A combination terminal/sniffer: Imagine a terminal emulation program, like HyperTerminal or a telnet client. Allow it to send and receive arbitrary binary data in HEX or TEXT form. Pour in ultimate I/O flexibility, allowing it to work with any underlying transport, be it a serial port, TCP/UDP in client or server modes, named pipe or anything else. Add the monitoring capabilities of a network sniffer or a serial monitor. Now sprinkle a dash of style and common sense, and you`ve got an elegant and powerful tool for debugging almost any communication scenario you can throw at it. Create a TCP/UDP/PIPE connection using the Connection Socket plugin. Listen to an incoming TCP/UDP/PIPE connection using the Listener Socket plugin. Monitor Ethernet traffic using the Network Sniffer plugin. Send/receive UDP traffic and perform connectionless UDP operations using the UDP Socket plugin. Act as a proxy and monitor all traffic being passed, for scenarios where a network sniffer just won`t cut it. Create a serial connection using the Serial Connection plug-in. Inspect and analyze a program`s debug trace, to track down the cause for software crashes. Do it all using a streamlined, well thought-out interface.
