends on VT
156 ---help---
157 The system console is the device which receives all kernel messages
158 and warnings and which allows logins in single user mode. If you
159 answer Y here, a virtual terminal (the device used to interact with
160 a physical terminal) can be used as system console. This is the most
161 common mode of operations, so you should say Y here unless you want
162 the kernel messages be output only to a serial port (in which case
163 you should say Y to "Console on serial port", below).
164
165 If you do say Y here, by default the currently visible virtual
166 terminal (/dev/tty0) will be used as system console. You can change
167 that with a kernel command line option such as "console=tty3" which
168 would use the third virtual terminal as system console. (Try "man
169 bootparam" or see the documentation of your boot loader (lilo or
170 loadlin) about how to pass options to the kernel at boot time.)
171
172 If unsure, say Y.

181config UNIX98_PTYS
182 bool "Unix98 PTY support"
183 ---help---
184 A pseudo terminal (PTY) is a software device consisting of two
185 halves: a master and a slave. The slave device behaves identical to
186 a physical terminal; the master device is used by a process to
187 read data from and write data to the slave, thereby emulating a
188 terminal. Typical programs for the master side are telnet servers
189 and xterms.
190
191 Linux has traditionally used the BSD-like names /dev/ptyxx for
192 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
193 has a number of problems. The GNU C library glibc 2.1 and later,
194 however, supports the Unix98 naming standard: in order to acquire a
195 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
196 terminal is then made available to the process and the pseudo
197 terminal slave can be accessed as /dev/pts/<number>. What was
198 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
199
200 The entries in /dev/pts/ are created on the fly by a virtual
201 file system; therefore, if you say Y here you should say Y to
202 "/dev/pts file system for Unix98 PTYs" as well.
203
204 If you want to say Y here, you need to have the C library glibc 2.1
205 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
206 Read the instructions in <file:Documentation/Changes> pertaining to
207 pseudo terminals. It's safe to say N.
