And why do you think anyone here will know? We have no idea what the contents of that file are, or what you expect when you send it out through the serial port.

Please edit your question and really show what you have tried, and explain any problem(s) you encountered.

Solution 1

Create a SerialPort instance: SerialPort Class (System.IO.Ports)[^], set the interface parameters correctly so they match the equipment at the otehr end (the link includes an example) and open it.
Then read the file and send it:

C#

byte[] data = File.ReadAllBytes(pathToDATFile);
mySerialPort.Write(data, 0, data.Length);

Then use a StreamReader and the Read method.
