| 111 | bool "Virtual terminal" |
| 112 | ---help--- |
| 113 | If you say Y here, you will get support for terminal devices with |
| 114 | display and keyboard devices. These are called "virtual" because you |
| 115 | can run several virtual terminals (also called virtual consoles) on |
| 116 | one physical terminal. This is rather useful, for example one |
| 117 | virtual terminal can collect system messages and warnings, another |
| 118 | one can be used for a text-mode user session, and a third could run |
| 119 | an X session, all in parallel. Switching between virtual terminals |
| 120 | is done with certain key combinations, usually Alt-<function key>. |
| 121 | |
| 122 | The setterm command ("man setterm") can be used to change the |
| 123 | properties (such as colors or beeping) of a virtual terminal. The |
| 124 | man page console_codes(4) ("man console_codes") contains the special |
| 125 | character sequences that can be used to change those properties |
| 126 | directly. The fonts used on virtual terminals can be changed with |
| 127 | the setfont ("man setfont") command and the key bindings are defined |
| 128 | with the loadkeys ("man loadkeys") command. |
| 129 | |
| 130 | You need at least one virtual terminal device in order to make use |
| 131 | of your keyboard and monitor. Therefore, only people configuring an |
| 132 | embedded system would want to say N here in order to save some |
| 133 | memory; the only way to log into such a system is then via a serial |
| 134 | or network connection. |
| 135 | |
| 136 | If unsure, say Y, or else you won't be able to do much with your new |
| 137 | shiny Linux system :-) |
| 138 | |
| 139 | config VT_CONSOLE |
| 140 | bool "Support for console on virtual terminal" |
| 141 | depends on VT |
| 142 | ---help--- |
| 143 | The system console is the device which receives all kernel messages |
| 144 | and warnings and which allows logins in single user mode. If you |
| 145 | answer Y here, a virtual terminal (the device used to interact with |
| 146 | a physical terminal) can be used as system console. This is the most |
| 147 | common mode of operations, so you should say Y here unless you want |
| 148 | the kernel messages be output only to a serial port (in which case |
| 149 | you should say Y to "Console on serial port", below). |
| 150 | |
| 151 | If you do say Y here, by default the currently visible virtual |
| 152 | terminal (/dev/tty0) will be used as system console. You can change |
| 153 | that with a kernel command line option such as "console=tty3" which |
| 154 | would use the third virtual terminal as system console. (Try "man |
| 155 | bootparam" or see the documentation of your boot loader (lilo or |
| 156 | loadlin) about how to pass options to the kernel at boot time.) |
| 157 | |
| 158 | If unsure, say Y. |

| 167 | config UNIX98_PTYS |
| 168 | bool "Unix98 PTY support" |
| 169 | ---help--- |
| 170 | A pseudo terminal (PTY) is a software device consisting of two |
| 171 | halves: a master and a slave. The slave device behaves identical to |
| 172 | a physical terminal; the master device is used by a process to |
| 173 | read data from and write data to the slave, thereby emulating a |
| 174 | terminal. Typical programs for the master side are telnet servers |
| 175 | and xterms. |
| 176 | |
| 177 | Linux has traditionally used the BSD-like names /dev/ptyxx for |
| 178 | masters and /dev/ttyxx for slaves of pseudo terminals. This scheme |
| 179 | has a number of problems. The GNU C library glibc 2.1 and later, |
| 180 | however, supports the Unix98 naming standard: in order to acquire a |
| 181 | pseudo terminal, a process opens /dev/ptmx; the number of the pseudo |
| 182 | terminal is then made available to the process and the pseudo |
| 183 | terminal slave can be accessed as /dev/pts/<number>. What was |
| 184 | traditionally /dev/ttyp2 will then be /dev/pts/2, for example. |
| 185 | |
| 186 | The entries in /dev/pts/ are created on the fly by a virtual |
| 187 | file system; therefore, if you say Y here you should say Y to |
| 188 | "/dev/pts file system for Unix98 PTYs" as well. |
| 189 | |
| 190 | If you want to say Y here, you need to have the C library glibc 2.1 |
| 191 | or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). |
| 192 | Read the instructions in <file:Documentation/Changes> pertaining to |
| 193 | pseudo terminals. It's safe to say N. |
| 194 | |
| 195 | config UNIX98_PTY_COUNT |
| 196 | int "Maximum number of Unix98 PTYs in use (0-2048)" |
| 197 | depends on UNIX98_PTYS |
| 198 | default "256" |
| 199 | help |
| 200 | The maximum number of Unix98 PTYs that can be used at any one time. |
| 201 | The default is 256, and should be enough for desktop systems. Server |
| 202 | machines which support incoming telnet/rlogin/ssh connections and/or |
| 203 | serve several X terminals may want to increase this: every incoming |
| 204 | connection and every xterm uses up one PTY. |
| 205 | |
| 206 | When not in use, each additional set of 256 PTYs occupy |
| 207 | approximately 8 KB of kernel memory on 32-bit architectures. |
