This is the following Statement i get from Matlab after pressing "Verbinden"
>> versuchsstand
Serial Port Object : Serial-COM6
Communication Settings
Port: COM6
BaudRate: 57600
Terminator: 'LF'
Communication State
Status: closed
RecordStatus: off
Read/Write State
TransferStatus: idle
BytesAvailable: 0
ValuesReceived: 0
ValuesSent: 0
Serial Port Object : Serial-COM7
Communication Settings
Port: COM7
BaudRate: 115200
Terminator: 'LF'
Communication State
Status: closed
RecordStatus: off
Read/Write State
TransferStatus: idle

How can i Change the Status from Closed to Open, so that i can communicate with the connected devices.

You need to serial() to configure the settings for the com port, and then you need to fopen() the resulting object, after which you can do I/O with it.
