Porting from DOS to W32 - COM port

[Martins]

I need to port an application from DOS to W32.

The application wrote and read the hardware directly.

I know I need to use W32 SDK to access COM ports (USB Devices),
obviously the Windows way.

Several questions:

What should I download (of course I have the compiler - C++ Builder 6)?
I suppose I don't have to download the comllete SDK.

What is the relation of these matters with Net Framework?

Thanks
H. Martins

Definately a windows question. Try in one of the microsoft groups. I
normally suggest microsoft.public.vc.language

Then ask on a windows group, this is OT here

If you have Borland C++ Builder 6, you do also have the platform SDK.
Of course not a updated SDK but it dont matter when its only COM port
communications.

HANDLE ComPort = CreateFile("COM4", GENERIC_READ | GENERIC_WRITE, 0, 0,
OPEN_EXISTING, 0, 0); // Open COM port 4

You can then use ReadFile() and WriteFile() to send data on the port.
There are also GetCommState(), SetCommState(), GetCommTimeouts(),
SetCommTimeouts(), possible more cant remember them all. You can look them
up at msdn, and msdn has sample code as well.

Borland C++ Builder has absolutely nothing to do with .NET framework.
However, you can use .NET from unmanaged C++, or from VB6 for that matter.
If you're working in .NET im sure there is a wrapper/class that makes it
very easy to use a serial port/usb/whatever.

You can get more help in comp.os.ms-windows.programmer.win32 and i guess you
can finde some groups that are more related to .NET programming as well.
