outportb() / inportb() and Win32

[Pegboy]

I am updating a utility to capture serial port data that was originally
developed as a DOS app using the outportb() and inportb() routines. I am
trying to re-work it as a Win32 app using Borland C++ 5.02, but am finding
that outportb() and inportb() are not available for a Win32 target. There
is no fancy flowcontrol or packet protocols being used, just simply
capturing incoming serial data.

What is available to me for such simple serial port development in a C
application for Win32?

Thank you for your help.

Windows does not allow direct hardware access. You need to
use the API.

You should know by now that your query is completely
off topic for comp.lang.c.

Visit newsgroup comp.os.ms-windows.programmer.win32
for Win32 issues.

inportb() etc are not C functions, they're DOS specific stuff. As such
they're offtopic here.

Because they're DOS functions...

A windows programming group could probably tell you, eg in the
microsoft.win32.programmer.... heirarchy.

Be prepared for it to be somewhat harder tho, as user-mode apps do not
have hardware access under windows.

I was having similar problems, but they got solved when i used the old version of Turbo C Borland version 3
