com 1 port usable?

Hi, i want to use COM1.
so i dissabled debug info on com1

and used this code:

SerialPort _serialPort = new SerialPort("COM3", 9600, Parity.None, 8, StopBits.One);
_serialPort.Handshake = Handshake.None;
_serialPort.WriteTimeout = 500;
_serialPort.Open();
_serialPort.Write("Helo World!\r\n");
_serialPort.Close();

i see in the registry that UART1 = com3 right?
that's why i'm using COM3 here.... (i tried them all...)

nothing is recieved on the oter end (pc)
Is UART1 freely usable?

kind regards

ok, i found it...
i MUST use COM1 for uart1
but i have to kill netdcu process....

i will look if i can see to not start the process anyway....
We need also that com port...

i think the labels on the starterkit print are wrong than...

what is the function of the ndcucfg process?

yes of course i used this tool...

but why is the process running? and why does it needs to start automatic?

i always make telnet connection....
first time use: i use discover tool to get the ip-nr of the dhcp ethernet port.
and than i can use telnet to connect to the device.
