My conclusion so far: TCP/IP is ok, Serial i can't say anything about yet. Need more testing.
First i tried connecting with Bert's RFXCOM receiver without using the ComPort Redirector (CPR):
As you can see, i had no problems at all.
Next i downloaded & installed the CPR. Tests with the CPR gave me the results you can see below, so this looked ok too:
The "closed" is because i closed the connection myself before screendump. But it received things...

Next thing was trying to connect with RFReceiver the COM way. But RFReceiver had problems finding COM3:
Where the Device Manager shows this:
However, no worry yet, i remember seeing that behavior before on my own HA PC a couple of weeks ago, when using the CPR for talking to the serial module built into my Ethernet Interface.
Don't know anymore how i solved that, but eventually i got it working. So it's not over yet...well, tomorrow there's another day...
