TAPI - How does it connect?
How does TAPI connect to my telephone line?
Years ago I wrote a visual basic phone dialer which has worked fine for years using Com 3. Historically I have also used software called PhoneTrayFree that provided Caller ID and provided selective call blocking. I would simply, in code, “kill” that process when I ran my dialer and then reinstate when the later closed. With a new USB modem and Windows 10 my dialer will not connect showing another program using the COM port. It is not PhoneTrayFree and I cannot identify, but found a workaround using TAPI in my Visual Basic dialer code - no more Com number.
I am 88, my fundamentals are weak, fear they never will be strong but hopefully can understand how TAPI avoids the COM ports, the old 9 pin serial connections.
