Serial Class

[analizer1]

Hello
I am working with Serialclass and this is working just fine...i have a 3rd
party dll for zmodem, xmodem , etc
which uses the port handle to gain reference to open port..how to get the
port handle from serialclass
so the file transfers can use the port

thanks

You don't. AFAIK, if you need a file handle for use in unmanaged
libraries, you have to use CreateFile() via p/invoke to open the COM port.

Right. That's why I wrote "you don't". AFAIK, you can't use SerialPort
at all if you want access to the underlying file handle.

See MSDN and http://www.pinvoke.net/
