MSCOMM32.OCX and ComOutput function

Hello,
VC++ 4.0 under Windows 95
Does anyone know how to send binary data with the MSComm control?
In the OLE Control help file, it mentions 2 functions, ComOutput & ComInput.
But when I insert the OLE control into my application, and it (Class Wizard)
creates a control class, it does not create wrappers for these two functions.
I've tried using SetOutput(), but I'm not quite sure what Variant type to use.
BSTR have a trailling NULL which I do not need, and I'm not sure if
COleVariant is what I'm looking for.
Any insight or examples are very much appreciated.

Refer KB article Q147740 "How to Handle Events for OLE
Controls in a CWnd" in Microsofts's Knowledge Base. I ran into the same
problem sometime back.
