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