113 bool "Virtual terminal"
115 If you say Y here, you will get support for terminal devices with
116 display and keyboard devices. These are called "virtual" because you
117 can run several virtual terminals (also called virtual consoles) on
118 one physical terminal. This is rather useful, for example one
119 virtual terminal can collect system messages and warnings, another
120 one can be used for a text-mode user session, and a third could run
121 an X session, all in parallel. Switching between virtual terminals
122 is done with certain key combinations, usually Alt-<function key>.
124 The setterm command ("man setterm") can be used to change the
125 properties (such as colors or beeping) of a virtual terminal. The
126 man page console_codes(4) ("man console_codes") contains the special
127 character sequences that can be used to change those properties
128 directly. The fonts used on virtual terminals can be changed with
129 the setfont ("man setfont") command and the key bindings are defined
130 with the loadkeys ("man loadkeys") command.
132 You need at least one virtual terminal device in order to make use
133 of your keyboard and monitor. Therefore, only people configuring an
134 embedded system would want to say N here in order to save some
135 memory; the only way to log into such a system is then via a serial
136 or network connection.
138 If unsure, say Y, or else you won't be able to do much with your new
139 shiny Linux system :-)
142 bool "Support for console on virtual terminal"
145 The system console is the device which receives all kernel messages
146 and warnings and which allows logins in single user mode. If you
147 answer Y here, a virtual terminal (the device used to interact with
148 a physical terminal) can be used as system console. This is the most
149 common mode of operations, so you should say Y here unless you want
150 the kernel messages be output only to a serial port (in which case
151 you should say Y to "Console on serial port", below).
153 If you do say Y here, by default the currently visible virtual
154 terminal (/dev/tty0) will be used as system console. You can change
155 that with a kernel command line option such as "console=tty3" which
156 would use the third virtual terminal as system console. (Try "man
157 bootparam" or see the documentation of your boot loader (lilo or
158 loadlin) about how to pass options to the kernel at boot time.)
167 comment "Unix98 PTY support"
170 bool "Unix98 PTY support"
172 A pseudo terminal (PTY) is a software device consisting of two
173 halves: a master and a slave. The slave device behaves identical to
174 a physical terminal; the master device is used by a process to
175 read data from and write data to the slave, thereby emulating a
176 terminal. Typical programs for the master side are telnet servers
179 Linux has traditionally used the BSD-like names /dev/ptyxx for
180 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
181 has a number of problems. The GNU C library glibc 2.1 and later,
182 however, supports the Unix98 naming standard: in order to acquire a
183 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
184 terminal is then made available to the process and the pseudo
185 terminal slave can be accessed as /dev/pts/<number>. What was
186 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
188 The entries in /dev/pts/ are created on the fly by a virtual
189 file system; therefore, if you say Y here you should say Y to
190 "/dev/pts file system for Unix98 PTYs" as well.
192 If you want to say Y here, you need to have the C library glibc 2.1
193 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
194 Read the instructions in <file:Documentation/Changes> pertaining to
195 pseudo terminals. It's safe to say N.
