Docklight is a testing, analysis and simulation tool for serial communication protocols (RS232, RS485/422 and others). It allows you to monitor the communication between two serial devices or to test the serial communication of a single device.
Docklight is easy to use and runs on almost any standard PC using Windows 7, Windows Vista, Windows XP or Windows 2000/NT 4 operating system.
Docklight can send out user-defined sequences according to the protocol used and it can react to incoming sequences. This makes it possible to simulate the behavior of a serial communication device, which is particularly useful for generating test conditions that are hard to reproduce with the original device.
This app allows you to check the flow of data through a computer's COM ports.
