low level input from address 0x31d

[bigmonkey70]

I am on a automatic conveyor belt project and need to read an input from interrupt address 0x31d.

Is there any function in VB that can read data from a low level input?

Thanks

forgot to mention, to stress my question a little further, is there any function in VB6 that are similar to inp/outp in C++

Thanks

Declare Sub vbOut Lib "WIN95IO.DLL" (ByVal nPort As Integer, ByVal nData As Integer)
Declare Sub vbOutw Lib "WIN95IO.DLL" (ByVal nPort As Integer, ByVal nData As Integer)
Declare Function vbInp Lib "WIN95IO.DLL" (ByVal nPort As Integer) As Integer
Declare Function vbInpw Lib "WIN95IO.DLL" (ByVal nPort As Integer) As Integer

Note that WIN95IO.DLL won't work under NT, 2k or XP. You would probably need to do a C++ DLL and use that - dunno about timing implications though!

Thanks everyone. I found the library I needed. It's the inpout32.dll and it does work under nt/2k/xp
