This error has only been seen on the IBM Thinkpad T21 using an IBM 10/100 Ethernet Mini-PCI Adapter with 56k Modem (MiniPCI Combo), running on Windows 2000. Any attempt to use TAPI in TinyTERM gives, “Error (4555) Get property ‘IsConnected’ failed: Invalid object instance.”

No other TAPI-using application gives an error. Updating the modem drivers does not work. However, connecting directly to the COM port and dialing the modem manually works.
