DCOP (desktop communication protocol) was KDE's means of communicating between processes during the KDE 3 series. In order to facilitate more collaboration with other Free Software desktop projects, the version 4 series switched to D-Bus which then even got support in Qt4 itself. There are several D-Bus command line tools available, e.g. dbus-send (from the core D-Bus package) or qdbus (from Qt, package "qdbus"). The latter has a similar behavior like the dcop command line tool, e.g. invoking it without any argument shows the known D-Bus connections (programs using D-Bus) and so on. There is also an UI tool calls qdbusviewer, package qt4-dev-tools, which makes exploring available interfaces easier than repeatedly calling the commandline tool.
