The slave device behaves identical to + a physical terminal; the master device is used by a process to + read data from and write data to the slave, thereby emulating a + terminal. Typical programs for the master side are telnet servers + and xterms. + + Linux has traditionally used the BSD-like names /dev/ptyxx for + masters and /dev/ttyxx for slaves of pseudo terminals. This scheme + has a number of problems. The GNU C library glibc 2.1 and later, + however, supports the Unix98 naming standard: in order to acquire a + pseudo terminal, a process opens /dev/ptmx; the number of the pseudo + terminal is then made available to the process and the pseudo + terminal slave can be accessed as /dev/pts/<number>. What was + traditionally /dev/ttyp2 will then be /dev/pts/2, for example. + + The entries in /dev/pts/ are created on the fly by a virtual + file system; therefore, if you say Y here you should say Y to + "/dev/pts file system for Unix98 PTYs" as well. + + If you want to say Y here, you need to have the C library glibc 2.1 + or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*"). + Read the instructions in <file:Documentation/Changes> pertaining to + pseudo terminals.
