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
