How can data be read from a device connected to a computer via a COM port using a .NET console application? The device measures the weight of heavy vehicles and is connected to a weigher that displays the results. The existing application on the computer is outdated, and support is unavailable. Any guidance would be appreciated.
I appreciate any help you can provide.

There is the SerialPort class. However, bear in mind that it's not held in high regard!

Use System.IO.Ports.SerialPort.

Hi,
In my console application I am setting connection parameters as follows;
public async Task StartMeasuringAsync(CancellationToken cancellationToken)
{
const int baudRate = 1200;
var availablePorts = SerialPort.GetPortNames();
if (availablePorts.Length == 0)
{
LogWithColor("No COM ports are available.\n", ConsoleColor.Red);
return;
}
LogWithColor($"Available COM ports: {string.Join(", ", availablePorts)}\n", ConsoleColor.Green);
foreach (var portName in availablePorts)
{
LogWithColor($"Attempting to connect to {portName} at {baudRate} baud\n", ConsoleColor.Yellow);
try
{
_serialPort = new SerialPort(portName, baudRate)
{
DataBits = 8,
Parity = Parity.None,
StopBits = StopBits.One,
Handshake = Handshake.None,
};
_serialPort.Open();
...
Should I also need to change the connection parameters on the device manager?

It is not necessary to match them, but if any problems arise, matching the properties may resolve them.
The weird thing is I can't read the raw data from the PWI-T device. Is there a tool that I can install to my Windows machine in order to monitor serial port data?

I downloaded Realterm, hope I can monitor device data with it :)
