Comport callbacks or objects

[tcollins]

I need to know how to do Com/SerialPorts in Borland C++ 5. From what I see, its pretty easy to set one up and write to it using the Win32SDK (CreateFile(), ReadFile(), WriteFile()), however, a callback function for incoming data would be welcome...byte per byte would be better. Or if I could find a Serial Port object/control in Borland that I could just drop onto the form, that would be welcome as well. Then it would know the method to call to give me my data. I really don't want to have to hand code a messaging loop doing the PeekMessage() GetMessage() thing myself.

Any help? Thanks.

You might want to look at the following web sites for some "simple" components. On

http://www.bcbdev.com

go to their FAQ page, then to the Window Systems section. There are a couple of questions there about IO ports. They have examples of code and some downloadable files to look at. On

http://www.vclcomponents.com

go to their I/O Communications page. They have some freeware components that should work; see: Asyncfree and cport260 for starters.
