Serial Port Programming with C/C++

[deanlwvu]

I am wondering how to get I/O with a serial port in C or C++. All I need is to read incoming data, which is already working. I am currently using the BIOSCOM functions, but that does not work because I am using RS485 instead of RS232. The program works with RS232. What's the easiest/simplest way to do this?

Thanks,

hi,
i guess that the header file is called dos.h
and you can use inportb and outportb.
i did that as a student and it works fine but you got to use interrupt functions.
hope it ll help you

I am yet to program a windows terminal program for the serial interface. Currently learning Visual Studio.NET and teaching myself what to do with the serial interfaces.

I will post my future findings in this forum.

In which case, you can forget about all this inport() stuff and use the proper win32 API functions which begin with

dos.h, bios.h are but a distant memory...

Yeah, I'm aware of all of that. I have a lot to learn before I ever implement serial interfacing with .NET. I appreciate the input though.
