New to TAPI, old to forgotten Com ports and use of SerialPort control. I have used the TAPI function tapirequestMakeCall in Library “TAPI32.dll to dial a selected phone number. Works fine but starts and minimizes Dialer.exe which is not needed or wanted. Am I using the wrong function? There are others such as MakeCall and lineMakeCall but I have found little to help me understand. Mind you I am an old retired guy and hope you can teach an old dog a new trick.
