113 | config VT | |
114 | bool "Virtual terminal" | |
115 | ---help--- | |
116 | If you say Y here, you will get support for terminal devices with | |
117 | display and keyboard devices. These are called "virtual" because you | |
118 | can run several virtual terminals (also called virtual consoles) on | |
119 | one physical terminal. This is rather useful, for example one | |
120 | virtual terminal can collect system messages and warnings, another | |
121 | one can be used for a text-mode user session, and a third could run | |
122 | an X session, all in parallel. Switching between virtual terminals | |
123 | is done with certain key combinations, usually Alt-<function key>. | |
124 | ||
125 | The setterm command ("man setterm") can be used to change the | |
126 | properties (such as colors or beeping) of a virtual terminal. The | |
127 | man page console_codes(4) ("man console_codes") contains the special | |
128 | character sequences that can be used to change those properties | |
129 | directly. The fonts used on virtual terminals can be changed with | |
130 | the setfont ("man setfont") command and the key bindings are defined | |
131 | with the loadkeys ("man loadkeys") command. | |
132 | ||
133 | You need at least one virtual terminal device in order to make use | |
134 | of your keyboard and monitor. Therefore, only people configuring an | |
135 | embedded system would want to say N here in order to save some | |
136 | memory; the only way to log into such a system is then via a serial | |
137 | or network connection. | |
138 | ||
139 | If unsure, say Y, or else you won't be able to do much with your new | |
140 | shiny Linux system :-) | |

142 | config VT_CONSOLE | |
143 | bool "Support for console on virtual terminal" | |
144 | depends on VT | |
145 | ---help--- | |
146 | The system console is the device which receives all kernel messages | |
147 | and warnings and which allows logins in single user mode. If you | |
148 | answer Y here, a virtual terminal (the device used to interact with | |
149 | a physical terminal) can be used as system console. This is the most | |
150 | common mode of operations, so you should say Y here unless you want | |
151 | the kernel messages be output only to a serial port (in which case | |
152 | you should say Y to "Console on serial port", below). | |
153 | ||
154 | If you do say Y here, by default the currently visible virtual | |
155 | terminal (/dev/tty0) will be used as system console. You can change | |
156 | that with a kernel command line option such as "console=tty3" which | |
157 | would use the third virtual terminal as system console. (Try "man | |
158 | bootparam" or see the documentation of your boot loader (lilo or | |
159 | loadlin) about how to pass options to the kernel at boot time.) | |
160 | ||
161 | If unsure, say Y. | |

170 | config UNIX98_PTYS | |
171 | bool "Unix98 PTY support" | |
172 | ---help--- | |
173 | A pseudo terminal (PTY) is a software device consisting of two | |
174 | halves: a master and a slave. The slave device behaves identical to | |
175 | a physical terminal; the master device is used by a process to | |
176 | read data from and write data to the slave, thereby emulating a | |
177 | terminal. Typical programs for the master side are telnet servers | |
178 | and xterms. | |
179 | ||
180 | Linux has traditionally used the BSD-like names /dev/ptyxx for | |
181 | masters and /dev/ttyxx for slaves of pseudo terminals. This scheme | |
182 | has a number of problems. The GNU C library glibc 2.1 and later, | |
183 | however, supports the Unix98 naming standard: in order to acquire a | |
184 | pseudo terminal, a process opens /dev/ptmx; the number of the pseudo | |
185 | terminal is then made available to the process and the pseudo | |
186 | terminal slave can be accessed as /dev/pts/<number>. What was | |
187 | traditionally /dev/ttyp2 will then be /dev/pts/2, for example. | |
188 | ||
189 | The entries in /dev/pts/ are created on the fly by a virtual | |
190 | file system; therefore, if you say Y here you should say Y to | |
191 | "/dev/pts file system for Unix98 PTYs" as well. | |
192 | ||
193 | If you want to say Y here, you need to have the C library glibc 2.1 | |
194 | or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). | |
195 | Read the instructions in <file:Documentation/Changes> pertaining to | |
196 | pseudo terminals. It's safe to say N. | |
197 | ||
198 | config UNIX98_PTY_COUNT | |
199 | int "Maximum number of Unix98 PTYs in use (0-2048)" | |
200 | depends on UNIX98_PTYS | |
201 | default "256" | |
202 | help | |
203 | The maximum number of Unix98 PTYs that can be used at any one time. | |
204 | The default is 256, and should be enough for desktop systems. Server | |
205 | machines which support incoming telnet/rlogin/ssh connections and/or | |
206 | serve several X terminals may want to increase this: every incoming | |
207 | connection and every xterm uses up one PTY. | |
208 | ||
209 | When not in use, each additional set of 256 PTYs occupy | |
210 | approximately 8 KB of kernel memory on 32-bit architectures. | |
