Colrdx is a simple client for amateur radio dx-clusters. In a split-screen display you can type commands for the cluster in the bottom part. Messages from the dx-cluster will appear in the main window. There is also a status line at the top with some basic information.

To start colrdx, open a terminal window and type the command. You must provide your callsign and the name of the packet cluster. Optionally, you may also wish to provide the port:
colrdx -c <call> <nodename> [<port>]
You will see some introductory information from the cluster and spots will begin to appear. You may type commands to the cluster (dependent on the particular cluster). To exit type quit.
There is a manpage with additional details.
