Comport callbacks or objects

Comport callbacks or objects

(OP)
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.

RE: Comport callbacks or objects

You might want to look at the following web sites for some "simple" components. On 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 www.vclcomponents.com go to their I/O Communications page. They have some freeware components that should work; see: Asyncfree and cport260 for starters.
