232Analyzer allows you to analyze the communication and other activities that are happening through serial ports. This powerful application also allows controlling and monitoring serial ports, not only analyzing their parameters. These serial ports can be of various types, such as the ubiquitous RS232 (hence the name of the application), but it will also let you control, monitor and analyze the rarer used RS485, RS422 or TTL protocols thanks to the built-in converters.

I appreciate a lot the many features, functions and options that this application provides. For example, it lets you input and monitor data in multiple formats, such as ASCII, hexadecimal, decimal, octal and binary. Monitoring and logging handshaking signal flows of many kinds (CTS, RTS, DTR, DSR, DCD, and RI) are also possible. This data can be logged and saved to text files of various types, such as RTF, TXT or even DOC files. Automatic COM port number detection is also supported, as well as debugging and terminal emulation functions.

Despite the fact that it offers a lot of features, this program comes with a simple and neat interface. Most serial port analyzers are terribly intricate and force their users to waste time just to get used to them, but that's not the case with 232Analyzer. This application is intuitive and straightforward.

In conclusion, 232Analyzer is exactly how any serial port analyzing application should be: comprehensive and feature-rich enough to satisfy any potential serial port analyzing needs but also straightforward and untroublesome.
