Communication Functions and WIN32 SDK

Environment: VC++ 4.0 and Windows 95

How do you compile/link Communications Functions,
like SetCommState, in a 32-bit MFC application.

Here's what I've tried so far in an attempt to add
SetCommState() to my source file:

1. #include "winbase"   ---- this include file contains the prototype
2. Step 1 didn't work because the prototype is wrapped in #ifndef NOCOMM.

What is this all about? All I was able to discover is that NOCOMM is
defined when RC_INVOKED is true. I gleaned this from WINDOWS.H.

I searched MSDN to no avail, however all sample code was SDK
code, or .C files. Very curious.

I finally solved this by commenting out a line in my
STDAFX.H file.

//"#define VC_EXTRALEAN"

MFC adds this to remove rarely-used headers.
