88 default y
89 ---help---
90 If you say Y here, you will get support for terminal devices with
91 display and keyboard devices. These are called "virtual" because you
92 can run several virtual terminals (also called virtual consoles) on
93 one physical terminal. This is rather useful, for example one
94 virtual terminal can collect system messages and warnings, another
95 one can be used for a text-mode user session, and a third could run
96 an X session, all in parallel. Switching between virtual terminals
97 is done with certain key combinations, usually Alt-<function key>.
98
99 The setterm command ("man setterm") can be used to change the
100 properties (such as colors or beeping) of a virtual terminal. The
101 man page console_codes(4) ("man console_codes") contains the special
102 character sequences that can be used to change those properties
103 directly. The fonts used on virtual terminals can be changed with
104 the setfont ("man setfont") command and the key bindings are defined
105 with the loadkeys ("man loadkeys") command.
106
107 You need at least one virtual terminal device in order to make use
108 of your keyboard and monitor. Therefore, only people configuring an
109 embedded system would want to say N here in order to save some
110 memory; the only way to log into such a system is then via a serial

124 a physical terminal) can be used as system console. This is the most
125 common mode of operations, so you should say Y here unless you want
126 the kernel messages be output only to a serial port (in which case
127 you should say Y to "Console on serial port", below).
128
129 If you do say Y here, by default the currently visible virtual
130 terminal (/dev/tty0) will be used as system console. You can change
131 that with a kernel command line option such as "console=tty3" which
132 would use the third virtual terminal as system console. (Try "man

567 bool "Unix98 PTY support"
568 ---help---
569 A pseudo terminal (PTY) is a software device consisting of two
570 halves: a master and a slave. The slave device behaves identical to
571 a physical terminal; the master device is used by a process to
572 read data from and write data to the slave, thereby emulating a
573 terminal. Typical programs for the master side are telnet servers
574 and xterms.
575
576 Linux has traditionally used the BSD-like names /dev/ptyxx for
577 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
578 has a number of problems. The GNU C library glibc 2.1 and later,
579 however, supports the Unix98 naming standard: in order to acquire a
580 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
581 terminal is then made available to the process and the pseudo
582 terminal slave can be accessed as /dev/pts/<number>. What was
583 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
584
585 The entries in /dev/pts/ are created on the fly by a virtual
586 file system; therefore, if you say Y here you should say Y to
587 "/dev/pts file system for Unix98 PTYs" as well.
588
589 If you want to say Y here, you need to have the C library glibc 2.1
590 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
591 Read the instructions in <file:Documentation/Changes> pertaining to
592 pseudo terminals. It's safe to say N.

601 machines which support incoming telnet/rlogin/ssh connections and/or
602 serve several X terminals may want to increase this: every incoming
603 connection and every xterm uses up one PTY.
