I need to know how to write data to(and read data from) the usb and serial com ports.

I am using Microsoft visual studio.net (2003).

I believe you can use C's standard fwrite and fread statements to do this. But you have to be able to open up a stream to these ports in order to make it happen.

Can you help me with this question?

Don't post questions as topics in the Tutorials forum; that's for submitting tutorials.

You could start by looking at these links:

Serial Port Central

Windows Serial ports

Reading a Serial Port using Windows


If you need more information then I Would suggest: Google. Once you have a program and need specific help then post the complete code in question and any error/warning messages, and the specific questions.
