Does anyone know how to get a handle for a SerialPort.

I am trying to generate a IOCTL_SERIAL_GET_COMMSTATUS message.

I have seen that people say you can open(create new ?) the port as a file and so get a handle that way but I cannot see how to do this.

Maybe use: SerialPort port = new SerialPort("COM1");

If you need handle you must use CreateFile from kernel32.dll
[DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
private static extern Microsoft.Win32.SafeHandles.SafeFileHandle CreateFile(string lpFileName, System.UInt32 dwDesiredAccess, System.UInt32 dwShareMode, IntPtr pSecurityAttributes, System.UInt32 dwCreationDisposition, System.UInt32 dwFlagsAndAttributes, IntPtr hTemplateFile);

Open in new window
