List of the best RS232 Sniffers

The RS232 communication protocol is used in a wide variety of scientific applications that employ peripheral devices to control and measure various physical aspects of a process or phenomena. These devices use serial ports, and it can be difficult to effectively monitor activity flowing through these interfaces. Analyzing data transmission and addressing problems with serial data requires a robust serial port monitor that can log a system’s RS232 activity.

Many different solutions are available that can perform COM port monitoring to better understand how your connected devices are operating. This article will show you several products that can efficiently monitor and analyze the activity of your system’s serial ports.

HDD Serial Port Monitor

HDD Serial Port Monitor is another friendly COM port sniffer for Windows, which allows monitoring and recording data from RS-232, RS-422, and RS-485 interfaces. This handy solution will help you easily analyze serial port activity and detect any issues with serial data communications.

Serial Port Monitor freeware gives you the way to sniff several COM ports simultaneously, so you can see how your apps interact with several serial devices within one session.

This app is especially useful for those who develop serial software, device drivers or serial hardware. It is a convenient tool for testing, debugging, and optimizing RS232 products.

One of the key advantages of this solution is that you can use this software sniffer of RS232 ports for free, but with limitation.

Serial Monitor is a reliable solution which works with high data transfer rates and makes it possible to easily change the way the raw data is displayed. Even if the session is completed you can still save the monitored data for its further analysis. This RS232 serial communication software is friendly and flexible and definitely deserves your attention if you’re a serial app developer or tester.

Serial Port Sniffer by AGG Software

Serial Port Sniffer by AGG Software can monitor all traffic sent and received by a particular serial port. What’s especially convenient is that the data sent can be highlighted in the software window.

This serial port sniffer will also display the transferred data in any format (hexadecimal, decimal, or any other). This way you can identify the repeated sequence of data blocks without closing the monitoring app.

Compared to most other com port sniffers, Serial Port Monitor by AGG Software has several major advantages:

• The software is able to work across a wide range of Windows platforms, starting with Windows 2000 and ending with Windows 10 (x64);
• With this program, you can monitor the transmission of data via all serial ports available in your system. You can sniff from 1 to 255 ports;
• Serial Port Monitor allows you to capture the traffic transmitted during a dial-up connection, and more.

RS232 Sniffer Hardware Solution. Hardware serial port sniffer tools

1. Avisaro RS232 «Sniffer» Interface

Logging of serial port data is no longer a problem for those who use RS232 bidirectional data sniffing interface provided by Avisaro.

The compact hardware unit is designed to record data communicated between two devices over the RS232 protocol. Together with the Avisaro Data Logger app, this sniffer box is used to capture data transmitted in both the Rx and Tx directions and store it in a table format. That means you can use Excel or any text editor to read your serial data.

RS232 «Sniffer» Interface is widely applied for RS232 communication debugging and re-engineering of data protocols.

2. EZ-Tap RS232 Pro RS232 sniffer

RS232 hardware sniffer produced by Stratus Engineering will help you resolve the latency and time-tagging issues commonly faced by users of traditional dual COM port sniffing tools.

The clear benefits you get with EZ-Tap RS232 Pro hardware:

• No need to rely on bulky and expansive RS232 sniffer cables;
• You can track down the activity of multiple serial interfaces at a time and redirect the monitoring data to a file;
• The app provides simple access to serial ports and logging of all the data sent and received;
• EZ-Tap RS232 Pro fully supports Windows 2000/XP/Vista/7/10 (x32 and x64);
• Together with the hardware Com Port Sniffer, you receive the device drivers, Mini-B USB cable and a dedicated EZ-View monitoring software.

This RS232 packet analyzer can monitor full and half duplex serial communications and stream data to a dedicated RS232CPM COM monitor application.As well as an active rs232 sniffer cable that monitors the DTE/DCE and RTS/CTS lines in addition and Tx/Rx lines. EZ-Tap RS232 Pro is equipped with a male DB9 connector on one end and a female DB9 connector on the other end. Thanks to this, it can be inserted between two COM-based devices that need to be sniffed.

To use this solution, you just need to connect it to a USB port of your PC with the help of a USB A to mini B cable, install its drivers as well as the supplied RS232CPM app and start sniffing.

A nice thing about the RS232 COM Tap is that it can also be used with any RS232 terminal app supporting virtual COM ports, for instance, Windows HyperTerminal.

3. Serial Tap by Tibbo

The Hardware Serial Tap is a simple yet efficient sniffer tailored for monitoring of RS232, RS485, and TTL-level UART communications. This sniffer board is natively supported via the Serial Tap plugin.

Here’s how the solution works:

• You connect your Serial Tap hardware over a USB cable and select it in the Serial Tap plugin.
• Next, you specify the baud rate at which the serial communication you are going to sniff works.
• Then, you click Capture and get the communication data displayed. In addition to serial data, you’ll see all control line changes and status line changes. This is it.

Modbus Sniffer

Modbus is a master/slave serial communication protocol popular in the industrial environment mainly because it’s openly published and royalty-free. Originally It was used to connect various industrial electronic devices over RS-485 protocol, though many other versions are available now for RS-232, RS-422, and TCP/IP (Modbus TCP) protocols.

Modbus protocol has a broad scope of application, particularly Modbus ASCII and Modbus RTU versions. The second is used the most among all Modbus protocols. So, if you are in the process of developing software to communicate with some electronic devices through the Modbus RTU, you’re definitely going to need a high- grade Modbus RTU sniffer. It’s a specialized RS485 Protocol Analyzer that will help you to analyze data sent through the protocol. The same applies to the Modbus ASCII version, with the only difference that you’ll need another version of a port scanner software.

Modbus Sniffer by Electronic Team, Inc. allows you to not only monitor all the relevant data sent through Modbus ASCII and Modbus RTU protocols but also log it for future analysis. It has a user-friendly interface and displays data in different view modes. On top of that, this particular protocol analyzer provides an opportunity to filter collected data for more accurate analysis.

With this professional-grade Modbus sniffer software you’ll be able to:

• Establish a connection with any serial port and instantly get a full real-time view of all the information transferred through it, so you can straightaway fix all the emerging problems. Even if some other application is already using that port at the very same time, it won’t stop Modbus Sniffer to effectively carry out its task.
• Simultaneously monitor multiple serial ports and conveniently log all the gathered information into a single file by the first-in-first-out principle.
• Choose the modes to display captured data: table, line, dump or terminal. Use them in any combination and apply filters for a more accurate and comprehensive analysis.
• Check the serial device’s response to specific commands with an emulated transmission of data.
• Use the terminal mode to emulate data transmission from a monitored serial port to a device that is connected to it. This feature might be particularly useful during the Modbus communication test, given that it provides means to monitor any given device responds to certain commands or data.

Free serial port sniffers on the market

Portmon monitors Windows kernel-level I/O packets sent/received between serial port device drivers. It didn’t update for some time and may not work on modern versions of Windows.

How can our serial software replace free Portmon?

Apart from Portmon, our software does not show low-level I/O requests, but decodes them to a human-readable form.

How can our software help decode serial communication protocol?

When studying serial communication protocols, you may want to repeat the same command sequence sent to serial equipment. You can quickly switch from the sniffer mode to the manual mode, repeat RS232 communications using our «Replay logs» plugin.
