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

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