These are called "virtual" because you 129 can run several virtual terminals (also called virtual consoles) on 130 one physical terminal. This is rather useful, for example one 131 virtual terminal can collect system messages and warnings, another 132 one can be used for a text-mode user session, and a third could run 133 an X session, all in parallel. Switching between virtual terminals 134 is done with certain key combinations, usually Alt-<function key>. 135 136 The setterm command ("man setterm") can be used to change the 137 properties (such as colors or beeping) of a virtual terminal. The 138 man page console_codes(4) ("man console_codes") contains the special 139 character sequences that can be used to change those properties 140 directly. The fonts used on virtual terminals can be changed with 141 the setfont ("man setfont") command and the key bindings are defined 142 with the loadkeys ("man loadkeys") command. 143 144 You need at least one virtual terminal device in order to make use 145 of your keyboard and monitor. Therefore, only people configuring an 146 embedded system would want to say N here in order to save some 147 memory; the only way to log into such a system is then via a serial 148 or network connection. 149 150 If unsure, say Y, or else you won't be able to do much with your new 151 shiny Linux system :-) 152 153config VT_CONSOLE 154 bool "Support for console on virtual terminal" 155 depends on VT 156 ---help--- 157 The system console is the device which receives all kernel messages 158 and warnings and which allows logins in single user mode. If you 159 answer Y here, a virtual terminal (the device used to interact with 160 a physical terminal) can be used as system console. This is the most 161 common mode of operations, so you should say Y here unless you want 162 the kernel messages be output only to a serial port (in which case 163 you should say Y to "Console on serial port", below). 164 165 If you do say Y here, by default the currently visible virtual 166 terminal (/dev/tty0) will be used as system console. You can change 167 that with a kernel command line option such as "console=tty3" which 168 would use the third virtual terminal as system console. (Try "man 169 bootparam" or see the documentation of your boot loader (lilo or 170 loadlin) about how to pass options to the kernel at boot time.) 171 172 If unsure, say Y. 173 174config HW_CONSOLE 175 bool 176 depends on VT && !S390 && !UM 177 default y 178 179comment "Unix98 PTY support" 180 181config UNIX98_PTYS 182 bool "Unix98 PTY support" 183 ---help--- 184 A pseudo terminal (PTY) is a software device consisting of two 185 halves: a master and a slave. The slave device behaves identical to 186 a physical terminal; the master device is used by a process to 187 read data from and write data to the slave, thereby emulating a 188 terminal. Typical programs for the master side are telnet servers 189 and xterms. 190 191 Linux has traditionally used the BSD-like names /dev/ptyxx for 192 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme 193 has a number of problems. The GNU C library glibc 2.1 and later, 194 however, supports the Unix98 naming standard: in order to acquire a 195 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo 196 terminal is then made available to the process and the pseudo 197 terminal slave can be accessed as /dev/pts/<number>. What was 198 traditionally /dev/ttyp2 will then be /dev/pts/2, for example. 199 200 The entries in /dev/pts/ are created on the fly by a virtual 201 file system; therefore, if you say Y here you should say Y to 202 "/dev/pts file system for Unix98 PTYs" as well. 203 204 If you want to say Y here, you need to have the C library glibc 2.1 205 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). 206 Read the instructions in <file:Documentation/Changes> pertaining to 207 pseudo terminals.
