Cwirc is a plugin for the x-chat irc client to transmit raw morse code over the internet using irc servers as reflectors. the transmitted morse code can be received in near real-time by other x-chat clients with the cwirc plugin. cwirc tries to emulate a standard amateur radio rig : it sends and receives morse over virtual channels, and it can listen to multiple senders transmitting on the same channel. morse code is keyed locally using a straight or iambic key connected to a serial port, or using the mouse buttons, and the sound is played through the soundcard.
