I am using Microsoft website code, this machine is a notebook:
Using System. IO. Ports;
String [] ports=SerialPort. GetPortNames ();
Console. WriteLine (" the following serial ports have been found: ");
//show all serial
The foreach (string port in ports)
{
Console. WriteLine (port);
}
Console.ReadLine();
