I am trying to write a console application in MSVC++ 5.0, and am using some code I wrote in Borland a long time ago. Can I write an app that will run in DOS mode? the console apps I generate with the wizard are 32 bit?

I want to use some screen functions namely gotoxy, and cprintf and the like, how can I use these under MSVC++. I also want to do some comms with serial ports and the parallel port. I used to use outportb and inportb, what are the MS versions of these functions?

Thanks.

With VC5 you can write console Win32 programs using the Win32 API and runtime library.  The plus is that you get lots more memory and access to all the Win API, the minus is that nearly all the naughty (but fun) DOS stuff isn't allowed.

If you need to write true DOS apps, you need to use VC1.51.  This comes on (some only) copies of VC5 and VC4 CD-ROMs

A win 32 console app can move the cursor around on the screen (and do a lot of similar stuff that would be hard to do under DOS.)  Look at SetConsoleCursorPos()

For the serial communications you can use

#include <conio.h>
_inp and _outp

just keep in mind that windows may cause conflicts on some devices.

_inp and _outp are unavailable in Win32.

I am currently using _inp and _outp in my Win32 applications.  I am writing to both COM and LPT ports.  I haven't had any problems.

If you think my answer helped you the most then I will gladly accept the points.  Your question actually had a couple parts, I only answered one.  If you feel that someone else helped equally or more, you can reject my answer and we can split the points or something.

I'm glad I could help..

Its fine, I didn't really need the gotoxy stuff as I rewrote a windows app to handle it, and just supplied an interface.

Thanks.
