I'm trying to install modem drivers on your virtual COM ports and Windows XP/2003/Vista is saying that these drivers are not signed. Is this a problem?

No, the modem drivers should work fine.

In many cases the modem drivers can not be signed as the XP/2003/Vista certification process involves testing the drivers with dial-in to the modem, which some modem servers do not support.

In other cases, the modem drivers were written before Windows XP was released and the drivers are no longer being updated. We have not seen a case were this causes problems with using them on Windows XP/2003/Vista PCs.
