SerLooK is a KDE application for inspecting data going over serial lines. It can work as a binary terminal that sends and receives data through a defined port (Point to Point mode) and displays them on separate views. Each view can be configured to display data in hexadecimal, decimal, octal, binary, and raw ASCII. It is also possible to perform I/O through terminal emulation views and define a secondary port and monitor the traffic between two external hosts using a "Y" cable (Snooper mode).
Oculus Server Monitor uses a plain text, human readable protocol to export server information to any client that connects to it. It supports a plugin system for commands, an XML-style configuration file, and IP-based access control. Odie, the Oculus Daemon InterfeacE, is a rich Web application that polls a list of hosts for their status.
