Zeek analyzers perform application layer decoding, anomaly detection, signature matching and connection analysis. [13] Zeek's developers designed the software to incorporate additional analyzers. The latest method for creating new protocol analyzers relies on the Spicy framework.
Results of these tests remain unclear, which in general describes the status of the terrestrial digital radio broadcasting effort in North America. While traditional terrestrial radio broadcasters are trying to "go digital", most major US automobile manufacturers are promoting digital satellite radio. HD Radio technology has also made inroads ...
Data Terminal Ready (DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate a communications channel.
