How to generate a EV_RING event in rs232 serial COM port? visual c++ 6.0

[Laura Lucas]

Hi
I'm working with visual C++ 6.0

I can detect when an EV_RING event is generated with:

BOOL WaitCommEvent(
HANDLE hFile, // handle to communications device
LPDWORD lpEvtMask, // pointer to variable to receive event
LPOVERLAPPED lpOverlapped, // pointer to overlapped structure
);

I want to SEND an EV_RING event, generate it.
Any idea as to how to do it?
I can send characters, but not this particular RING event.

Thank you!

Please post MS Windows programming questions to the newsgroup where
they are on topic: comp.os.ms-windows.programmer. Another choice is
the VC++ newsgroup: microsoft.public.vc.language (although yours is
not really a _language_ problem, is it?)

Ok sorry, I will post my message to that groups too. So, in c++, any
function or method or anything to send something to a serial rs232 COM
port is inexistent? There isn't anything multiplatform? :S

thanks!

Of course there isn't. Hardware is _always_ OS-specific.

The language (discussed here) and what you can use it for (discussed
in other groups) are different things. C++ is a general purpose
programming language and can be used for just about anything. We need
to limit the scope of discussion to avoid the "just about anything".

Your question is off-topic here.
