Mscomm PortOpen error – does anybody REALLY understand this error?

Hi Everybody:
I’ve run across this error on several computers and much has been written
about it on the web but no one seems to understand what causes it or how to
fix it.

The problem became evident when I was trying to use the “Dialer†sample code
in Visual Basic. ALL the ports came back with a “Run-time error 8012 device
not open†even when the statement before it is: “MSComm1.PortOpen=True†and
of course the state before it is “MScomm1.ComPort = 3†the port number to my
modem. Similar problems exist on the HyperTerminal. The HyperTerminal won’t
work on COM 3 my modem port number, it will work on GTW V.92 Voicemodem the
name associated with the modem, and of course non of the other port numbers
won’t work either. I’ve tried changing the port number of my modem and in
the Visual Basic sample program, but the problems remained the same. Does
anyone really know how to fix this problem?

Thanks
Kurt
