These are called "virtual" because you 126 can run several virtual terminals (also called virtual consoles) on 127 one physical terminal. This is rather useful, for example one 128 virtual terminal can collect system messages and warnings, another 129 one can be used for a text-mode user session, and a third could run 130 an X session, all in parallel. Switching between virtual terminals 131 is done with certain key combinations, usually Alt-<function key>. 132 133 The setterm command ("man setterm") can be used to change the 134 properties (such as colors or beeping) of a virtual terminal. The 135 man page console_codes(4) ("man console_codes") contains the special 136 character sequences that can be used to change those properties 137 directly. The fonts used on virtual terminals can be changed with 138 the setfont ("man setfont") command and the key bindings are defined 139 with the loadkeys ("man loadkeys") command. 140 141 You need at least one virtual terminal device in order to make use 142 of your keyboard and monitor. Therefore, only people configuring an 143 embedded system would want to say N here in order to save some 144 memory; the only way to log into such a system is then via a serial 145 or network connection. 146 147 If unsure, say Y, or else you won't be able to do much with your new 148 shiny Linux system :-) 149 150config VT_CONSOLE 151 bool "Support for console on virtual terminal" 152 depends on VT 153 ---help--- 154 The system console is the device which receives all kernel messages 155 and warnings and which allows logins in single user mode. If you 156 answer Y here, a virtual terminal (the device used to interact with 157 a physical terminal) can be used as system console. This is the most 158 common mode of operations, so you should say Y here unless you want 159 the kernel messages be output only to a serial port (in which case 160 you should say Y to "Console on serial port", below). 161 162 If you do say Y here, by default the currently visible virtual 163 terminal (/dev/tty0) will be used as system console. You can change 164 that with a kernel command line option such as "console=tty3" which 165 would use the third virtual terminal as system console. (Try "man 166 bootparam" or see the documentation of your boot loader (lilo or 167 loadlin) about how to pass options to the kernel at boot time.) 168 169 If unsure, say Y. 170 171config HW_CONSOLE 172 bool 173 depends on VT && !S390 && !UM 174 default y 175 176comment "Unix98 PTY support" 177 178config UNIX98_PTYS 179 bool "Unix98 PTY support" 180 ---help--- 181 A pseudo terminal (PTY) is a software device consisting of two 182 halves: a master and a slave. The slave device behaves identical to 183 a physical terminal; the master device is used by a process to 184 read data from and write data to the slave, thereby emulating a 185 terminal. Typical programs for the master side are telnet servers 186 and xterms. 187 188 Linux has traditionally used the BSD-like names /dev/ptyxx for 189 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme 190 has a number of problems. The GNU C library glibc 2.1 and later, 191 however, supports the Unix98 naming standard: in order to acquire a 192 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo 193 terminal is then made available to the process and the pseudo 194 terminal slave can be accessed as /dev/pts/<number>. What was 195 traditionally /dev/ttyp2 will then be /dev/pts/2, for example. 196 197 The entries in /dev/pts/ are created on the fly by a virtual 198 file system; therefore, if you say Y here you should say Y to 199 "/dev/pts file system for Unix98 PTYs" as well. 200 201 If you want to say Y here, you need to have the C library glibc 2.1 202 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). 203 Read the instructions in <file:Documentation/Changes> pertaining to 204 pseudo terminals. It's safe to say N. 205 206config UNIX98_PTY_COUNT 207 int "Maximum number of Unix98 PTYs in use (0-2048)" 208 depends on UNIX98_PTYS 209 default "256" 210 help 211 The maximum number of Unix98 PTYs that can be used at any one time. 212 The default is 256, and should be enough for desktop systems. Server 213 machines which support incoming telnet/rlogin/ssh connections and/or 214 serve several X terminals may want to increase this: every incoming 215 connection and every xterm uses up one PTY. 216 217 When not in use, each additional set of 256 PTYs occupy 218 approximately 8 KB of kernel memory on 32-bit architectures. 219 220source "drivers/char/pcmcia/Kconfig" 221 222source "drivers/serial/Kconfig" 223 224source "drivers/i2c/Kconfig" 225 226source "drivers/hwmon/Kconfig" 227 228source "drivers/usb/Kconfig" 229 230endmenu 231 232source "fs/Kconfig" 233 234source "arch/h8300/Kconfig.debug" 235 236source "security/Kconfig" 237 238source "crypto/Kconfig" 239 240source "lib/Kconfig" 241
