NAME

pty - pseudo terminal driver

SYNOPSIS

pseudo-device pty

DESCRIPTION

The pty driver supports a device-pair called pseudoterminal. A pseudo terminal is a pair of character devices, a master device and a slave device.  The slave device provides interface processes identical to those described in tty(4). Unlike the other devices of tty, the slave device is manipulated by the pseudo terminal’s master half.  As a result, anything written on the master device is passed as input to the slave device and vice versa. 

The command make_devices in the EXOS installation procedures creates four pairs of devices.
