Any text typed while in the conference is sent to all the parties involved. A header before the text shows its origin. The header is not repeated if the next text has the same origin. In the conference, the commands should begin with a semi-colon in the first column, so as to be interpreted as commands and not text. Commands in the Conference mode: .C[PORT] CALLSIGN : Connect to a callsign on a port. The port indication is optional; the port of the connected user is otherwise chosen as a default. .D CALLSIGN : Disconnects the callsign from the conference. .H : Help .W : Shows a list of the participants in the conference. .Q : Exit the conference.
