Common scenarios when it's required to test serial port and monitor serial communication:

Monitor and logs asynchronous serial transmission can help in the improvement of downtime and condition

There may be the need to analyze and record data from peripherals such as card reader, printers, keyboards, mice and terminals to determine the reason for a problem

There may be a need to provide find data exchange protocols for one machine without a document left

There may be a need to monitor and backup sensitive data from devices like card readers, barcode scanners, and point-of-sale

There may be a need to monitor and log data from sensors: voltage, pressure, temperature, etc.

Why do you need Serial Port Tester software?

Serial Port Tester makes it possible to track the activity of RS232/422/485 ports in real time. It's ideal for those debug and develop firmware, as well as those who proffer hardware and software serial port solutions.
