It's not really anything to do with Vista. There are simply some problems
using MSComm32 with some virtual com ports. This generally happens when using
virtual com port drivers with usb-to-bluetooth or IR etc.

You'll know when you have this problem because you'll be able to send data
but when you call Input you'll trigger a runtime 8020 error.

Using a control such as comm32.ocx there is a property you can use to avoid
the problem.

Sorry, in my previous post I gave the wrong link - it should be:-
