If you have a simple single-threaded and single-connection application
without GUI: Yes.
The problem with the Sleep API is that it totally stops Windows
message loop processing and it completetly blocks the application.
There is not problem with that as long as you are sure that there
are no side-effects arising from this.

If you are accessing the COM port directly, don't you need overlapped
I/O as well?

No, the sample was taken from our SMS sending component, which is a bit
more complex, but the connection method is 70% of what I posted. (I stripped
out some additional checks, methods for cancelling, address selection, debug
outputs, etc..) But basically that's it.

Why? Probably because you don't know it? Using a COM based API in a
COM oriented development environment is the most natural and easiest
thing you could do. TAPI has a lot of complications, but just making a
simple data connection is really easy, even for a beginner.

OK, if you were talking about TAPI2 and VB I understand your concerns
and I must agree.
