COM Port Stress Test 1.4.3 Build 907

An efficient COM/RS232 stress-testing tool for software/hardware developers
COM Port Stress Test is a tool for testing a COM or RS232 port (device), that generates a serial stream of data with random communication settings.

Stress test put a greater emphasis on robustness and error handling under a heavy load, than on what would be considered correct behavior under normal circumstances in your application. The goals of such tests may be to ensure the application doesn't crash in conditions of random data flow.

COM Port Stress Test may help developers or experts test their hardware, software and applications with extreme conditions. This program can generate a very fast data flow, randomly change baudrate, flow control or RTS and DTR state.

COM Port Stress Test will allow you to you easily create a load on a serial port you want to test by simulating the activity of a serial port software.

Main features:

  • supports COM, RS232, RS485 (with converter) ports;
  • supports virtual serial port, usb serial ports;
  • can test two ports at the same time;
  • can read/write a data stream from/to a COM port;
  • can change communication parameters randomly;
  • can change RTS or DTR randomly;
  • configurable a write buffer size;
  • configurable a load value;
  • displays in/out speed and byes count.
