Serialport Utility

Practical serial port testing and logging

Serialport Utility is a Windows tool built for people who need to send, receive, inspect, and record data through COM ports. It is aimed mainly at developers, hardware testers, and technical users working with serial-connected equipment such as GPS devices, relay boards, medical instruments, DMX devices, Electronic Total Stations, and ZigBee or Xbee-based hardware.

The program’s main strength is that it brings several serial communication tasks into one workspace. It can detect available COM-connected devices automatically and present them in a selectable list, which makes setup easier for users who do not want to manually hunt through port names. Once connected, it can send and receive data, display information as text, hexadecimal, or decimal values, and help users inspect what is happening on the port in real time.

Serialport Utility is especially useful during debugging and testing. Its dual-panel layout helps separate sent and received information, while logging tools let users track activity for later review. Data can be redirected to a file or copied out for documentation. The included checksum calculator is also helpful when checking whether transmitted data is structured correctly. For more advanced workflows, the software supports TCP and UDP communication, including server and client functions, as well as sending commands and files through the selected port.

Everyday usability is practical rather than flashy. Users who understand serial communication will likely appreciate the clear access to port settings, loop intervals, data bits, flow options, and display controls. Less experienced users can still use the basics, but some knowledge of COM ports and device protocols will make the software far more useful.

There are some limits. The controller database is not as frequently updated as it could be, profile management is limited, and users looking for deep keyboard or mouse emulation may find the options modest. Fine-tuning controls are also not exhaustive.

Overall, Serialport Utility is best suited to developers, testers, technicians, and hardware hobbyists who need a dependable way to monitor, send, log, and analyze serial data on Windows.
