Product : C++Builder1.0 C++Builder3.x
Question:
How can I communicate to peripherals in Borland C++ Builder like using
"outportb",
"inportb" ."inp", "outp" in C.....?
Answer:
You can't use inport / outport any more. Win32 is more "protected"
than that, so it isn't allowed.
However, you do have a few different options.
Discussion of Port I/O under NT:
http://users.skynet.be/k-net/ParPort/index.html> Harold Howe has contributed something that you might be able to use> under win95 only:> http://www.bcbdev.com/components.htm
Also, if you are just doing work via the serial port, there are a couple
of other options:
1) Get a component to do the work. Check out commercial products listed
on the Borland web site:

2) Roll your own by using the Win32 CreateFile API. Check out the win32.hlp
file, as well as the following links:
