That behaves exactly like a classical terminal.Ī process that expects to be connected to a terminal, can open the slave end of a pseudoterminal and then be driven by a program that has

The slave end of the pseudoterminal provides an interface One end of the channel is called the master the other end is called the slave. A pseudoterminal (sometimes abbreviated "pty") is a pair of virtual character devices that provide a bidirectional communication channel. Unix/Linux had taken second approach, and provides multiple ways to create these pseudo devices, man page of pseudo terminals explains this very well ( man pty).

In this post I would like to narrate my experiences with these devices.ĭuring the initial days of computers, Serial is the most common interface Hence many of the Linux utilities are developed to work with serial devices With time as the speed of devices improved and new interfaces came to lime light, programmers are faced with a tricky situation Either modify all the programs that work with serial devices or create a pseudo interface that behaves like serial interface for these programs. People working on embedded systems might be quite familiar with serial interface, Serial is one of the most common ways to interface with an device.
