Gee, Bernie!
That looks great. I've just downloaded and we'll see what we can do with
it...
Thanks!

3. RE: Driving COM ports
OK, let's cut the laughs. I program in Euphoria because it's easy and I
can forget all the nausea of Windows C++ coding. This lot you recommend
does show how to make a simple teletype to demonstrate driving COM
ports. But the basic program is 2000 lines long, and you have the .rc
and .h and so on too. It would take me ages to convert that to Euphoria,
and I would hardly be Euphoric doing it. No, what I need is a EU
package to do it, nice and easy. Give it a port, baud, etc, and a
callback id for handlers to TXBE and RBF interrupts, is all I need. When
I want to get back into C++ Windows coding I'll shoot myself first.
Thanks anyway.
Anybody else out there listening?

I don't think anyone's done a lot of work on wrapping this for windows. The
first thing I'd try (and I'm real shaky here) is simply using Eu's open() to
do stuff on the ports. There was a discussion a bit ago about that (maybe
you were part of it).
Failing that, I'd recommend downloading the win32.hlp file off the archives,
and check out the Communications section in the contents. You should be
able to do everything there. It won't be as messy as the VC++ sample Bernie
directed you to, but you will have to do some interfacing with C (namely,
kernel32.dll).

That was not meant as a joke, I only meant it as a example that
you could get some ideas from. You said that you want to use
interrupts which means that you want to be sure that you don't
miss any data that you receive ( no easy task ). Windows does not
want you messing with the ports directly ( another problem )
because of security, etc. In other words, port I/O in Euphoria
may be difficult to do. Thats why I think that nobody has tackled
the task in euphoria windows.
