Benefits of the software:


Sniff serial ports

Intercept and log all data exchanged between devices connected to serial ports and applications that interact with them. Once an app starts talking to a device, the app automatically detects the activity and you can start monitoring the port in a real-time mode. This helps to track possible problems immediately.

Watch several ports simultaneously

Serial port monitoring can be done for several ports at a time. Data is presented in logs on a first-in-first-out basis, which is convenient for analysis.

View data

Choose one of the following modes to view data – table, line, dump or terminal. Each of them has a unique way of presenting information – figure out which one suits you best. There are dynamic filters you can use to focus only on relevant info.

Emulate data sent to devices

To check how monitored devices respond to a specific type of data, you can emulate data sent to devices. This can be binary, octal, decimal or any other kind of data. Switch to Terminal mode of the Serial Port Monitor to make use of this feature.
