I know that VC has the MsComm control which I have used in VB, however I
would rather stay with a class or API calls.

I am primarily interested in a method whereby the reception of serial data
would cause an event to be fired that I could then use to call a receive
routine.  Instead of me polling the com port I would like the com port to
call me (like an Interrupt would).

I also know that I could create a thread to poll/read the com port and have
it call me back when data was received, however I was interested in a
built-in method if available.

Thanks in advamce for any help or suggestions.

Have a look at the MTTTY sample on MSDN. That's a fairly comprehensive
example of serial comms under Win32. There are no class wrappers in
VC++, but there are several available online - try the codeguru or
codeproject web sites.

Look in C++ developer's Journal's archives, in '97, I think. Look for
"woodruff". The site is probably http://www.wdj.com, but I'm not sure.
