☞ If no device is connected or still switched off when starting the program, no
measured values will be indicated, i. e. these fields will remain empty.
In case of an existing connection, the messages COM and the nos. of the enabled
interfaces will be indicated in a message. If there is no connection, the message
No COM will be displayed.
