Toughie - Parallel Port

[josmond]

Does anybody know how to send signals to the parallel port .........i want to send a byte to the parallel port which has adddress 888 (binary)

i want to run a chaser unit which could be expandable to as many parallel ports is possible i think 3 X 8

3 X 8 = 24 channel chaser unit which can be customisable in any way you like!

any ideas???

There are great parallel port resources at www.lvr.com/parport.htm. One of the DLLs there (this one) is the same as Inp and Out in QB and will allow you to write directly to the parallel port, either the control register or the data register.

I have also written a small program to run with this DLL if you are interested, though there is a simple example included with the DLL.

In Visual Basic you'll need the file inpout32.dll and it's API calls to send and receive data through any port of your system.
I'll send you the file and declarations you need, if you are still interested.
I'll also let you know what pin at the Parallel Port what does.
