I am getting the following error when attempting to use MSCOMM for the first time:

OLE Error Ox8000ffff: Catstrophic failure

The error occurs in the following code when setting the com port:

***

oComm = CREATEOBJ('MSCOMMLib.MSComm')
oComm.CommPort = 1
oComm.Settings = "9600,N,8,1"
oComm.InputLen = 0
oComm.PortOpen = .T.

***

Am I missing anything?
Note: I am using WinNt(sp3) and MSCOMM32.ocx is in c:\WINNT\system32
