Move from MC55i to PLS62T-W USB via RS232. What is the difference? | Telit Cinterion IoT Developer Community

I used the Cinterion MC55i terminal via RS232 for years to send and receive SMS messages. After opening the COM-port I started with AT+CFUN=1 and went on from there.
Now I replaced the MC55i with a Cinterion PLS62T-W USB terminal, also connected via the RS232-port to the RS232-port of the Windows-PC as before.
After opening COM1 I sent AT+CFUN=1 and was hoping it would work.....
But no, no response. Nothing at all. Also not an error. Just nothing.
So obviously something is different between the 2 terminals.
I have to start different or have to configure something first.
Can somebody give me a push in the right direction?
With kind regards,
