This package provides callaudiod, a daemon to route audio during phone calls, and a library.

GNU oSIP is an implementation of the SIP protocol. It is used to provide multimedia and telecom software developers with an interface to initiate and control SIP sessions.

Seren is a simple VoIP program based on the Opus codec that allows you to create a voice conference from the terminal, with up to 10 participants, without having to register accounts, exchange emails, or add people to contact lists. All you need to join an existing conference is the host name or IP address of one of the participants.

mlterm is a multi-lingual terminal emulator. It supports various complex character sets and encodings from around the world. It can display double-width (e.g. East Asian) glyphs, combining characters used for, e.g., Thai and Vietnamese, and bi-directional scripts like Arabic and Hebrew.

This package provides a thin wrapper for fzf.

Kmscon is a terminal emulator based on Linux's KMS. It can replace the in-kernel VT implementation with a user-space console. Compared to the Linux console, kmscon provides enhanced features including XKB-compatible internationalized keyboard support, UTF-8 input/font support, hardware-accelerated rendering, multi-seat support, a replacement for mingetty, and more.

FbTerm is a fast terminal emulator for Linux with frame buffer device or VESA video card. Features include:

• mostly as fast as terminal of Linux kernel while accelerated scrolling is enabled;

• select font with fontconfig and draw text with freetype2, same as Qt/Gtk+ based GUI apps;

• dynamically create/destroy up to 10 windows initially running default shell;

• record scrollback history for every window;

• auto-detect current locale and convert text encoding, support double width scripts like Chinese, Japanese etc;

• switch between configurable additional text encodings with hot keys on the fly;

• copy/paste selected text between windows with mouse when gpm server is running;

• change the orientation of screen display, a.k.a. screen rotation;

• lightweight input method framework with client-server architecture;

• background image for eye candy.

This package provides an interactive command-line filter usable with any list--including files, command history, processes and more.

TSM is a state machine for DEC VT100-VT520 compatible terminal emulators. It tries to support all common standards while keeping compatibility to existing emulators like xterm, gnome-terminal, konsole, among others.

Bootterm is a terminal designed to ease connection to ephemeral serial ports. It features automatic port detection, port enumeration, support for non-standard baud rates, the ability to wait for ports to appear, and the ability to read and write via stdin and stdout.

Use asciinema to record and share your terminal sessions, the right way. Forget screen recording apps and blurry video. Enjoy a lightweight, purely text-based approach to terminal recording.

Alacritty is a GPU-accelerated terminal emulator with a strong focus on simplicity and performance. With such a strong focus on performance, included features are carefully considered and you can always expect Alacritty to be blazingly fast. By making sane choices for defaults, Alacritty requires no additional setup. However, it does allow configuration of many aspects of the terminal. Note that you need support for OpenGL 3.2 or higher.

tio is a simple TTY terminal application which features a straightforward commandline interface to easily connect to TTY devices for basic input/output.

tmate is a terminal sharing application that allows you to share your terminal with other users over the Internet. tmate is a fork of tmux.

Libptytty is a small C/C++ library to manage pseudo-ttys in a uniform way, created out of frustration over the many differences of PTY/TTY handling in different operating systems.

In addition to mere PTY/TTY management, it supports updating the session database at utmp, and wtmp/lastlog for login shells.

It also supports forking after start-up and dropping privileges in the calling process. This reduces the potential attack surface: if the calling process were to be compromised by the user starting the program, there would be less to gain, as only the helper process is running with privileges (e.g., setuid/setgid).

Kmscon is a terminal emulator based on Linux's KMS. It can replace the in-kernel VT implementation with a user-space console. Compared to the Linux console, kmscon provides enhanced features including XKB-compatible internationalized keyboard support, UTF-8 input/font support, hardware-accelerated rendering, multi-seat support, a replacement for mingetty, and more.

Havoc is a minimal terminal emulator for Wayland.

Unibilium is a basic C terminfo library. It doesn't depend on curses or any other library. It also doesn't use global variables, so it should be thread-safe.
