About

Serial Port Monitor is a professional software application that allows reading and recording serial data going through your computer’s serial ports. The program is a big help for those who develop and debug software and hardware solutions that use COM ports for serial data transfer. RS232 Port Monitor comes with a slew of powerful features, including advanced filtering and search options, built-in terminal, convenient data visualizers, the ability to record serial communication data to a file, and more. The software has a streamlined and user-friendly interface and doesn’t require any programming skills. There are Professional and Company editions of Serial Port Monitor. When using the software in terminal mode, you can emulate sending some special commands to the monitored port as though they were sent from a monitored application. This way you get the ability to check the reaction of the COM port and device connected to it.

About

SerialTool is a professional Serial Port Software to quickly and easily communicate with your PC Serial Port. SerialTool is the result of years of development and implementation of functionalities in the use of the COM port. Many features have been designed to facilitate embedded development using the COM (UART) port. Among the various functions it is possible to save buffers, insert alarms when a specific buffer arrives, save serial traffic and much more. A super easy tool for Arduino hobbyists to test their application with AutoAnswer functions. Ideal for professional users with logging functions and timed multiple packet send for intensive application stress tests. SerialTool is available for Windows, Mac OS and Linux.

Pros & Cons from Real Users

Pros

  • Excellent visibility into serial port communications and data traffic. Very useful for debugging Arduino, embedded systems, and USB-to-serial devices. Helps quickly identify baud rate, data formatting, and communication issues.
  • Serial Port Monitor is a highly convenient and effective tool that delivers exactly what it promises. It’s easy to use, even for those without deep programming knowledge, yet powerful enough for professional workflows. The ability to read, record, and analyze serial data in real time is extremely valuable, especially for debugging and development tasks involving COM ports. The built-in terminal and data visualization features stand out, making it simple to interpret communication streams without needing additional tools. Advanced filtering and search options also save a lot of time when working with large volumes of data. Overall, it offers great value for money, particularly considering the breadth of features included.
  • Although I don't have much experience with similar software, I was impressed by Serial Port Monitor right after launching it for the first time. I found the controls intuitive and was immediately able to monitor communication between the computer and BMS.
  • Top software, very easy to use and offers tons of possibilities. I stumbled upon this program by chance and I'm totally thrilled.
  • Effective debugging tool for serial communication with Arduino boards, GPS modules, USB-to-serial adapters, and other DIY hardware. Real-time data monitoring helps spot issues like mismatched baud rates, protocol errors, and unexpected device behavior. Useful for firmware testing, allowing verification of expected data during uploads and troubleshooting firmware/configuration issues. Logging functionality lets you capture serial traffic for later review, making it easier to analyze long test sessions and identify patterns. Educational value, helping you better understand serial protocols, message structures, timing, and device handshakes through hands-on observation. Great for learning and experimenting, including reverse-engineering communication on vintage or hobby devices.

Cons

  • No significant issues encountered during my use. The interface feels somewhat dated, but functionality remains excellent.
  • While the functionality is strong, the design and user interface could benefit from modernization. Compared to current software standards, some elements feel slightly outdated. Improving the visual appeal and user experience would make the tool even more attractive, especially for new users who expect more polished interfaces today.
  • I haven't found any downsides to Serial Port Monitor. Maybe the price, but that's relative, because the pros clearly outweigh the cons.
  • Unfortunately, the software is a bit expensive, but I'm considering spending the money on it anyway.
  • Focused use case — primarily valuable for those working with serial devices and microcontrollers, not general-purpose debugging.

Pros & Cons from Real Users

Pros

  • It provides lots of funny and also professional functions like the oscilloscope, modbus client, hex dataset set, send serial packets to the network and much more! For Mac users this is quite unique.
  • This software is really one of the few software with super great features which allows you to do almost whatever you want with it. Beautifully working on Linux and Windows.
  • One of the few MacOS Softwares. Save serial traffic to file. Alarm triggering on specific buffer. Send HEX and ASCII Bytes. Multiple Templates, I love the white one by the way.

Cons

  • Some flaws due to its youth but updates are quite regular.
  • There ain't many flaws or missing stuff from this software. I might say that the User Interface might be a little bit more intuitive but it is still very usable!
  • No Menu bar shortcuts. It takes a while to understand the multiple serial concept.
