At first I thought it was me, that I forgot something.
So I downloaded SerialPortLearn.zip, from Hari Wiguna found here: http://forums.netdui...rt-code-review/
and I get "serialPort.Position' threw an exception of type 'System.NotSupportedException' long {System.NotSupportedException}" for Both position and length property.
BTW, this is thrown directly in the constructor for SerialPort.
Is there another assembly than System.IO.Ports that I should reference for SerialPort ?
Thanks for your help, guys, this is really blocking a project on which I need to move on.
