COM Port Data Emulator - Version 2.5.0.16 If you are a software developer or a hardware engineer, you may often face situations when you need information about the ability of communication ports on a typical end-user system to handle large flows of data. If looking for a reliable COM port testing and analysis tool, look no further than COM Port Data Emulator! This compact tool was created for emulating a COM or Ethernet device, generating a stream of adjustable intensity, wrapping it into data packets (RS232, TCP/IP or UDP) and sending to a specific serial (COM) port. Test data can be randomly generated or read from binary or text files and sent to the port repeatedly or on the ad hoc basis. The software supports flow control for COM and RS232 ports, full duplex mode and is capable of operating both as a client and a server over TCP/IP. The built-in logging mechanism enables users to analyze the work of serial ports and their responses to the data stream being sent. You can also check the line status and trace communication errors
