74 bool "Virtual terminal"
76 If you say Y here, you will get support for terminal devices with
77 display and keyboard devices. These are called "virtual" because you
78 can run several virtual terminals (also called virtual consoles) on
79 one physical terminal. This is rather useful, for example one
80 virtual terminal can collect system messages and warnings, another
81 one can be used for a text-mode user session, and a third could run
82 an X session, all in parallel. Switching between virtual terminals
83 is done with certain key combinations, usually Alt-<function key>.
85 The setterm command ("man setterm") can be used to change the
86 properties (such as colors or beeping) of a virtual terminal. The
87 man page console_codes(4) ("man console_codes") contains the special
88 character sequences that can be used to change those properties
89 directly. The fonts used on virtual terminals can be changed with
90 the setfont ("man setfont") command and the key bindings are defined
91 with the loadkeys ("man loadkeys") command.
93 You need at least one virtual terminal device in order to make use
94 of your keyboard and monitor. Therefore, only people configuring an
95 embedded system would want to say N here in order to save some
96 memory; the only way to log into such a system is then via a serial
97 or network connection.
99 If unsure, say Y, or else you won't be able to do much with your new
100 shiny Linux system :-)
103 bool "Support for console on virtual terminal"
106 The system console is the device which receives all kernel messages
107 and warnings and which allows logins in single user mode. If you
108 answer Y here, a virtual terminal (the device used to interact with
109 a physical terminal) can be used as system console. This is the most
110 common mode of operations, so you should say Y here unless you want
111 the kernel messages be output only to a serial port (in which case
112 you should say Y to "Console on serial port", below).
114 If you do say Y here, by default the currently visible virtual
115 terminal (/dev/tty0) will be used as system console. You can change
116 that with a kernel command line option such as "console=tty3" which
117 would use the third virtual terminal as system console. (Try "man
118 bootparam" or see the documentation of your boot loader (lilo or
119 loadlin) about how to pass options to the kernel at boot time.)

128 comment "Unix98 PTY support"
131 bool "Unix98 PTY support"
133 A pseudo terminal (PTY) is a software device consisting of two
134 halves: a master and a slave. The slave device behaves identical to
135 a physical terminal; the master device is used by a process to
136 read data from and write data to the slave, thereby emulating a
137 terminal. Typical programs for the master side are telnet servers
140 Linux has traditionally used the BSD-like names /dev/ptyxx for
141 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
142 has a number of problems. The GNU C library glibc 2.1 and later,
143 however, supports the Unix98 naming standard: in order to acquire a
144 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
145 terminal is then made available to the process and the pseudo
146 terminal slave can be accessed as /dev/pts/<number>. What was
147 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
149 The entries in /dev/pts/ are created on the fly by a virtual
150 file system; therefore, if you say Y here you should say Y to
151 "/dev/pts file system for Unix98 PTYs" as well.
153 If you want to say Y here, you need to have the C library glibc 2.1
154 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
155 Read the instructions in <file:Documentation/Changes> pertaining to
156 pseudo terminals. It's safe to say N.
158 config UNIX98_PTY_COUNT
159 int "Maximum number of Unix98 PTYs in use (0-2048)"
160 depends on UNIX98_PTYS
163 The maximum number of Unix98 PTYs that can be used at any one time.
164 The default is 256, and should be enough for desktop systems. Server
165 machines which support incoming telnet/rlogin/ssh connections and/or
166 serve several X terminals may want to increase this: every incoming
167 connection and every xterm uses up one PTY.
169 When not in use, each additional set of 256 PTYs occupy
170 approximately 8 KB of kernel memory on 32-bit architectures.
