How Free Serial Analyzer Works

Program installs filter driver on top of a serial device driver. Filter driver then intercepts I/O requests issued by an application communicating with a serial device. All control requests (requests that configure port parameters) and data transfer requests (requests that pass data between app and RS-232/RS-422/RS-485 hardware device) are monitored. Each serial data request is then parsed and displayed in an easy-to-understand form using several different views.

This freeware serial snooper even allows you to trace serial data transferred between applications and devices connected to the remote PC (Device Monitoring Studio Server, network or Internet connection to the remote computer is required then).

List of the best RS232 port Loggers

Today, computer viruses have literally flooded the world and continue moving freely around the Internet. Now, when we hear the word “port”, the first thing that comes to our minds is logical ports that are used in network technologies like TCP/IPor UDP to organize communication channels, but we forget about physical ports serving for connecting external devices. High-speed USB interfaces are now seen as a universal means for connecting printers, mice and keyboards, whereas good old COM ports are used less frequently. However, the latter ones are still present in some modern computers, and probably the time has come to use them for some other purposes, for example, for controlling specialized COM-based equipment.

In order to monitor and analyze serial communications between a computer and a COM port device, you can rely on a dedicated software — serial data logger which will read and record RS232 data to a text file for its further analysis.

There are also special hardware RS232 port analyzers designed to capture analog and digital signals but, like any professional equipment, they are rather expensive to buy.

In this article, I’ll cover both software and hardware COM port loggers and highlight the clear benefits you get with one or another solution. Read on to learn how to capture serial port data to file in the fastest and simplest way.

Arduino serial data logger

Want to find out how to build an Arduino data logger and watch data from an Arduino? Here’s a quick way to do this:

If you can use an SD card in your project, that is an obvious solution to create an Arduino SD card data logger. Some Ethernet shields are provided with an SD Card reader. Or you can add an SD card by using a microSD adapter.

It won’t be difficult to interact with your SD card from an Arduino, as SD cards use a form of the SPI protocol. You only need to make sure it is a slower class. A proven way is to use Class 4 cards and make sure then are 16GB or less.

The IDE comes with an SD Example called “Datalogger”, so you can find a code example there.

Serial Port Spy — Serial port spy from our Advanced Serial Port Monitor. How serial port spy is done

For Windows 2000 — Windows 11 (2019) (incl. Server, x86 and x64) . Latest version: 4.4.21 build 527. May 27, 2022 .
