Pseudoterminal

In some operating systems, including Unix, a pseudoterminal, pseudotty, or PTY is a pair of pseudo-devices, one of which, the slave, emulates a hardware text terminal device, the other of which, the master, provides the means by which a terminal emulator process controls the slave. The PTY feature is part of POSIX and the Single Unix Specification in the form of a posix_openpt function since 1998.
