The one on bbs.visualbasicforum talks about a direct IN & OUT
function in C(yuk). Is there anything like this in VBA? Memory
address accesses, aka Peek/Poke. I know how to do output in ASM to a
PC parallel port  - teach a class in basic  uP for Technicians and have
students do a "laser show"(simple image output) to one of my laser
projectors in class.
