Devpts

Simplified structure of the Linux kernel: Terminals and character device drivers, a.k.a. the "TTY subsystem".

devpts is a virtual filesystem directory available in the Linux kernel since version 2.1.93 (April 1998). It is normally mounted at /dev/pts and contains solely devices files which represent slaves to the multiplexing master located at /dev/ptmx which in turn is used to implement terminal emulators (such as X11 xterm).[1][2]
