I have a Creative Labs 56K external modem. Device manager shows the driver for it as being installed and working properly. The COM port is also installed and workng properly. The modem is recognized by Winfax Pro, which installs it and shows that it is responding. But when trying to use hyperterminal or Winfax the system reports that the TAPI modem is unavailable - in use. I have rebooted several times in an attempt to remove the problem - no luck.
