Knowledge Base FAQ Item #3100060
Q3100060: When I open a port, I get the following error: 30201 ("Cannot find specified devicename"). What does it mean?
This means that the Windows Telephony Device you are using, is NOT defined on the computer. You may have made a typing mistake. Error 30201 does NOT mean that the port is already in use (you would get error 30202).(viewed: 1333)
