- COM Port Stress Test
- License: Freeware

When creating an application that actively communicates with external devices through COM or RS232 ports, the developer must make sure that the ports will be able to handle any data flow without producing errors and locking up the system. This becomes especially important when it comes to surveillance and alarm systems, industrial controllers, medical solutions and other areas of application where data integrity and system stability are crucial factors. If you are puzzled by having to stress-test COM/RS232 ports and see no easy way to do that, make sure you don't miss COM Port Stress Test, as it does exactly what you need! COM Port Stress Test is a compact and affordable tool for testing COM, RS232 and RS485 (with converter) ports that generates a stream of data with random communication settings.
