Direct I/O output

[GDGarth]

I'm trying to control a relay output card. The programming instructions are not clear.

To turn on a relay, you need to write a byte to the base address (992 or 3E0 Hex). How do I do this?

Their example is this:
Base = &h3E0 'Base I/O Address
Out Base,2 'Turn on Ch 1

I can't find an "out" function. Output, write, and Put seem to want to put the data into a file.

Print needs an object.

I'm using VB Version 4.0

I found the solution in my old Dos version of Quickbasic. They have a function called "Out", that writes directly to the address. I can't find the equivalent in VB.

You must use API like inpout.dll or portio.dll for do that in VB
